A thick double-sided tape is stuck on it, and the people below can reply, but hot water blows the fastest, but the effect should be the worst, because the glue will melt and the glue layer is still on the door. General domestic workers will use special cleaning agents to do this. The effect is very good. Of course, if you do it yourself, use things from home. For example, Mr. Wittmann, if you want to wash oil and similar things, first use a brush and then use woolen cloth, so that it can be done at one time without hurting the door, and the effect is particularly good.
