After graduation finishing works stains and streaks often remain on plastic windows from building mixtures. The mounting foam must be cut off and the remnants removed with Dimexide, White Spirit or a special wash. The protective film is removed with a scraper and a building hair dryer, and the remaining glue is dissolved with alcohol. Paint, putty and whitewash can be cleaned with a spatula or use household chemicals. We will tell you how to clean windows after repair and remove scratches from plastic profile.

The finishers have finished their work, but before the house shines with cleanliness, you need to remove construction debris and wash all surfaces from paint stains, putty and lumps of mounting foam. First, let's take care of the windows: first of all, we will remove the protective film, usually this is done in one movement, but if the windows have been installed for a long time, and no one has removed the film, then you have to tinker.

Protective film

Some owners neglect the instructions and do not remove the protective tape, explaining that the repair has not yet been completed and the plastic profile must be protected from stains and building dust. This is certainly true, but over time, the glue changes its properties and the film firmly “sticks” to the frame. It is better to remove it immediately and stick masking tape, which is easily removed and protects against dirt just as well.

If you did not know this, and the film managed to stick tightly, then use one of the suggested means:

Construction hair dryer and scraper for ceramic-metal stoves. It is necessary to heat the film and remove it with a scraper for cleaning metal-ceramic plates.
Scrape off pieces of film with a blade or a clerical knife, and erase the rest with an eraser. It will take quite a long time to clean, but the result will not disappoint you.
If the film has crumbled, then washing it off can be quite difficult. Useful for work White Spirit or industrial alcohol. Apply the product to the pieces of film, wait a few minutes and rub well with a stiff bristled brush ( metal can not be used!)
Another way to remove small pieces is to stick a wide adhesive tape over it, press it well, smooth it, wait an hour and tear it off along with the stuck pieces of film.

Attention! Apply " Cosmofen"and similar products of other brands only as a last resort, if household chemicals were powerless. Some types of plastic may change color from solvent exposure or lose their gloss.

Cleaning up putty and plaster

During clearance window opening and wall putties, building materials often get on glass and frames. Plaster is gypsum, cement or lime. Regardless of the composition, it is washed from the plastic profile with a damp cloth. If it has had time to dry, then use a dry rag or spatula, depending on the degree of contamination. In order not to scratch the plastic, the sharp edge of the spatula is wrapped with rags and pieces of plaster are cleaned off, cutting it off at the very profile.

Sealant (silicone)

If it hit the windows silicone sealant, there is nothing wrong with that. Just wait until it dries, pick up the edge with a spatula, grab it with your fingers and gently pull until it is all in your hands.

Whitewash

Dry whitewash from glass and plastic is easily wiped off with a dry cloth, using a wet rag, you will only disperse the dirt and wash stains and smudges for a long time. After you remove most of the whitewash with a dry cloth, you can start cleaning the window. The plastic profile is washed with soapy water, and the glass with a window cleaner or homemade detergent composition(for 2 liters of water 1 tablespoon of ammonia or 2 tablespoons of vinegar).

Things are not so good with lime whitewash, it will not just fall behind. It can be removed from glass with a blade or a clerical knife. In order to wash off lime from PVC windows, use one of the suggested means:

After the whitewash is washed, the surfaces are degreased with dishwashing liquid. Lacquered furniture do not degrease, but polish with a soft cloth.

Wallpaper glue is easily washed off with warm water.

Mounting foam

If the team was not very careful, then after they left you may encounter another problem: dried mounting foam on the profile, window sill and glass. If the foam has frozen in a piece, then it can be scraped off with a spatula, and the remaining trace can be washed off with the help of improvised means. How ? We will briefly touch on this issue, for more details, click on the highlighted fragment.

