How to Clean Chalky Walls
Cleaning chalky walls requires specific techniques and materials to ensure you don’t damage the surface. Here are some DIY ideas for cleaning chalky walls:
Technique 1: Dust and Dry Wipe
- Before you start, gather a soft dry cloth or a microfiber duster.
- The right tools will ensure you clean the walls effectively without scratching or damaging them.
- Remove any furniture or objects near the walls to have unobstructed access.
- Cover the floor with a drop cloth or old newspaper to catch any falling dust.
- Begin cleaning from the top of the wall and work your way down.
- This prevents dust and debris from falling onto already cleaned areas.
- Before wiping, check for any cobwebs in the corners or along the edges of the walls.
- Use a duster or a long-handled broom to remove them gently.
- Take the soft dry cloth or microfiber duster and gently wipe the walls in a top-to-bottom motion.
- Use light, even strokes to avoid leaving streaks or smudges on the surface.
- Clean the corners and edges of the walls thoroughly, as dust accumulates in these areas.
- If you encounter stubborn dust or chalky residue, apply slightly more pressure, but be careful not to press too hard, especially on painted walls.
- If the cloth or duster becomes too dirty, switch to a clean one or give the duster a gentle shake outdoors to remove the dust.
- This ensures that you are not spreading dust around.
- If you notice some areas still covered in chalk, proceed with a gentle cleaning method appropriate for chalky surfaces.
- Once you finish dusting, gather the collected dust and debris and dispose of it in a trash bag.
Technique 2: Warm Water and Mild Detergent
- Ensure you have all the necessary items, including a clean sponge or soft cloth, a bucket of warm water, mild dish detergent, or a gentle liquid soap.
- Combine warm water with a few drops of liquid soap or mild dish detergent in a bucket.
- Gently stir the solution to create a soapy mixture.
- Before using the solution on the entire wall, test it in a small area first to ensure it won’t harm or discolor the paint or wallpaper.
- Dunk a clean sponge or soft cloth in the soapy mixture.
- Allow a moment to soak, then squeeze out the excess moisture until it’s damp.
- Clean the walls in small sections, starting at the top and working your way down.
- This approach ensures more thorough cleaning and prevents streaks.
- Apply the dampened sponge or cloth to the chalky areas on the wall.
- Use gentle pressure and avoid scrubbing vigorously, as this could damage the surface.
- Concentrate on areas with visible chalky residue.
- Gently wipe these spots in circular motions to help lift and dissolve the chalk.
- Be cautious not to oversaturate the wall with the soapy solution.
- Excess moisture can cause damage to the paint or wallpaper and might worsen the chalky residue.
- Periodically rinse the sponge or cloth in clean water to remove accumulated chalk and soap.
- Wring out the excess water before continuing.
- If the cleaning water becomes too dirty or soapy, replace it with a fresh batch to ensure effective cleaning.
- After wiping down the walls, use a clean, dry cloth or towel to pat the surfaces dry gently.

FAQ
Why is my wall turning white?
The white appearance on your wall is likely caused by efflorescence, which occurs when water is present in or on building surfaces like brick, concrete, stone, or stucco.
As the water evaporates, it leaves behind crystalline deposits of salts, resulting in the white or greyish tint you see on the surface.
These salt deposits are what create the visible efflorescence effect.
Does chalk fade away?
Yes, chalk art can fade away over time due to exposure to the elements like wind and rain.
However, there are methods to make it last longer.
One effective way is to cover your chalk art with a plastic drop cloth and secure it in place with duct tape.
Doing this protects your drawings from rain and other elements, allowing them to last until a specific festival or event has passed.
