First, because underwear is left in a humid environment for a long time, some human dander remains on underwear, which will form protein and salt, which are nutrients of bacteria. Clothes are not cleaned in time or washed without cleaning, and bacteria in the air cover the clothes, which will lead to mildew and form black mildew spots after air drying.

Second, the cleaning method of black mold on clothes

1, bleach

Bleach heats diluted water, and clothes are soaked in it for one hour before daily cleaning, so black mildew spots can be easily removed. (Note: Use special bleaching powder for colored clothes, otherwise it will fade easily. )

2. Taomi water

It takes a long time to soak clothes with moldy spots in rice washing water, because protein in rice washing water can adsorb some molds, so it can remove milder moldy spots.

3, alcohol cleaning

Where clothes have black mildew spots, you can apply some 5% alcohol solution, or scrub them repeatedly with hot soapy water for several times, and then scrub them as usual, and the mildew spots can be completely removed.

4, mold special cleaning agent

The method of washing clothes with special cleaning agent for mildew spots is simple and efficient. However, when washing clothes with a special cleaning agent for mildew spots, attention should be paid to separating clothes without mildew spots.