Apply the wash only with a white cloth, otherwise the dye will dissolve and be absorbed into the plastic, it will not be easy to wash it off. But it is better to let the foam harden and remove it mechanically.
« Dimexide» – pharmacy remedy, which is used experienced builders to remove traces of mounting foam. It is necessary to cut off the main part of the piece with a blade, moisten with dimexide cotton pad and rub it well, put the disk on the stain and leave for 5-10 minutes. The foam will soften and peel off the plastic easily.
You can use a home-made "wash", for this you need to mix 10 grams of acetone and solvent A-649, 20 gr. vinegar essence and 50 gr. liquids for washing construction guns. Installers claim that this composition dissolves any brand of mounting foam.

Remove scratches

If scratches appeared on the plastic during the repair process, then a solvent is useful in this case. Kosmofen-5”, about which we promised to tell in more detail. It is used by professional installers to polish the profile, remove scratches and scuff marks.

There are three groups of products for plastic restoration: liquid plastic, cleaner and polish.

Liquid plastic is a self-hardening mass, which is filled with deep scratches, after which the surface is polished. It is also used for bonding plastic surfaces. It happens different colors.

Unlike liquid plastic, the cleaner does not fill the scratch, but dissolves the PVC. After you have applied the solvent, you need to carefully level the surface and polish.

Polish for plastic contains substances that fill small scratches and scuffs, creating the illusion of newness and gloss.

Get ready for work:

A few white rags, colored rags shed from cleaner components, and instead of removing scratches, you get an indelible color stain. When choosing a rag, check to see if it leaves a lint.
Chosen remedy.
Sandpaper No. 400 or 600.
Putty knife.

Before starting work, prepare the surface: wash with soapy water and degrease with alcohol or window cleaner.

Sand the scratched area with sandpaper, perhaps this will be enough.

If the scratch is very deep, then take a spatula, apply a little liquid plastic to the edge, and firmly pressing the spatula to the surface, fill in the scratch. Wipe off the rest of the glue with a rag. You need to act quickly - the plastic hardens in 60 seconds. Next, you need to apply on a piece of fabric " Kosmofen-20» or gently buff the affected area.

If the scratches are not so deep, then use a plastic solvent " Kosmofen-5". You need to apply a little product to the surface, as soon as the plastic softens, it is gently smoothed out with a brush to fill in the scratch. After hardening, the restoration site is polished soft cloth dipped in " Kosmofen-20».

Polish is used to remove minor scratches and scuffs. Soak a soft cloth in the product and polish the damaged surface in a circular motion.

We want to warn readers that: the work of restoring plastic is quite painstaking and requires certain skills. The quality of plastic varies greatly depending on the manufacturer, an inexperienced person may make a mistake in choosing the means or in the process of work. Therefore, we still recommend entrusting the removal of scratches to the specialists of the company where you ordered the windows. The cost of such services is unlikely to be higher than the cost of a repair kit.

If you don’t know how to clean plastic windows after repairs in a new building, but would really like to know, then this article is for you.

Preparatory stage

Washing windows after repair is carried out in several stages. The first is the preparation and removal of serious contaminants. We list the most common types of pollution and how to eliminate them.

Glue spots. They often remain after making drywall slopes, wallpapering walls or foam boards on the ceiling. To get rid of them without damaging the surface of the frame and glass, use products based on special solvents. If they are not there, then heat the adhering drops of glue with a hair dryer and carefully remove them with a spatula.
Cured plaster. Wet it with water and scrape it off with a spatula.
Mounting foam. It should be removed carefully so as not to violate the integrity of the window. If the foam does not give in, then treat it with acetone thinner. To do this, soak a microfiber cloth in it and apply it for a few seconds to the place where the foam has eaten. As soon as the foam gets wet, remove it with a rag.

window washing

When traces of building materials in the new building are removed, it's time to start cleaning the plastic windows. You should start with glasses, using purchased or self-prepared products. You need to wipe the glass with a wet cloth and wipe it dry, then do the same, only using a cleaning agent.

