How to flush the engine after the emulsion. How to properly flush the engine with diesel fuel before changing the oil. The need to remove water-based paint

Good afternoon. Today we will talk about how to flush the engine cooling system from oil? This is especially true for cars equipped with automatic transmissions and oil-to-salt heat exchangers, since the risk of oil getting into them is much higher. The article discusses working flushing methods, and popular misconceptions.

This article is based on my own experience! All tips in the article are tested in practice!

The main problem when oil enters the coolant is the formation of an emulsion.

It looks like this:

The main difficulty with the emulsion is that it clogs all the hoses, pipes, and the engine starts to overheat. Those. it flows very slowly and does not remove heat, and it is quite difficult to wash it.

Non-working ways to flush the cooling system from oil (popular misconceptions).

Flushing the cooling system with plenty of running water.

We brought the radiator to the garden and flushed it with reverse flow, water from the well. It did nothing, it drives out large drops of oil with water, but the emulsion on the walls is not washed off (cold water cannot soften it). It takes more than one ton of very hot water to completely flush the cooling system from the emulsion.

Hot water is EXPENSIVE, not everyone has access to unlimited freebies hot water, respectively, we write to non-working methods.

Flushing the cooling system with whey.

I read this method on the Internet and decided to check it out.

The washing procedure is as follows - we drain all the liquid from the cooling system and replace it with milk whey, in the warm season we ride for 2-3 days, drain the inversion, rinse 2-3 times cold water and top up with antifreeze.

Whey is freely sold in dairy departments.

We tested this method after flushing the cooling system with water more than 10 times, and flushing the radiator with reverse flow.

We also write the method as non-working! No, the serum merged black and it washed out some dirt, but it washes the emulsion no better than water!

Partially working methods for flushing the cooling system.

Flushing the cooling system with FAIRY dishwasher.

The flushing procedure is as follows - fill in the detergent (about a glass of 10 liters), warm up the engine to operating temperature and drain all the liquid from the system.

Repeat if necessary.

At the end of flushing, we flush the cooling system 2-3 times with water, drain everything and fill in antifreeze.

Partially working method The detergent does partially remove the oil emulsion, but it falls off in rather large pieces that do not pass through the radiator cells, thermostat and thin cooling system hoses.

I summarize - you can rinse, but the product is not effective enough, it breaks down the emulsion, but it does it in large pieces that do not pass through the radiators.

Flushing the cooling system with automatic powder.

The method is somewhat better than washing the dishes detergent(less foam), but fundamentally no different.

The only method of flushing the cooling system that worked was flushing the cooling system with SOIL FUEL (DT).

Desperate to wash the engine of the emulsion, I ventured to flush the cooling system with diesel fuel.

The methodology is as follows:

Drain all fluid from the bleed system
We remove the thermostat (otherwise there is a possibility that the large circle will not open and the radiator will remain clogged)
Fill the entire cooling system with diesel fuel (at a minimum).
We warm up the car to operating temperature (we stand still, do not drive, warming up without a thermostat will take about 20 minutes)
We merge everything from the cooling system (I merged black diesel fuel)
Flush the system with water 2 times
Pour antifreeze

Many are afraid to do this, fearing the ignition of diesel fuel - nothing will happen to it, do not forget to remove the thermostat, otherwise it will not work to flush the radiator.

Some are afraid for the safety of the nozzles, the nozzles can swell and deteriorate from fatty diesel fuel - this is also nonsense! From an oil emulsion, they will swell much faster.

Methods that have not been tested.

Acid wash.

Here I include washing with carbonic acid (carbonated water), acetic acid, citric acid, it is obvious that these acids will not take an oil emulsion. But it is quite possible to flush the cooling system from scale and dirt.

Washing with soda.

Soda will also not remove the oil emulsion, but aluminum will thank you for it! When flushing the cooling system with soda, it is diluted in a proportion of 100 g / liter.

