In fact, the problem still comes back to how to clean the stickers. Here are some practical methods.

1. Use a hair dryer

Principle: Rely on heat to remove self-adhesive.

Method: Use the hot air setting of a hair dryer to blow directly with hot air at a distance of about 10cm from the sticker; after blowing for a while, slowly peel off the sticker while blowing.

Advantages: easy to operate, good effect, quick results.

Disadvantages: Not suitable for soft plastics that are not heat-resistant. High temperatures can easily deform objects.

2. Use edible oil

Principle: principle of similarity and compatibility.

Method: Apply cooking oil evenly to the place where the label is attached. After 3 to 5 minutes, you can slowly peel it off from the corner of the label with your hands, so that no trace of the label will be left.

Advantages: Good decontamination effect on glass, stainless steel and other hard objects.

Disadvantages: The effect of removing stickers from other objects is not good.

3. Use alcohol

Principle: principle of similarity and compatibility.

Method: Use a rag soaked in alcohol to completely soak the area with the self-adhesive label. Wait for a while, then slowly use the rag with alcohol from the edge of the self-adhesive label to the middle. Wipe until all the sticker is removed.

Advantages: Good decontamination effect on glass, stainless steel and other hard objects.

Disadvantages: Alcohol is not easy to obtain and may cause some damage to hand skin.

4. Use Fengyoujing

Principle: principle of similarity and compatibility.

Method: Completely saturate the area with adhesive tape with essential oil, and wipe it off with a dry rag after 15 minutes. If the dirt is difficult to remove, you can extend the soaking time of the wind oil essence, and then rub it vigorously until it is clean.

Advantages: It will not cause damage to almost all items, especially surfaces with prints and paint.

Disadvantages: Decontamination takes a little longer.

Basic principle:

Self-adhesive is a pressure-sensitive adhesive.

Generally composed of base material, tackifying resin, reactive diluent and antioxidant.

Based on the principle of isostructural miscibility of polymer chemistry, the methods for removing self-adhesive are nothing more than dissolution and anti-sticking.

The dissolution method is to use an appropriate solvent to dilute the base material or tackifier of the self-adhesive so that it can be easily separated from the adhered object.

Anti-adhesive rules utilize the properties of self-adhesive components that are repellent to certain chemical agents to prevent re-adhesion of self-adhesive materials
