how does the treatment workWhy do crayon companies say treating wax stains on clothes by putting dishwashing liquid then washing it?
Because dish washing liquid is a enzyme and it usually works on many stains. But I found that if you scrape as much as possible off first, then get you iron and heat to warm not hot. Take a piece of paper towel and fold it, put it under the stain and put a single piece on top of the stain, and iron gently, that will heat the wax and remove it, make sure each time you change the paper towel so as not to get stains anywhere else. it works, Then wash it with your dish washing liquid.Why do crayon companies say treating wax stains on clothes by putting dishwashing liquid then washing it?