Painting is the most used method for finishing walls and ceilings. And this is understandable, because this material is easy to use, even for the owner of an apartment or house without experience in conducting repair work, it keeps on surfaces for a long time, and its decorative possibilities are endless.

Important! Please note that a solvent will not work in this case, as it can contribute to even deeper penetration.paintsinto the thickness of the materialsemi.

Method 5 - cleaning water-based paint with solvents

For efficient removal there are many such solutions. chemicals.

For stubborn stains and thick layers of dried paint, use products with a high content of solvents. It could be:

isopropyl alcohol;
formic acid;
dimethyl chloride.

All of them are safe for the surrounding area, and quickly decompose. The consumption of the substance is on average 1 liter per 5 square meters.

But there are other solvents containing toxic agents in their composition that cause side effects for human health. Therefore, when buying such a wash, carefully read the composition, especially if there are animals or children in the house.

Method 7 - for professional builders

This option provides for the presence of special tools: a building hair dryer and a drill with a grinding nozzle.

Cleaning the coating from paint with a building dryer using high temperature happens like this:

Take a hair dryer, turn it on.
Visually divide the treated area into small zones.
Direct hot air to the painted area.
If the tool has a built-in paint stripper, scrape in a linear motion in one direction. As the substance sticks, remove it with a separate spatula.
Remove the swollen warm paint with a spatula.
Remove the remaining traces of paint with a wire brush or sandpaper.
Vacuum, do wet cleaning.

Method 8 - using a grinder

An effective method for removing thick, hardened layers of paint is to use a sander. You can take a drill with a special nozzle for removing paint in the form of a round brush with iron bristles, or a metal nozzle-crown. Nozzles are sold at any hardware store.

Water-based paints are one of the most common, they are used both in repair and finishing work and for artistic creativity, because in order to wash water-based paint from clothes, you need to know in advance and have the right tools on hand.

Water-based paint is loved by both professional builders and home craftsmen for its excellent specifications, this material:

easy to apply;
dries quickly;
practically odorless;
looks great after drying.

And most importantly - if the paint gets in the wrong place, it is easy to clean it with improvised means. It is also liked by parents whose children are fond of artistic creativity - watercolor and gouache are easily washed off with ordinary water and soap from any surface.

Traces of paint do not want to be washed off only if they are immediately forgotten and they have had time to dry. How to remove water-based paint from clothes in this case is described in this article.

The better way to wash water-based paint from clothes depends on what basis it is made of.

Dyes based on polyvinyl acetate - that is, the most common PVA glue - are effortlessly removed from the fabric during normal washing with soap or powder. you don’t even need a long soak, you just need to wipe the stain under a stream of warm water, and then send the thing to the washing machine.
Acrylic paint is resistant to water of any temperature, if such a stain is simply soaked in a basin of soapy water, it will soften, but will not go away. Therefore, you will need a spatula or brush to scrape it off. the remaining trace is removed during the standard wash.
Watercolors and gouache paints are water soluble. To remove a stain from such a dye, it is enough to turn the fabric inside out and substitute it under a stream of water. A fresh stain will be removed even without soap or powder.

A fresh stain from any water-based paint is easily removed with medical alcohol or ordinary vodka. It is necessary to stretch the fabric and moisten it with alcohol, then rub it a little and wash it under running water.

When choosing a means for removing traces of paint from textiles, one should take into account not only the type of water-based paint. Equally important is the type of fabric, especially when dealing with old stains.

How to remove water emulsion from different types of fabric

If a working robe is dirty in water-based paint, then you don’t have to worry too much. Firstly, overalls are then put on so as not to spoil beautiful everyday clothes during repair work, and secondly, robes are sewn from dense fabrics that easily endure both intense mechanical stress and caustic chemicals.

Such textiles, as well as denim products, can be safely treated with acetone or white spirit, after which the cleaned textiles are placed in the machine and washed in the usual way. What about more delicate fabrics?

