How to remove the damaged coating from a stainless steel travel mug

Colorful film coated stainless steel cups, water bottles, canteens, mugs, etc can be damaged by washing them in a dishwasher. Fortunately, this plastic film coating is not functional and can be easily removed with acetone or fingernail polish remover. Remember to be generous with the acetone and let it do the work for you. It took about 10 minutes in total. This one is a Contigo brand travel mug, but should work for most any plastic coated stainless container.
