What should I do if the bathtub is dyed with a towel?

If the color has penetrated, there is no way out. Rough handling can cause damage to the bathtub surface.

You can try it if you don't infiltrate it.

1. First scrub with detergent containing surfactant components such as detergent, and then wash with clean water;

2. Then dilute it with bleaching powder solution or bleaching powder solution with 84 water, wet it with a small cloth and scrub it carefully, and then wash it with clear water.