Folk remedies self cooking. To wash well window panes, it is not necessary to buy expensive branded formulations. Can cook effective remedy and independently. To remove stains, you need to mix the following ingredients:

technical or medical alcohol - 50 ml;
9% table acetic acid - 50 ml (if there is no acetic acid, then a pinch of citric acid or juice of 3-4 lemons);
half a liter of water;
corn or potato starch (tooth powder or chalk) - 1 tbsp.

Mix all the ingredients, spray on the glass with a spray bottle and wipe with a napkin. To clean the glass of dried dust or paint stains, add liquid soap or dishwashing detergent to the vinegar solution.

Ready-made purchased chemicals. The advantage of such funds is that you take and use. No need to mix anything and look for a spray bottle. To remove traces of contamination, the solution is sprayed onto the window, after which it is immediately wiped dry. The following glass cleaners are available on the market:

"Help";
"Mister Muscle";
"Wedge";
"Second".

Frame washing

After the construction dirt is removed with soapy water, the glass is cleaned, and the protective film is removed from the frame, it's time to start washing the window frame. For this purpose in 3 liters warm water dissolve 1 tbsp. liquid dishwashing detergent and a grated third of a piece hard soap. When the solution has acquired a homogeneous consistency, moisten a soft cloth in it and proceed to wash the window frame. If there is no desire to prepare the mixture yourself, you can use the following ready-made compositions:

"Domestos";

"M. Proper.

In addition to traditional products, other preparations have proven their effectiveness in washing plastic frames. Among them, a solution of ammonia (25 ml per liter of warm water) can be noted. It is good to use after products that sometimes leave streaks on the glass. A 9% solution of table acetic acid, kerosene and even nail polish remover make it easy to clean stubborn paint stains from a plastic profile.

Washing window sills

To wash plastic window sills after repair, you will need a double-sided sponge, hard on one side and soft on the other, or a rag. An excellent option in this case would also be a melamine sponge, which is made from a special resin that demonstrates good abrasive qualities when cleaning.

To wash the window sill from grease, a dishwashing detergent is well suited.

A more serious problem is the protective film, which is well removed when fresh, and eventually sticks tightly to the window sill. In this case, it is necessary to heat the film with a building hair dryer and carefully pull it over the edge so that it does not break. You can also try sticking tape on top of the film and tear it off.

Another serious contamination is dried primer stains, against which solvents and soapy water are powerless. A fresh primer can save the situation, which is applied on top of the stain, held for a couple of minutes and washed off with a rag.

No less difficult are attempts to wash the plastic window sill from traces liquid nails. If they have a water base, then you can try to heat the pollution with a building hair dryer and carefully work with a spatula or sponge.

Restoration of a plastic window sill after stubborn lime whitewash is carried out aqueous solution vinegar or salt, after which the residue should be removed with a clean cloth.

In order to achieve a good result and flawlessly wash window frames and glass from the remnants of construction debris, certain rules and precautions should be followed:

To wash windows, use rags made of non-shrinking soft fabrics. Otherwise, the microvilli stick to the glass, making it difficult to clean. Flannel or cotton fabrics, paper and microfiber napkins are best suited for such purposes.
When using cleaning chemicals containing alcohol, wear gloves. Otherwise, damage your skin. In some cases, it is necessary to wear a protective mask so as not to inhale caustic fumes.
Some cleaners contain coarse abrasive particles. When intensively rubbing them into glass, window sill and frames, there is a risk of scratching the latter. Therefore, such substances should be used with caution.
It is necessary to wash windows in the correct sequence: first of all, the outer part, which “looks” into the courtyard, then the window sill, mechanisms, frame. It is best to carry out this procedure after the repair is completed in the evening or early in the morning, when the sun's rays do not fall on the window.
Upon completion of the procedure, the windows and the room itself should be vacuumed, removing particles of soil, cement and building dust that have accumulated there.

To achieve the best result, you should strictly adhere to the above rules and recommendations on how to clean windows after repairs in a new building.

