How to Clean Mold from Bathtub and Shower Tile Grout

You need to know how to clean mold off tile grout to maintain the health and integrity qualities of your bathroom. Not only are black mold stains in your shower grout unpleasant to look at, but if they are left long enough, the mildew and bacteria can be bad for your health as well. Whether you are using eco-friendly cleaners or abrasive scouring powders, you will need to put some effort into getting your grout looking new again.

Step 1 - Choose Cleaning Products

With so many products on the market, finding the right cleaner for the job can be a difficult choice. Before you head off to the store, think about what kind of cleaner you would like to use: does it have to be eco-friendly or are you willing to use strong chemical detergents?

If your mold problem is particularly bad, you might want to ask for a product used by professionals. Trust the experts at your local hardware store; they’ll be happy to point you in the right direction.

Step 2 - Surface Cleaning

Mold and mildew can hide under soap scum, so you will need to do a general surface clean before attacking the black stains on your bath and shower grout. Sprinkle the entire tile surface area with baking soda and wipe clean with a cloth dampened with vinegar.

Pay special attention to the grouted areas. Rinse with warm water and let the tiles dry. Repeat this process until there is no white residue on the tiles after they have dried.

Step 3 - Grout Scrubbing

In a small bowl, make a paste of scouring powder and warm water. Wearing latex gloves to protect your hands, apply the paste to the moldy grout with a soft scouring pad. Scrub black mildew stains vigorously without gouging the grout from between the tiles.

If mold stains remain in your tile grout, use a toothbrush to carry out deeper cleaning. Rinse with warm water and let the tiles dry. You may need to repeat this process a few times before mold stains are completely gone.

Step 4 - Anti-Mildew Spray

Use an anti-mildew spray to kill the mold-causing bacteria. Make sure the spray coats the affected area evenly, leaving the tile and grout wet but not soaked. Leave the anti-mildew spray to dry overnight. Re-apply anti-mildew spray, scrubbing the tile and grout with a soft scouring pad on the second application. Rinse with warm water.

Step 5 - Mold Prevention

Although you cannot entirely prevent mold and mildew from returning, there are a few things you can do to keep it under control. Use a squeegee to clean away excess water after every bath or shower.

Also, use an eco-friendly after-shower tile spray at least every second day. When scouring your bathroom, don’t just surface clean tiles, but take the time to scrub the grout in between as well.
