Check out the step by step for daily, deep cleaning, wallpaper, masonry and how to remove stains:

Daily cleaning

Daily you can already have some care that will prevent the walls from getting dirty, making it easier on the day of heavy cleaning. Realize some risk done by children, clean immediately with water and neutral detergent or other specific products (check more on the topic stains).

The same holds true for liquids that are dropped on the walls and any signs of mold you notice. The sooner you clean, the better. If there was no accident, basic cleaning can be done with a damp cloth and water and mild detergent.

No need to get soaked, just moisten. First wipe a broom wrapped in a dry cloth to remove the cobwebs. Then wrap the damp cloth on the broom or squeegee and run the length of the wall. Leave the room airy with windows and doors open to ensure that the wall dries well.

Deep Cleaning

For deeper cleaning, start by removing any stain. Check out the "stains" topic below to see what you can do to make it easier. Then prepare a bucket with water and detergent and soak a sponge in the solution.

Rub all over the wall. Unless paint used for paint is water based. In this case it is advisable to gently sponge, without rubbing or squeezing. If it is very dirty and has not been painted with water-based paint, put a cup of white vinegar in a bucket of warm water, soak the sponge in the mixture and pass on the wall.


Wallpaper also needs cleaning, but wager on substances that do not damage it or cause it to peel off the wall. First remove the dust with the help of a vacuum cleaner or a broom wrapped in a cloth.

Then prepare a bucket of warm water with a little detergent. If the coating is vinyl can use warm water and white vinegar. Dip a soft cloth or sponge into the mixture and gently rub the wallpaper.

Both blends help remove stains and mold the wallpaper.


If the wall has not yet been painted and is only masonry, you should start cleaning by wiping a broom all the way to remove any dirt. Prepare a mixture of water and detergent and start washing the wall from top to bottom, thus avoiding water stains.


The stains can be the big problem of the walls. Most of the dirt claims on this piece of the house are tied to fat, blood marks and the famous scratches done by children.

For each type of stain is indicated:

1. Hand marks

Hand marks, when caused by ordinary dirt (hands dirty with dirt or dust, for example) can be resolved with baking soda. Just put a little on a dry sponge and pass on the wall.

2. Fat

To remove fat stains you should prepare a paste of baking soda. Just mix it with a little warm water to get the paste. Apply on the stain and rub with the help of a soft cloth or sponge. Both dry. If the fat stain is more resistant, prepare a mixture of vinegar and water and rub in that part of the wall.

3. Pencils, chalk or pen

If children have been showing off their talent for the arts using the wall as canvas, you can solve this problem easily. For the pencil, an eraser already helps, but for chalk or pen, toothpaste, moist handkerchief or a damp sponge with a little baking soda.

4. Pen

The stains were caused by ballpoint pen? Pass acetone or shaving cream in the region. Scrub a little and that's it, the wall will be clean.

5. Mold

Water and soap is not a useful blend to get mold out of the wall. Instead, take a spray bottle and put a quart of water. Then add a tablespoon of vinegar. Spray on the stain, let it act and wipe with a cloth to remove the mildew.

6. Blood

Bloodstains should be cleaned as soon as they happen. But if you did not notice you take a flexible rod, soak in the hydrogen peroxide and apply it on the dried blood on the wall. Do not scrub and do not use cloths or sponges to spread the stain.

7. No switch stains

Switches may also get stained, but unlike walls, you can not use water or any liquid product to clean them. Apply a little baking soda and rub with a dry sponge.

Keeping the house airy is a very important tip. Especially for those who have been dealing with mold on the walls. The fungi that cause mildew like humid environments, so try to keep the house always airy with doors and windows open.
