Tips for removing gouache stains
Gouache is an adhesive-based paint, which allows it to harden faster and be absorbed into the fabric with lightning speed. It will be much easier to remove traces of such paint from synthetic paints than from natural fibers. Natural fabric has a higher level of hygroscopicity, so any stains are eaten into it at high speed, and it will not be possible to get rid of them through regular washing.
In addition, there are a few simple rules that are worth remembering:
- when removing gouache from any fabric surfaces, do not use hot water, it will have the opposite effect and the paint will penetrate even deeper into the fibers;
- before using any product, test it on a small, inconspicuous area of fabric and watch the reaction;
- If you are removing a stain from a piece of clothing, be sure to wash the item completely afterwards.

How to wash gouache from various surfaces

How to remove gouache from clothes
Most often, during the painting process, gouache ends up on clothing and leaves very noticeable stains that are reluctant to wash off. There are several proven methods to remove gouache stains from fabrics and remove stubborn stains from clothes:
- Laundry soap. Immediately after the stain appears, clothing should be removed and soaked in cold water for several minutes. After this, the dirty area is generously soaped with natural laundry soap and left for 20 minutes so that the soap penetrates deeper into the fibers of the fabric and dissolves the dye. Then the soap and dirt are washed off with cool water, and if the stain does not come off completely, the procedure is repeated.
- Oxalic acid and ammonia. Fresh contamination can be easily removed with a mixture of ammonia and oxalic acid. Both ingredients are mixed in equal proportions, the clothes are soaked in cold water, and then treated with the prepared cleaning agent. The clothes are left for half an hour, after which the acid and ammonia are washed off in cool water. To wash gouache from a white shirt or colored items, you will finally need to load the clothes into an automatic washing machine with powder.
- Petrol.
Old, ingrained gouache is unlikely to succumb to laundry soap or ammonia. To wash gouache from clothes, in such cases you can use purified gasoline. A cotton pad is dipped into the chemical, the dried stain is thoroughly blotted with it, and then the fabric of the clothing is rubbed for several minutes, directing movements from the edges of the stain to its center. Then the gasoline is washed off, the clothes are washed again in a solution of laundry soap, and at the final stage they are sent to the washing machine. The only drawback of this method is that it cannot be used for artificial fabrics; synthetics will deteriorate from such treatment. Attention! Before removing gouache stains from fabric, aggressive household products should be tested on a small area of fabric in an inconspicuous place. Household solvents, acids and alkalis can negatively affect the color of clothing and leave unsightly stains.
How to remove gouache from carpet
Gouache often gets on the carpet pile, and in this case it is more difficult to remove paint than from clothes; the carpet cannot be washed entirely and is subjected to intense mechanical stress. However, there are still ways to restore carpet cleanliness:
- You should try to wash off fresh gouache on the carpet with cold water. First, the top layer of paint is removed by hand, blotting the gouache with a sponge or rag. After this, the carpet is lifted, a basin or wide bowl is placed exactly under the stain and the stain is carefully poured with cold water. You need to wait until the carpet is wet through. After treating a fresh stain with water, it will become much weaker, or even be completely washed out of the pile.
- If you can’t wash the stain with water, you can use regular laundry soap. The stain soaked in water is rubbed with a bar, left for 10 minutes, and then the pile is treated with a brush, trying to completely remove the dirt. After this, the carpet is again treated with cold water to remove any remaining gouache and soap.
- If laundry soap has no effect, you can use more aggressive agents, as in the case of clothes. Gasoline in combination with table vinegar gives a good effect - purified gasoline and slightly heated vinegar are combined, mixed and soaked in this solution on a stubborn stain for 15 minutes. After this, the carpet is washed very thoroughly with cold water to eliminate the pungent odor. Vinegar and gasoline help remove even very stubborn and long-dried stains and remove gouache from the carpet.
Specialized chemicals for carpets and special stain removers have a good effect in the fight against gouache on the carpet. The substances are diluted according to the instructions or simply applied to the spot, and after 15-20 minutes, washed off with water. Carpet cleaning products are designed to remove the most difficult stains, and there are usually no problems in removing gouache from the carpet.
How to remove gouache from plastic
Due to its hard structure, plastic absorbs dirt much worse than clothing or other textiles. It is very easy to remove fresh paint from a plastic surface; just wipe the stain with a damp sponge or rag so that not even a trace remains of it.
However, if a gouache stain is not noticed immediately, it can even be absorbed into a plastic window frame, into a table surface, or into a bathtub cover. Then it will be more difficult to wash it, you will have to use rather aggressive means:
- The universal solvent White Spirit works well for removing gouache from plastic. Dip a small cotton swab in the chemical and vigorously rub the stain until it disappears completely. After this, the plastic will need to be washed with a clean, damp sponge to remove the odor.
- Another reliable remedy for gouache is brake fluid, which can be found in the stocks of car enthusiasts. Moisten a rag or cotton pad with the product, thoroughly wipe the contaminated area, and then wash it off, the stain disappears without a trace. Considering the high toxicity of brake fluid, the surface after it must be washed very thoroughly with clean warm water; among other things, this will prevent yellowing of the plastic.
- Caustic caustic soda, which is diluted with water in equal proportions, helps remove dried paint that has become strongly absorbed into the plastic surface. The solution is applied to the contaminated area and left for several hours - after some time, the dried paint will begin to bubble and come off. You can wash it off faster if you gently rub the treated area with an old toothbrush.
Advice! When working with caustic chemicals, you can only wear rubber gloves; it is advisable to wear a face mask or respirator - toxic fumes can harm your health.
How to remove gouache from wallpaper
If gouache gets on walls covered with wallpaper, then success will largely depend on the material:
- It is quite easy to remove traces of gouache from vinyl and non-woven coverings. First, wipe the stained area of the wall with cool water, and then apply a small amount of baking soda. The wallpaper should be rubbed with a sponge or soft brush and leave the cleaning agent for 10-15 minutes, and then remove its residue with a damp cloth. Since vinyl and non-woven material absorbs dirt poorly and also has grease-repellent properties, gouache usually does not leave even faint traces.
- It is much more difficult to remove gouache from paper wallpaper, or rather, it is simply impossible. The paper covering cannot be wetted with water or rubbed with a brush, as this will deteriorate it and lose its attractive appearance. The best way to remove gouache on paper wallpaper is to simply replace the stained area with a fresh piece of the same wallpaper. A small “patch” is cut out from the remnants of the roll, applied to the dirt, and then both old and new wallpaper are cut through with a sharp knife. The stained piece is removed and thrown away, and new wallpaper is evenly glued to the exposed section of the wall, trying to align the “patch” exactly along the edges with the main part of the wallpaper.

