1, with essential oil. You can remove the trademark glue with essential oil. Dip a cotton swab in essential balm and apply it to the surface of the trademark, completely wetting the area of the trademark. Better use it more. After waiting 15-20 minutes, wipe with paper towel or cloth, or rinse under the tap. Remove the colloid attached to the cup wall with a light button or eraser.

2. Use hand cream. You can use hand cream to remove the trademark glue. Glycerol and surfactant can penetrate between the trademark glue and the cup wall in common hand cream, which can dissolve and then clarify some colloids. Similar skin care products and facial cleanser have the same effect. After soaking completely, just wait 15-20 minutes.

Step 3 use gasoline. Gasoline can be used to remove trademark glue. Dip the cloth in a little gasoline and gently rub the trademark glue, and it will soon fall off. Before using gasoline, you should pay attention to stay away from the fire source. Gasoline also has a "corrosive" effect on some plastics or paints, so you need to use it more carefully. You can wipe it in other places first, and then use it after it is no problem, and you should use it in a small amount for a short time.
