Arya decided to try out some of her artistic abilities on my backdoor, window, and my TV room window. I had always heard to get those Mr. Clean eraser pads to remove anything off of your walls. I went to the Dollar Tree and bought their version on the cleaning pads (2/$1). It took the crayon right off of my metal door and the windows. It left a little brown residue from the crayon, but I wiped it clean with a wet paper towel. I definitely would recommend this product!
