1. Observe the Room

Next, let’s discuss about the steps to remove the mold. First, safety glasses, mask, rubber gloves and long sleeved jacket must be put on. Why? Because the fumes produced by bleach can be dangerous for health if touched or inhaled; it may cause dizziness and also respiratory problems (for asthmatics, get help immediately if it is inhaled).

After that, put liquid soap in the bucket, mix it with warm water. Use sponge to wipe dirt or debris on the wall, keep doing it until the wall is cleaned. Then, take out the soap water in the bucket and replace it with another warm water and mix one cup of bleach in it, do not forget to clean the sponge too. Soak the sponge or scrub brush in bleach water and use it to scrub the wall.

Let it sit for a while. After that, clean the wall with mixed water and detergent. Detergent is known to have a good effect in erasing fumes creating by bleach. Then, rinse the wall with water and then dry it using the dry cloth. For preventing the mold to grow, it is better to repaint the wall with anti-mold paint.




A basement is a humid place to begin with, so mold will keep growing eventually if there is no intensive precaution or cleaning routines. If there is any other way to prevent the mold from growing, it is to put some installments like windows or more ventilation so the sunlight can warm the room, killing the bacteria and decreasing humidity at the same time.
