How to remove enamel paint from Plastic? i.e my USD skates (durable plastic)?

Spray with oven cleaner, wait 15 minutes, rinse with cold water and scrub with an old toothbrush. It won't harm the plastic. May require a second treatment to get all the paint. Make sure you do it in a well-ventilated room or outside, and wear rubber gloves to protect your skin. *Some of the new formula oven cleaners don't work real well........brake fluid will also do the trick, and still shouldn't harm the plastic. *my husband suggests wd-40
