How to clean painted walls to remove grease and grime stains
Cleaning eraser sponge
1. First, mix a few drops of liquid dish soap with warm water in a spray bottle. Dish soap is specially formulated to cut through grease and is not too harsh to use on painted walls.
2. Use a non-abrasive sponge and do a spot test on the stain first before you start cleaning the entire area. This is to see if the cleaner will work without taking off the paint.
3. For tougher grease stains, you can mix baking soda with warm water until it forms a paste. Carefully work the paste formula into the wall stain, taking care not to scrub the area too hard. This will only make the stain worse.
4. Then, wipe away the formula residue with a clean, damp microfiber cloth. It’s best to use white, lint-free cloths to prevent the fabric color from bleeding into your wall.
How to clean painted walls to remove coffee stains and other spills
1. Make up a natural multi-purpose cleaning solution by stirring one teaspoon of liquid dish soap into a quart of warm water. Follow this by adding a ¼ teaspoon of white vinegar.
2. A top trick is to apply the solution to the stain with a soft-bristle brush.
3. Do a spot test first before working the solution into the stain. Gently scrub in side-to-side movements without putting too much pressure on the area.
4. Wet and wring out a paper towel to rinse out the cleaner. Once the coffee stain is removed, wipe off the surface with a dry cloth and leave to dry.
How to clean painted walls to remove pencil marks
1. First, try to remove the marks with a brand new pencil eraser or art gum eraser. Focus specifically on the marks so you don’t rub an entire area and risk damaging the paint.
2. If this doesn’t work, you can try to gently rub the mark with a cleaning eraser sponge (opens in new tab). Cleaning eraser sponges are non-abrasive and designed to remove pencil marks from your wall.
3. Another easy method for pencil stains is to dip the corner of a damp cloth into baking soda and dab along the mark.
4. Repeat until the mark is removed before using another clean damp cloth to wipe the baking soda off.
5. Another trick is to apply a tiny amount of daily white toothpaste onto a soft cloth and rub gently on the pencil mark. Similar to baking soda, toothpaste is a mild, natural abrasive that can help to remove pencil stains.
How to clean different types of painted walls
How to clean your painted wall depends on the type of finish it has. Flat finishes such as matte, and eggshell paint are less durable to clean, so avoid using harsh chemicals or degreasers that may strip the paint. Gloss or semi-gloss paints are highly durable and can cope with a mild degreaser. Latex paint simply needs warm water and a non-abrasive cleaning solution.
