In fact, alcohol, gasoline or nail polish thinner stored at home can easily and thoroughly remove these stickers. There is another thing that can achieve a certain effect, and that is hand cream. Methods: Tear off a layer of paper on the surface of the label, smear it with alcohol or gasoline, then rub it on the surface by hand to make it fully saturated with adhesive, and finally wipe it off with a cloth. Principle: Glue commonly used for labeling belongs to polymer compounds in the chemical field. Alcohol, gasoline or nail polish thinner are all solvents, which can dissolve polymer compounds. Nail polish thinner is more soluble than alcohol and gasoline. At present, many hand creams on the market contain glycerol, silicone and natural active agents. Glycerol and silica gel have a moisturizing effect on the skin, and both can dissolve the adhesive. Note: There are many kinds of self-adhesive in the market, with different chemical compositions and different adhesive properties. Therefore, hand cream is not a perfect choice.