When fine natural fabrics, such as chintz or silk, are contaminated, it is better to use refined gasoline. Blotting paper is placed under the stain, after which it is gently wiped with a cotton sponge dipped in solvent. You need to move from the edge of the spot to the center. If required, the blotting paper and cotton swab can be changed in the process. After this treatment, the thing must be washed and dried in the open air.
Synthetic fabrics cannot be cleaned with gasoline. This substance and other aggressive solvents disrupt the structure of fabric fibers and can even completely destroy them. Therefore, vegetable oil is used to remove water-based paint. A piece of cotton wool or a clean cloth is moistened in oil, a sheet of clean paper is placed under the stain and treated with oil. the stain will not go away immediately, you will have to be patient and do not forget to change the cotton pad and blotting paper from time to time. Remove traces of grease with dishwashing detergent. and then the product is washed in the usual way.

If the pollution is very strong and old, and the listed means did not help to cope with them, you should use a knife, razor or scraper, acting carefully and slowly.

In kindergartens and schools, drawing lessons mainly use watercolors or gouache paints. And even if the child puts on an apron, sleeves or even a dressing gown, stains on clothes still cannot be avoided. If glue-based paint stains remain on a blouse or panties, or on a school uniform made of thin wool, this recipe will help:

mix a tablespoon of ammonia alcohol and oxalic essence;
dissolve the resulting mixture in a glass of water;
gently treat the stains, then immediately wash things with washing powder.

If the fabric is dense, you can add a mixture of ammonia and oxalic acid to a basin of water and soak the soiled items in it until the morning.

If stains from acrylic paint remain on the textiles, then you will have to use a more caustic composition. To prepare it, you need to combine ammonia, table white vinegar and table salt in equal parts.

Spots are rubbed with this paste and left for a quarter of an hour. Then the stains should be rubbed with a brush and rinsed in cool water. If they do not move away, the procedure is repeated. But you should not abuse such a tool, as it can change the color and structure of the fabric.

In the most extreme case, if none of the listed methods succeeded in removing the stain, and the thing is expensive, you can contact the dry cleaner.

beautiful ceiling not only decorates the room, but also visually enlarges it. It is not necessary to completely change the entire design, you can simply update old design paints and varnishes. Today, such tools can be easily purchased at almost every hardware store. Before painting the ceiling, it is necessary to remove the old layer to the plaster in order to ensure better adhesion of the material to the surface.

Peculiarities

Emulsion paint removal work always entails the formation of a large amount of dust and dirt. Often, the removal of its layers takes a long time and is quite laborious, since the characteristics of a particular composition are not taken into account in advance. That is why you must first evaluate the features of the product applied to the ceiling.

Water-based paint is of two types:

Waterproof. This group includes most of the materials that, after complete drying, become resistant to moisture. The use of such funds is appropriate in rooms with increased level humidity and on the outer walls of various buildings.
Not waterproof. These products are not resistant to moisture, so they are used for dry interior parts of the premises.

If you consider the type of paint before removing it, you will greatly facilitate your task and do the job better and faster.

What to wash off?

Moisture-resistant is water-based paint based on PVA. To remove its layer, you only need a sponge with soapy water.

To clean acrylic paint that is resistant to water and soap, it is necessary to use mechanical means - a spatula or an angle grinder. Another great way to remove paint is to pre-pasting the surface with newspapers. To prepare the glue, boil starch with sour cream, you can also purchase ordinary wallpaper glue. After the glue dries, it will be much easier to remove newspapers with paint.

Often the tool is removed with a chisel. This process will take you a lot of effort, but the result will please you, the paint layer is removed efficiently and silently.

A construction dryer for removing varnishes is also often used. This tool heats up the area with the old coating as quickly as possible. Additionally, you can use a spatula. This method is used to remove acrylic water-based paint. And chemical-based products applied to the surface with a roller are absorbed into the substance and destroy it, being another effective method removal of the old coating.

Preparatory work

Before removing the old coating from the surface, you must carefully prepare for this work. Absolutely all things that can be damaged or heavily soiled during repairs must be taken out of the room. If something is left in the room, cover the item with plastic wrap. If you do not plan to change the floor, also cover it with a film.

