Peel as much of the sticker from the plastic as you are able. Pour a small amount of mineral spirits onto the corner of a clean, dry cloth.
Rub the now damp corner of the cloth onto the sticky residue on the plastic. Rub in a circular motion while applying pressure to the plastic. Continue this step until all sticky residue is removed from plastic.
Moisten a clean, dry sponge with cool water. Rub the area with the sponge for a few seconds to remove the mineral spirits from the plastic.
Dry the plastic by wiping the area with a clean dry cloth.
