Streaks on the walls create many problems for us. To remove them, you need to determine the cause of their occurrence. Organic stains are easy to remove. But stains that are the result of moisture and mold will be quite difficult to remove.
Painting surfaces with stains without determining the cause of their appearance does not make sense. If the cause of contamination is dampness in the room, then the walls must be dried before treating it.
Remove stains
The first step is to determine the origin of the contamination. Traces of organic origin are easy to remove. Leak or water stains are more difficult to remove. Each case must be considered individually.
Test the option that suits you best on a small area. The amount of the required composition is easy to calculate. The approximate quantity is usually marked on the container. The products contain acids, so it is important to follow safety precautions. Use gloves, goggles and special clothing.

- Soda ash will help remove old greasy stains. Mix a few tablespoons of baking soda with ½ cup of warm water. Mix well and apply to the stain. Leave for 10 minutes. Rinse off any remaining product with water;
- If none of the options helped remove the greasy formation from the wall, then there is only one solution - re-painting. You will have to paint the wall with the same paint that was originally used for it. It is best to apply the paint in two layers. If the surface is colored, then you need to find an identical color so that the problem area does not stand out.

Removing stains from stretch and plastic ceilings
Due to their structural features, ceilings made of polyvinyl chloride and other polymers are most susceptible to fungal infection. The empty, hard-to-reach space between the ceiling and the film is an almost ideal environment for the growth of bacteria.
As a temporary measure, household laundry bleaches with a high chlorine content can be recommended. These products clean the surface, and their evaporation partially destroys the microflora, thereby slowing down the formation of fungus, but does not destroy it completely. It is advisable to find the strength and means to repair the ceiling in order to get rid of this “neighborhood” once and for all.
Otherwise, polymers are quite unpretentious. They are inert in their chemical composition, which is why they do not absorb most substances that create problems on other surfaces.
How to dry walls?
If the walls are damp, they must be thoroughly dried. This is the main condition for successful repairs. Natural drying of walls is a rather lengthy process. You can take modern methods, mechanical and chemical. We divide them into invasive and non-invasive. A non-invasive method, walls can be dried using special heaters (without exceeding the maximum air temperature of 35°C). It is very important to ensure proper ventilation of the room so that moisture can find its way out of the building. Other non-invasive methods are condensation and absorption dehumidification.
Invasive methods include injections, thermal injections and crystal injections, which is one of the cheapest and at the same time effective. Suitable for drying damp buildings, regardless of the type of material used for their manufacture, as well as the thickness of the walls and their degree of humidity and salinity. Regardless of the extent of the building's dampness, consult well about dehumidification methods with a professional company or simply hire one to carry out the work.
How to remove mold and mildew from a wall?
Stains may appear on damp walls as a result of the activity of microorganisms - bacteria or fungi. Removing dirt from the wall may not be enough. The cause of the infection must be determined. If the mold is the result of poor ventilation, it is quite enough to remove the layer of fungus, spray it with a suitable fungicidal agent, and then paint it with paint that will ideally cover the remaining trace of stains and also protect it from further development of microorganisms. If the house was flooded and the water brought with it spores of microorganisms, this may require the application of fungicides deep into the damaged wall. Only after identifying and eliminating the cause can we begin further work.
When to start painting walls?
Painting the wall
If the walls have been severely damaged and the plaster does not adhere to the base, you should knock off the old layer and apply a new one. However, if the plaster is tightly connected to the base, then you can limit yourself to filling and restoring defects.
Make sure the wall is dry before you start painting. Painting work can begin when the moisture content of mineral substrates (plaster, concrete, brickwork, fiber-mineral boards) does not exceed 3-6%, depending on the material. During painting, the room temperature should be in the range of 5-25°C, and the air humidity should not exceed 80%.
How to get rid of stains on walls?
Antiseptic coating
During the operation of premises, stains often appear on the walls or ceiling. Before you start painting, you need to get rid of them. It is especially important to remove oil, grime and nicotine stains as they weaken adhesion and may cause discolouration. To remove grease, you should use proven and reliable products, for example, paint thinner. You should not replace it with dishwashing liquid, because, as a rule, they contain polishing agents or substances that protect the skin, such as lanolin.
After washing and drying the walls, areas where there were stains should be painted over with special stain-isolating paint.
Cleaning thin wallpaper
If you use water to clean grease stains from thin wallpaper, there is always a risk of permanently damaging the facing coating. Therefore, for thin wallpaper it is better to use dry cleaning methods. These methods include cleaning with gasoline. It is only advisable to use regular potato starch instead of tooth powder.
To deal with mold stains, it is recommended to ventilate the room properly to get rid of dampness. If the stain is constantly growing, you will have to completely re-glue the piece of wallpaper using special technologies.