Depending on the water-based paint removal method, prepare in advance necessary tools. To maintain personal safety, be sure to use:

respirator;
building glasses;
cap or panama;
gloves.

To clean the ceiling, install a ladder, the condition of which also check in advance. Think about where to put the tools so that you can easily access them.

How to wipe quickly?

There are a few good methods with which you can remove water-based paint:

Mechanical cleaning - the roller must be moistened with water and walked over the surface. After 15 minutes, remove the old coating with a spatula. In areas where it does not wash off, use a brush with metal bristles.
You can remove the varnish with a soapy solution, which must be applied to the surface with a brush and left for a few minutes. Then carefully wipe off the solution, making sure there are no streaks. If there are stains, then wash them off with warm running water.
Wiping off old dried stains on your own is easy. Soften the paint with warm water. If the stain is large, then put a wet rag on it. After half an hour, wash the stain with a brush.

Emulsion paint can be cleaned using special tools. Modern market offers a wide range of substances that allow you to remove more than one layer of paint in a few minutes.
You can clean the surface of old water-based paint with a grinder. Take a drill with a round brush head with iron bristles. This cleaning method is used for wooden floors and walls. But with a grinder you can wash the paint from concrete.
It is also possible to wash clothes from contamination with paints and varnishes. To do this, soak things in warm water with washing powder. For more greater efficiency Pour dishwashing detergent onto stains and leave for an hour. Then rub your clothes well.

Surface

Water-based paint can remain absolutely on any surface. But it is quite possible to wash it off both from clothes and from the ceiling, floor and walls:

To wash the floor covered with parquet from dirt, it is necessary to use special tools. Works well for this task methyl alcohol You can also use acetone or vinegar. Apply the product to a damp cloth, wipe the area of contamination with it. Then wipe with warm water and let the parquet dry.
Linoleum - flooring, which is often found in modern houses and apartments. Wash such a floor with warm water and neutral cleaners. If traces of paint, felt-tip pen or iodine were found on the floor, then kerosene, gasoline or turpentine will come to the rescue. All these tools negatively affect linoleum, so they should be used in minimal quantities and only when absolutely necessary.
It is easiest to remove water-based paint from tiles. A sponge and chemicals will be enough for you, since the tile is resistant to chemicals, and thanks to its glossy surface, the paint does not penetrate inside. It is not difficult to wash off the paint and varnish material from the tile.
Emulsion paint can be removed from the door with a spatula. Wet the surface with warm water and let it soak. Remove the old paint with a spatula.

Material

Removal paintwork materials from surfaces from various raw materials is performed different ways. So, for example, when working with plastic, you need to be as careful as possible, because mechanical way may damage the surface. It is effective to use liquid glass or silicone sealant, which, when dried, destroy the paint, and it simply comes off the surface. Silicone hardens throughout the day.

After drying, a deep incision is made with a sharp knife, but be careful not to damage the surface of the plastic.

Often during coloring window frame, the paint falls on the glass. It's good if you notice the stain right away, because fresh dirt is much easier to remove.. If you do not notice the contamination immediately, you will have to use a sharp knife. wet the glass hot water and gently wipe off any dried paint.

You can also resort to the thermal method using a building hair dryer. Direct a warm stream at an angle at the glass and hold it until bubbles form. Then the paint can be removed from the glass with a metal spatula.

It is also possible to remove emulsion paint from wallpaper. If the paint is still fresh, then you can wipe it off with a cotton pad and makeup remover. If the substance has already dried, then you can tap on it and gently scrape it off with an iron tool. Wipe remaining paint with acrylic nail polish remover.

To make the removal of paint and varnish materials even faster and better, the following recommendations must be followed:

Varnishes from some surfaces are washed off with soapy water. In such situations, water must be applied to small areas, otherwise the surface will dry out quickly and the procedure will have to be repeated again.
If paint gets on the surface, wash it off immediately before it dries. Dry traces of paint are more difficult to deal with.
If the product gets on clothes, it should be washed with water or blotted with a napkin as soon as possible.

