Crayon
Remove Crayon on hard surfaces including walls and woodwork: Most children's crayons are now washable. Dampen a cloth with CleanEz. Blot, wait 15 minutes and blot with vinegar and water. Toothpaste is a mild abrasive and sometimes works on crayon marks.
If the crayon does not respond then it must be dissolved. Use the CleanEz full strength, wipe on wait 5 minutes and rinse with plain water.
