Your floor is one of the many places mold can grow, and though it's possible to clean, the type of floor you have will dictate what kind of cleaning method you should use. The primary reason for this is some surfaces are porous and others are not, while some can be cleaned with large amounts of liquids and others should be kept as dry as possible.

Cleaning Carpet

Carpets are some of the most porous surfaces, and also the hardest to clean because of how mold can hide within the carpet threads. Because of this, cleaning will require heavy attention on any area where mold is growing to make sure you are being thorough.

Start by applying a layer of baking soda to the area. If the mold growth was caused by a heavy amount of moisture, the baking soda helps suck up some of that moisture. Leave the baking soda on overnight, then vacuum it up the next morning.

Next, spray a small amount of a mold-cleaning chemical onto the area. You can use white vinegar or an anti-mold or anti-fungal spray, or even a carpet cleaning product. Then, using a scrub brush, scrub the area vigorously. You'll want to make sure that the solution is deep inside your carpet.

Finally, use a steam cleaner to clean and dry your carpets entirely. This is primarily to help wash out the chemicals you just used; while you may be tempted to use a steam cleaner instead of scrubbing, steam cleaners often don't have the power to get deep inside the carpet threads and could miss many mold spores.

Cleaning Wood Floors

Wood can be challenging to wash, because you don't want to get it very wet or leave it wet for very long or it could start to warp. Luckily, many wood floors have a water-resistant finish that also prevents mold from getting deep into the wood. If the finish on your wood floors is intact, the mold will only be able to grow on the surface, so you should be able to wipe it up with a minimal amount of cleaning chemical like bleach. You can also use a scraper to pull the mold away from the wood.

If the mold has penetrated the wood, however, you'll need to be a little more thorough. Use a mix of detergent and water in small areas, then use a scrub brush to gently remove the mold from the area. Avoid soaking large areas; work on areas that you can dampen, scrub, then dry in quick succession.

If the mold is deep in the wood, there's a silver lining; though intense scrubbing and use of chemicals like detergents and bleach will discolor the wood, you will need to refinish the wood anyway, so you can be as thorough as you need without worrying about ruining the color of your wood.

Cleaning Tile

Tile itself is rarely very porous, and like with wood, you can remove mold growth by wiping or scraping the mold away. The problem comes from the grout, which is very porous – and unlike carpet, which is flexible, it cannot be moved, so you will have a harder time getting into the crevices.

The cleaning process for grout can be tedious. Pour or spray a solution of bleach and water into the grout, then use a scrub brush or a toothbrush to work the solution in between the holes in the grout and scrub away mold and spores. Since grout is sturdy, you can apply a decent amount of pressure here while cleaning.

When you're finished, rinse it with water and set it up to dry. You can apply a sealer to the grout to prevent future mold growth once it's dry, and discourage any remaining mold spores from growing.