Interior decoration is not simple building process. It involves a lot of effort in its implementation. Today, people want to carry out repairs on their own to save money, and sometimes to show their talent. This fact is especially important for owners who are engaged in painting their house or apartment.

Stains of water-based paint - a common problem after repair

One of the favorite means of repair is water-based paint - this is a sought-after, high-quality and promising material. Water-based paint - in the shortest possible time will allow you to give the walls and ceiling a finished, neat look. Sometimes after repair stains remain after painting on furniture, clothes, this article is devoted to the problem of how to wash water-based paint after repair.

Water based paint

When removing a stain, you need to understand the composition of the paint. Easily washable is paint based on polyvinyl acetate or simply PVA, a soap solution and a sponge are enough to remove the stain, and paint stains of this type can be easily removed from clothes.

Acrylic water-based paint is wear-resistant to water and powders; to remove it from a hard surface, you will need a spatula or a sharp object for mechanical action and rubbing. If the stain turned out to be on things, we figure out which fabric base is stained:

Dense fabric, for example denim - this type of fabric is resistant to abrasion, you can try to remove the stain with a chemical solvent: white spirit or acetone, then wash it in washing machine in the usual way.
A thin, lightweight fabric without impurities of synthetic fibers, an example of such a fabric can be chintz - the paint can be removed from it by mechanical erasing with gasoline, it is also possible to use chemical solvents, but paper is placed under the fabric when removing the paint, and then it must be washed using detergents. funds.
Fabric based on polyester or other synthetic fibers. To remove water-based paint stains at home from this type of fabric, do not use any solvents, as these agents affect the composition of the fabric. Traces from this type of clothing can be removed with sunflower oil. Paper is again placed under the clothes, and the stains are wiped off with cotton pads dipped in sunflower oil. You should be patient, as the work is time-consuming and troublesome, the paint will be difficult to leave.

These methods will help remove only fresh pollution. To remove dried traces of PVA-based water-based paint, it is necessary to moisten it with plenty of water to soften the dried layers of paint, and then rub it off with a brush, the clothes must first be soaked and washed in the usual way.

Dried stains of paint should be wetted with water and scrubbed with a brush.

Other types of paints

Gouache, watercolor

Dyes of this type are water-soluble and can be easily washed at home. Freshly soiled items can be washed with laundry soap in cold water, and then continue to remove stains with a regular machine wash on the appropriate cycle for the type of fabric.

To remove stains of gouache with an adhesive or oil base, a solution is prepared from ammonia and oxalic acid in proportions of 1:1, in which clothes are soaked for 30 minutes.

Oil paints

freezing oil paints, form a dense crust on the surface, which can be carefully removed. We soften small grains of paint with sunflower or olive oil and remove the stain. Grease stains left after the oil are not difficult to wash off in boiling water with dish detergent, it perfectly breaks down fats and there will be no trace of the stain.

acrylic paint

Acrylic paint stains are one of the most difficult to remove, in many cases a stained item can no longer be saved. If the stain is fresh, you can prepare a solution of ammonia, vinegar and salt, take the ingredients at the rate of 1:1:1, apply this mixture to the stained area and leave for fifteen minutes until the solution works, then wash it in the usual way.

Acrylic paint should be rubbed with a mixture of ammonia, vinegar and salt

Conclusion

The beauty of freshly painted walls is sometimes not worth an expensive and beloved thing, therefore, before painting, it is better to use old clothes that, in extreme cases, it will not be a pity to throw away. If the trouble has not passed, and the spots flaunt on a brand new little thing, then be careful with chemical solvents, follow the instructions for use.

Do not use them near fire. In case of contact with eyes, skin, rinse with plenty of water.

Stains that have not been removed at home can be removed using the services of dry cleaning, where the paint is removed competently and without harm to the fabric.
