Method 1
Soak the towel in warm water (hot water in winter) to make it moist, and wipe it repeatedly at the trace of self-adhesive paste twice (more times according to the situation), or wipe it with a towel in a pot with less warm water.
Then, put soap on the bottom of the pot with a warm wet towel and wipe it several times at the trace.
Finally, wipe the soap foam with a clean warm and wet towel, and the adhesion marks will be removed.
Method 2
Blow hot air on the edge of the trademark with a hair dryer for one minute, gently lift the trademark with your fingers and slowly tear it open. If you feel resistance, continue to blow on the torn mouth with a hair dryer, and the trademark will be completely removed in a moment.
