Method 1: Moisten the dyed part with water (suitable for small-scale pollution), then cover the dyed part with edible salt, then rub it repeatedly with your hands for more than 5 minutes, and then rinse it with clear water.

Method 2: 84 disinfectant with strong decontamination ability can be used, but it needs to be diluted in a certain proportion. At present, the conventional dilution ratio is 1 30, and then the clothes are soaked in it. The specific soaking time needs to be grasped according to the position and degree of the dyed clothes, otherwise the required effect will not be achieved in the end (note that it is best to wear rubber gloves all the time to prevent 84 disinfectant from hurting the skin).

Method 3: You can drop household vinegar on the surface of the dyed clothes, then wait for 10 minutes until the vinegar reacts with the color, and then wash it with alkaline soap.
