Mildew, that gross, black smudge between the tiles in your bathroom, is a problem that every home faces. Mildew on your bathroom walls is unattractive, and is bad for your health. But don’t worry, with a little bleach and good old elbow grease, that mildew is as good as gone.
Start by scrubbing the mildew area with a tough brush with bristles. This loosens up the mildew from the walls.
Next mix a small amount of bleach with water in a spray bottle, a ratio of 10 parts water to one part bleach is good. Make sure the room is well ventilated, with doors and windows open and even the fan going. Then spray the bleach mixture on the walls and allow it to sit for 10 minutes.
When you are done, rinse the walls with water and the mildew is gone.
