As far as flooring goes, we typically recommend bleach only for exterior finished wood surfaces, or non-porous surfaces like ceramic tile, vinyl, and linoleum. Remember that bleach should never be used on any marble surface, and Clorox® Disinfecting Bleach should always be diluted when used for cleaning a hard surface or fabric.
Here’s how you can properly dilute bleach for cleaning a painted hardwood floor that is safe for bleach. Be sure the area is well ventilated, and consider working in small, manageable sections to be sure you can rinse quickly and efficiently.
Dilute your bleach
Mix up a solution of ⅓ cup of bleach added to 1 gallon of water.
Wipe away dirt
Wipe or wash the floor to remove visible dirt and stains.Tip
Be sure to test a less-visible section of the wood floor first so you know how the treatment will affect your particular floor. Do not use bleach if any part of the finish is worn or discolored.
Disinfect the floors
Apply the bleach solution to your floor, and allow it to remain wet for 6 minutes.
Rinse and dry
Thoroughly rinse off your hardwood flooring, and allow it to air dry.Tip
Keep kids and pets away until the floor is completely air dry.
