No matter what type of shower you have, at some point you’re likely to experience mold, mildew, and even hard water deposits. Mildew and mold can grow on your granite shower tiles due to moisture and too little ventilation, but it’s important to treat the problem the right way to prevent damage to your natural stone and keep the mold and mildew from returning.
How to Remove Mold & Mildew from Granite
The safest and most effective way to kill mildew and stubborn mold on your granite shower tiles is a simple solution of one part laundry bleach and one part water. You can spray the solution onto the affected areas and use a non-scratch nylon pad or bristle brush to gently scrub away the mildew and mold without scratching or damaging the granite. Allow the bleach solution to sit on the granite for about 15 minutes before rinsing away with warm water. This process will not damage the tile, but make sure you ventilate the area due to the bleach fumes.
Clean the Granite Tiles Once a Week
To keep mold and mildew from returning, make sure you clean your granite shower tiles about once a week. You can use a stone-safe cleaner such as Granite Gold Shower Cleaner® that also works to remove soap scum and water deposits from the surface of the granite.
Squeegee After Every Shower
Mold and mildew need a damp place to grow, and your granite doesn’t appreciate standing water. You can help eliminate their breeding ground by simply using a squeegee on the walls after every shower. This will remove excess water and allow the granite to air dry quickly.
Scrub the Grout
The grout between your granite tiles also needs to be cleaned periodically to prevent mildew and mold. You can use a nylon bristle brush and a granite-safe, non-abrasive cleaner like Granite Gold Grout Cleaner® to gently scrub the grout lines. After scrubbing, rinse with water and dry the grout with a dry towel.
Seal the Granite Regularly
A protective sealer keeps water and bacteria from penetrating into the granite. If your granite’s seal is allowed to wear away, it will allow staining, water penetration, and worsening mold problems. Stone cannot be over-sealed, so make sure to apply sealant frequently to protect your granite shower tiles and keep them looking new. A good seal will also make the granite easier to keep clean.
Polish the Tiles
Polishing shower walls and tub surrounds helps prevent soap scum buildup. Do not use on floors because they can become slippery.
Ensuring your bathroom and shower have adequate ventilation is key to stopping mold and mildew from getting a foothold. If your bathroom does not have an exhaust fan to remove moisture from the air, you can add a small dehumidifier or open a bathroom window a few inches during showers. Leave your shower door open after every shower to increase ventilation and allow the stone tiles to dry faster.
