If you notice unsightly dark spots on your shower grout, it’s time to start cleaning.
The mold in your grout can be eliminated using three things: bleach, baking soda, and plastic wrap.
To remove grout mold, begin by creating a paste with 1/4 cup of bleach and 3/4 cup of baking soda. Using a toothbrush or a paintbrush, apply the paste to the moldy grout areas. You can use this brush for applying the paste and for thorough grout scrubbing if necessary.
Once applied, use the cling wrap to seal the solution in place and prevent it from drying out.
Let these areas sit for about an hour. Afterward, lift a corner of the plastic wrap and check if the mold comes off when you wipe away some of the paste. If it does, you’re finished! You can proceed to wipe off the remaining areas and rinse with water.
If the mold is stubborn, wait for another hour and try again.
