A method of removing paint from a plastic substrate at least partially coated with a paint coating by: providing at least one plastic substrate at least partially coated with a paint coating; providing a kit for a user to utilize to remove paint from the plastic substrate, which is at least partially coated with a paint coating; immersing the at least partially coated plastic substrate into first mix of components by the end user wherein the first mix of components further comprises water when the at least partially coated plastic substrates are immersed into the first mix of components; and rinsing the plastic substrate with water. The immersing and rinsing steps remove the paint coating from the plastic substrate. The kit includes: a first mix of components that includes: at least one aromatic alcohol; an alpha-hydroxy acid; an anionic surfactant; 2-mercaptobenzothiazole or salts thereof; and an arene; and instructions instructing an end user to remove paint from the plastic substrate using the first mix of components.
