7) Vinegar and hydrogen peroxide
A solution based on vinegar and hydrogen peroxide is really very effective against more persistent mold, and especially against mold that settles between tiles or in the shower. Dilute the vinegar and hydrogen peroxide in a medium-sized bowl. After mixing, pour the contents into a spray bottle and spray it directly on the affected area. Scrub with an old toothbrush or cloth and finally let it air out.
