1. Almost all the registered trademarks, commodity bar code and price labels attached to commodities are attached with self-adhesive fingers. When these labels are removed, sticky self-adhesive marks are often left. At this time, you can use an eraser with good quality for students, and patiently and carefully wipe the adhesive parts, so that you can leave no trace.

2. In fact, alcohol, gasoline or nail polish diluent stored at home can easily and thoroughly remove these stickers. There is another thing that can also achieve a certain effect, and that is hand cream.

method: tear off a layer of paper on the surface of the label, smear it with alcohol or gasoline, and then rub it on the surface by hand to make it fully saturated with adhesive, and finally wipe it off with a cloth.

principle: the glue commonly used for labeling belongs to polymer compounds in the chemical field. Alcohol, gasoline or nail polish diluent are all solvents, and these solvents can dissolve polymer compounds.

The solubility of nail polish diluent is stronger than that of alcohol and gasoline. At present, many hand creams on the market contain glycerol, silicone and natural active agents. Glycerol and silicone play a role in moisturizing the skin, and both of them can dissolve the adhesive. Therefore, as long as you use these items skillfully, you won't worry about these labels making beautiful things dirty.

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. At the same time, not all hand creams contain glycerol, silicone and natural active agents. Our idea is limited to the case that you don't have alcohol, gasoline or nail polish diluent. You can try hand cream.