How to remove gouache from linoleum
You can wash gouache from thick linoleum in much the same way as from plastic:
- If the paint is completely fresh, it is enough to wipe the floor covering with a wet sponge and soap or detergent, then there will be no dirt left on the floor.
- Against dried stains, you can use vegetable oil, which easily dissolves the structure of even stubborn stains. Treat the gouache with oil, leave for about half an hour, and then wipe the area with a soft brush or rough sponge with detergent and wash the floor with clean water.
- If the dirt is very persistent and the methods listed do not help to remove it, you can use any solvent or acetone. Soak a cotton pad in the chemical composition, wipe the stain and leave the solvent for a few minutes, after which the stain is washed off with water.
Advice! Before treating gouache on linoleum with a solvent, you need to apply a little product to an inconspicuous area of the floor covering and see if the solvent will spoil the color and pattern of the linoleum.
How to clean gouache from a sofa
If gouache was accidentally spilled on a soft sofa with fabric upholstery, then you need to clean the furniture in much the same way as clothes or carpets. Most often, laundry soap is used - foam is applied directly to the dirt, the problem area is lightly rubbed with a brush, and then the remaining soap is thoroughly washed out of the fabric fibers.
If soap does not help wash the sofa, you can use gasoline mixed with vinegar or ammonia against an old stain. They will help restore the sofa upholstery to a clean and fresh look.
