Mopping Floors with Bleach

By Dr. Laundry July 18, 2011

Q: Bleach sometimes affects my asthma when I clean with it; how much liquid bleach do you recommend when mopping floors?

A: You probably know this, but it’s always good to clarify:  Clorox® Regular-Bleach should always be diluted when used—we never recommend using it full strength for cleaning any hard surface or fabric! 

For mopping floors (ceramic tile, vinyl, linoleum—not marble or other porous surfaces that aren’t safe for bleach), mix up a solution of ¾ cup bleach added to 1 gallon of water.  For disinfecting, wipe or wash the floor, then apply the bleach solution and let stand for 5 minutes.  Rinse well and air dry.  Also, be sure the area is well ventilated while you are working.
