Disinfecting Concrete Floor

ralphgumbyApril 1, 2007


Just had the hot water tank let go. Thankfully, not too much water, but I would like to ensure that no mold can start growing. The basement is unfinished. I am keeping the basement door open to ventilate the area. Any suggestions as to what to use? I've read diluted bleach (1 cup/ gallon water), Hydrogen Peroxide (sprayed) followed by white vinegar (sprayed), I'm sure there are other ideas.

All suggestions welcome.

Thank you,

I think those are unnecessary. Certain combinations might produce poisonous gases. Staining of the concrete is a possibility. Just dry the area. Concrete itself will not support fungus growth. Fungus grows only on organic material, concrete is mineral.

Bleach will work just fine but the real key to is make sure the excess moisture is gone. Buy/rent dehumidifier.

Nothing much grows on plain concrete.
If there is a lot of dirt and crud, wash it, vacuum up any excess water with a wet vac, and let the room dry out.
