What are the tricks to deal with moldy walls?

You can clean up the mildew spots with a (dry) toothbrush first, and then gently wipe them with a soft cloth dipped in alcohol, so as to keep the wall dry and prevent the recurrence of mold.

2. Pour bleach (powder) and water into the spray bottle according to the ratio of 1:99 and spray it on the moldy wall. Wipe the wall with a rag, then rinse with clear water, and brush the mildew-proof paint after drying, which can protect against moisture for a long time.

If the mold is not too serious, you can wash the wall with 80% alcohol. Pay attention to ventilation and wear protective gloves, masks and glasses when cleaning.
