So my toddler got ahold of several crayons and she must have really leaned into her drawing because dawn soap and scrubbing wouldn't work worth a darn. I got these magic erasers and boy does it sure seem magical. Barely any scrubbing and the crayon was gone. I also used them on my countertop where I spilled some food coloring a few months ago and I thought it stained the countertop forever. I guess I was wrong, because the magic eraser worked! The only thing I noticed is if you scrub too hard, the sponge gets holes in it.
