How to deal with the moldy white wall?

1. If the moldy area is small and the moldy spots are small, not one by one, then it is suggested to brush off the moldy spots on the wall with a small brush. Pay more attention to the ventilation of the house after painting, otherwise the white wall will still be moldy. 2, you can use a hair dryer to blow, it is best to use hot air to blow. Blow-drying moldy places on the wall can dilute or eliminate moldy traces. 3. If the moldy area of the white wall is too large, it is recommended to repaint it all. It's best to ventilate for a while before painting, and then paint again when the moldy part is dry.

/The reasons for this situation are:

1, probably because the location of the house is not so sunny, and it is not ventilated often. In particular, some houses that have been renovated but no one lives all the year round are often airtight, and it is easy to have moldy walls.

2. It is also possible that the wall insulation of the house is not done well, which will lead to catching cold.

3. It may also be because the indoor pipes are aging or damaged. Because the pipeline surrounds the whole house, once the pipeline ages, it will drip or leak. Then the whole house will be wet and the walls will be moldy easily.
