Epoxy grout can be cleaned with a spray bottle mixture of 50% bleach and 50% warm water. Spray the grout, saturating the area to be cleaned, and let it sit for 10 to 15 minutes. Rinse and repeat if needed. When using bleach always wear gloves and have an open window for air circulation.
If bleach is too strong a chemical for you there are plenty of other ‘on hand’ materials you can use. Make a thick paste with baking soda, water, and vinegar. Apply and lightly scrub with a toothbrush. Baking soda acts as a whitener and will keep your grout cleaner
, longer. This will kill bacteria and mildew as well as remove body oils and soap scum. Vinegar is also a great odor remover.
but be carefull as Vinegar can burn cement grout and can damage some tile glazes if left on for too long: make sure you rinse it well. Always test a small area before doing an entire project to check for damage. Be sure to re-seal grout after heavy cleaning. This will keep it resistant to stains, mold, and mildew for a longer period of time.
