first of all, you need to tear off the trademark stuck on the bottom surface of the pot, which can be directly torn off by hand.

soak the towel in warm water (hot water is used in winter) to make it wet, and then wipe it on the trace of self-adhesive twice (more times as appropriate), or use it in a pot with less warm water, and then wipe it with a towel.

Soap the bottom of the pot with a warm and wet towel, and wipe the trace several times.

wipe the soap foam with a clean warm and wet towel, and the adhesive traces will be removed.
