For the self-adhesive marks on the surface of hard objects, we can apply grease-free nail polish remover to the surface of the objects, and then gently wipe them with a soft cloth; These traces can also be removed with industrial alcohol or gasoline. If these stickers get on the skin, you can also use lemon juice to remove them.
In addition, hand cream can also achieve the effect of removing self-adhesive. Hand cream contains a lot of water (generally above 7%) and a certain amount of surfactant. Surfactant has good wetting, penetrating and dissolving ability, and can quickly penetrate between the adhesive and the surface of the object, thus achieving the purpose of cleaning. You can also find that some similar products, such as face cream, facial cleanser and detergent, have the same effect.
