Use vinegar

Leave this mixture overnight if possible, or for several hours depending on how much time you have.

Remove humidity

You can remove humidity using a dehumidifier or fan that is placed in your bathroom.

This will help reduce the Grout Mite population by drying them out, just be sure to empty it often so mold doesn’t have time to grow inside of the reservoir!
