This reminds me of when my brother was a toddler and drew a green line around the entire perimeter of a large living room. There was probably some loveliness to it, but... oof!
I have red Tadoodles (bath tub crayons) stained on the side of the bath tub. I've tried tons of cleanser. Maybe the WD40 will help?
What's the side of your bathtub made of jessacat29?
The real question is it stained, or is there actual crayon residue left to come off?
I might also suggest the baking soda paste that's mentioned, it will have a slight bleaching effect, especially when combined with heat (from say a blow dryer).
windex does wonders!! Thats what i always use.
Apparently tea tree oil and brown bread gets rid of crayon on walls and wall paper
I don't know what it is made of. This house is 50 yrs old and I suspect it's original. I'm going to try all the suggestions, starting with baking soda since I have that on hand. Thanks all!
