If your raincoat is a raincoat, when the raincoat is wet, you cannot bounce the rainwater on the raincoat with your hands or a fur hat, because doing so may damage the waterproof performance of the fibers in the raincoat. Rainproof raincoats are not suitable for frequent cleaning. If you wash it frequently, it is very likely that the waterproof performance of the raincoat will be reduced. If you think your raincoat is too dirty, you can rub the raincoat lightly with some water, then dry the washed raincoat, and hang it to dry.
