You can use a hair dryer to blow hot, or use soap or toothpaste to clean.
1. Use a hair dryer to blow hot. This effect is very good. It is also convenient at home. Basically everyone has a hair dryer. It can be used for stickers on glass, plastic, wood, and metal. First, use the hair dryer to blow hot and cold back and forth a few times. Next, tear off a small side and slowly tear along the tearing direction while blowing with a hair dryer. The effect is very good.
2. Use soap and a little mixture of ammonia and turpentine to remove a lot of dirt and make the glass surface more shiny (this article applies to ceramic tiles, ceramics, glass, etc.).
3. Apply toothpaste evenly on the surface of the sticker, leave it there for a while, and then wipe it with a soft rag. Sometimes there is more sticker and it is stronger, and it is not removed at one time. Apply toothpaste on the mark again, using the same method, and you can remove the headache-inducing sticker. The principle is that toothpaste contains glycerin, which is a good solvent and can dissolve the ingredients of the self-adhesive.
Extended information:
Self-adhesive, a polymer compound in the chemical field, is made of paper, film or special materials, with a pressure-sensitive adhesive on the back. Silicone protective paper is a composite material of the base paper. The self-adhesive pressure-sensitive adhesive includes base material, tackifying resin, etc. According to the principle of isostructural miscibility of polymer chemistry, an appropriate solvent is used to dilute the base material or tackifier of the self-adhesive so that it can be easily separated from the adhered object.
Principle of cleaning label glue: According to the principle of isostructural miscibility of polymer chemistry, any organic solvent can dissolve the above-mentioned polymer compounds, such as essential oil, alcohol, gasoline, or nail polish dilution Liquids are all organic solvents, and facial creams, facial cleansers, detergents, and hand creams also have the same effect.
