Cleaning the house is tiring. Furthermore if your walls are full with marks from our children. But I have few tips to clean it up easily.
Our walls are a painted, textured sheet rock and we have several "artists" in our family.
Prepare these stuffs :
1. Using a soap filled steel wool cleaning pad
2. a little water
3. gentle circular motion
Then scrub the marks until they disappear.
It even works to at least drastically lighten (if not totally remove) permanent marker!
Any remaining permanent marker will now be easily covered by touch up paint, even white.
Do you want to try it?