During repairs in a new building or during the installation of windows, it is very difficult to keep frames and glass clean. And washing them from construction dirt is also more difficult than from ordinary household dirt. But for each type of pollution there are cleaning products. Do you want to know which ones? I'll tell you about this.

Film and tape marks

All manufacturers recommend taking protective film glued on plastic windows after their installation. But this is not always possible to do on time. And when repairing frames, they are often pasted over with adhesive tape or mounting tape to protect them from dirt.

Over time, these films firmly “stick” to the surface, and it becomes problematic to clean the plastic from the glue.

The first thing you can try to do this is hot water and the hard side of a dish sponge. Before washing the plastic on the windows with any other drug, try this option.

In case of failure, they will come to your aid:

Image	Tool name
	Undiluted medical alcohol, as well as vodka or cologne.
	Nail polish remover. Better one that does not contain acetone.
	Tea tree oil.

Scotch stains, as well as stains from stickers on glass, are soaked with any of these liquids, after which they are scraped off with a plastic spatula.

Cement

When plastering and leveling walls, protect plastic frames and double-glazed windows from spraying the solution is quite difficult. How to clean them from hardened cement. Try one of the following methods.

Method 1 - special tools

If you need to get the result quickly, and the price of the product does not really matter, buy special preparations designed for cleaning different surfaces from cement. For example:

ATLAS SZOP;
Cement N Concrete Remover;
Baugerätereiniger 81.

All of them are available in the form of a spray, which is sprayed onto a contaminated surface. After the specified time, the dissolved or softened solution is washed off with a rag.

The main thing is that the product does not contain caustic acids in its composition. which can damage the plastic. Therefore, the instructions for use are required to read before buying.

Method 2 - Comet

Another effective window cleaner mortars is considered a Comet thick gel for plumbing.

You can clean plastic windows with it like this:

Apply gel to stain. If it is a vertical surface, then you will have to apply several times.
Wait until the cement becomes loose and soft.
Remove it with a damp cloth.
Repeat if necessary.

But before cleaning windows after repair from dirt and grout, vacuum or brush them to remove badly stuck pieces and avoid unnecessary work.

Method 3 - acetic acid

If you don’t have the means described above and you have nothing to clean plastic windows with, use vinegar essence, diluting it a little with water.

How to clean windows with vinegar:

think about protective equipment - put on rubber gloves and a gauze bandage.
Dilute the acid with some water.
Soak a rag in the solution and saturate all stains liberally with it..
After a few minutes, try wiping them off. with your own hands.
If the result is unimportant, sprinkle baking soda on a rag with a solution so that it gets wet, and rub the stained places.

In the same way, you can wash liquid glass. But you should try to clean the frames and glass from it immediately, using just hot water. Otherwise, it will react with the surface, and it will become very difficult to get rid of the stains.

Mounting foam

To seal the window, foam is blown into the space between the frame and the opening. Increasing in volume, it often stains plastic.

Do not try to wash it with water, even fresh - it is useless. And all kinds of solvents or means with which they are washed mounting gun can corrode plastic. How to be?

fresh footprints it is easiest to remove from mounting foam with Cosmofen. It is this cleaner that plastic window installers use. It comes in three types (see photo). The higher the number, the weaker the remedy.

Dried foam won't take any detergent, and Cosmofen may not help. In this case, Dimexide will solve the problem. This medication is a good solvent, so you need to work with it with gloves. The undiluted liquid is applied to the stains with a sponge or cotton swab, and after a few minutes it is washed off with a damp cloth along with the remaining foam.

Dye

You can not break your head about how to wash the glass - any solvent designed for the type of paint that needs to be removed will do. With plastic it is more difficult, the solvent can damage it:

If the paint is on water based , you can try to clear it with hot water, soaking the splashes and scraping them off with a scraper.
From other types of paint and get rid of the primer with turpentine.

But try not to use knives, blades and metal spatulas - they leave scratches on the surface. The scraper material should be harder than the dirt, but softer than the plastic itself.

Polish is always found in the set of care products for plastic windows.
