The trademark on the door can be removed while blowing with a hair dryer.

1. Use a hair dryer to blow hot air against the edge of the trademark for one minute, gently lift the trademark with your fingers, and slowly tear it off. If you feel there is resistance, use a hair dryer to continue blowing against the torn opening of the trademark. The trademark will be completely removed by you.

2. Then, use a warm and wet towel to apply soap on the door, and wipe the traces several times.

3. Finally, wipe off the soap suds with a clean warm and wet towel, and the traces of adhesive will be removed.
