Scrub the grout with a brush to remove any stubborn mold stains. Remember to wear protective gear, such as gloves and goggles, and ensure proper ventilation when working with bleach.

It is important to note that bleach should not be used on unsealed grout, as it can degrade the material and be less effective in mold removal. Additionally, never mix bleach with vinegar or hydrogen peroxide, as this can create toxic fumes.
