1, use a toothbrush
If only a small part of the wall is moldy, you can use a toothbrush to remove the mold from the wall. If we want to prevent the mold from spreading further, we will clean it with a toothbrush and then wipe it on the wall with alcohol, which will dry the wall and prevent the mold from regenerating.
Step 2 clean with bleach
If the walls are moldy, they can also be cleaned with bleach. You can dilute the bleach with water and put it in a spray bottle, and then spray it on the mold on the wall, which will also clean the mold on the wall. If you don't want bleach to get on your hands, you'd better wipe the wall with cotton cloth.
Use alcohol
If the indoor walls are not very moldy, we can also clean the walls with alcohol. After diluting with alcohol and water, brush it on the moldy wall to remove the mold on the wall. However, it should be noted that when using alcohol to remove mold, you must avoid alcohol from touching yourself, and at the same time, it is best to ventilate after brushing alcohol on the wall.
