The correct way to remove paint from vinyl (jewelry, clothing, or other materials) is to use paint thinner (and for sturdy fabric) or a similar product. The thinner you use, the better the chances that the paint can be removed. Paint thinner will literally melt the paint off of the vinyl. However, once you start melting the paint, it will also start to melt the vinyl. Goof Off is a solvent that softens vinyl. It doesn't remove paint from vinyl as well as paint thinner or other products, but it does work. Goof Off does not work well on paint that has been on vinyl for a long time. It is a product for removing fresh paint only.
