Well my so figured out how to color on the walls when I was folding laundry and I tried every cleaning product I had in my arsenal until I went and purchased this product. It is the only thing that got the crayon off the walls without taking off the matte paint with it! Worked perfectly! I'll keep some on hand just in case my son finds a rogue crayon and takes on more walls again! Great great prpduct, saved me from repainting!