Stains on vinyl and non-woven wallpaper
Are you tormented by the question of how to remove greasy stains from painted vinyl and non-woven wallpaper? We will help.
If you try to immediately paint over the stain with acrylic, then 99% of the time you won’t succeed, since the greasy mark will easily “break through” through the new layer of paint. The instructions for skilled hands will be as follows:
- — Remove as much greasy trace as possible using detergent,
- — We prime the wallpaper,
- - Paint over the stain.
To remove grease, you can and should use a dishwashing detergent with a similar effect , for example, Fairy or Frosch. Dissolve the solution in water in a ratio of 1 to 8-10, carefully apply to the stain and press for several minutes with a damp cloth. If the grease is deeply absorbed, the procedure must be repeated several times, just do not rub the area of the defect, otherwise you will damage the top layer of wallpaper.
The greasy mark is gone, but there is still a stain from paint damage? Let's move on to the second part of the instructions. Apply a primer, for example, Sniezka or Tikkurila, to the area of the former defect, covering the adjacent areas of the wallpaper. Wait for the primer to dry and apply two layers of acrylic paint to the entire surface where the stain was (at least 4 hours interval). It is advisable to use the same brand of paint as the primer.
If your vinyl or non-woven wallpaper is not painted, then the procedure for removing stains is similar, just be more careful when working with detergent and skip the step of priming and painting the wall.
For a shallow and fresh stain, it is enough to hold the rag with the solution for a minute once, but if the damage has penetrated deeply or has been distressing the eye for a long time, then the procedure can and should be repeated up to 5-6 times.
The effectiveness of this method is 90%, the main thing is not to go into a rage and rub a hole in the wallpaper - this is original, of course, but ugly.
Recommendations
Advice and recommendations from experts will help you cope with the task of removing greasy stains from surfaces as effectively as possible:
- To remove grease, do not use tools with abrasive surfaces, as this may harm the material.
- The choice of cleaning product should take into account not only the type of material, but also its condition.
- Excessively moistening the stain will not help remove it faster, but it can ruin the material itself.
- If there is any doubt about the suitability of using a particular stain remover, it is advisable to test its effect on an inconspicuous area.
- If the stained wallpaper is old, and the grease stains are extensive, then the best option is to replace them, since it is unlikely to be possible to remove large stains without leaving a trace.
- Some stain removers (both homemade and store-bought) have a strong odor, so it is advisable to carry out all cleaning work in good ventilation.

Stains on paper wallpaper
If grease stains appear on paper wallpaper, then there is more work and there is no guarantee of a positive result, because it is not easy to completely remove grease from the fabric and not damage the top layer of wallpaper.
Try using crushed chalk to remove greasy marks. Limestone is crushed to a powdery state, poured into a damp cloth and pressed onto the stain. The procedure may have to be repeated many times, but if the stain is not old, then there is a high probability that the chalk will draw out the grease.
For the freshest stains, you can use gasoline or acetone, which is moistened with a clean (!) rag and applied to the defect. Gasoline breaks down fat, but the smell can remain in the apartment for a long time, so start with chalk and move on to solvents only as a last resort.
Detergents are not used when removing stains from paper wallpaper - it will quickly soak the material and even after removing the grease, a mark will remain on the wall.
Some try to apply toilet paper to the stain and iron it with a very warm iron, but this method did not work for us - the standard approach helped: chalk, primer, repainting a section of the wall.
Answers on questions
Can stains be removed using a salt cloth and an iron?
If the stain is not old, it is possible, but in this case it is also possible to get rid of the wallpaper - it can simply come off the wall.
If you paint over a stain three or four times, will it disappear?
No, the greasy stain will not disappear - the grease will easily break through the paint, and perhaps it will only fade. First you need to remove as much fat as possible, then prime, then paint.
