Sanitize A Basement

What Is The Best Way To Sanitize A Basement?

A well-sanitized basement is essential to the overall health of a household. Being the lowest portion of the house and exposed to water or moisture, especially when the basement waterproofing has been compromised, the basement is most likely to be home to mildew, mold, and other microorganisms that can affect the human health.

The primary reason why the basement may require sanitation is the presence of water via leaks through the walls, slabs, foundation, or from the ground, or flooding caused by rainwater or drain backup.  As a result, the best way to keep water away is basement waterproofing. With or without water leakage into the basement, here are some of the best ways to sanitize a basement.

  1. Apply Bleach to Sanitize Smelly Basement

Due to its proximity of water, mold and mildew can begin to grow in the basement and cause malodorous, musty odor. To get rid of the bad odor, open the window for fresh air and put on a dehumidifier to remove moisture. Now you need to eliminate the source of the smell. Get a spray bottle and pour a mixture of about 2 ounces of household bleach and water in the bottle. Spray the mixture on the floors and walls of the basement, and scrub with a stiff nylon brush.

  1. Scrub with Detergent and Ammonia Solution

One of the ways to sanitize a basement, especially the concrete surface that is dirty is by getting a bucket of warm water and add a mixture of detergent and a quarter cup of ammonia. Pour the solution on the concrete surface with a brush. Use a stiff nylon and avoid an iron brush because the iron fibers can fall off on the concrete and later, rust and that can create another problem. Rinse and leave the basement to dry.

  1. Clean the Efflorescence with a Stiff Nylon Brush

Efflorescence is the white powder, the soluble salts, that remains after water has seeped via concrete and evaporated. When the powder accumulates on the floor or wall of the basement, use a stiff nylon brush or mop to clean it. Afterward, you can consider rerunning a basement waterproofing process.

  1. Sprinkle Bleaching Powder on the Floor

If your basement is smelly, you can sprinkle it with bleaching powder, also known as chlorinated lime (check the laundry section of any supermarket). Let the powder sit on the bad odor and the microorganisms that caused it, for about 24 hours before sweeping or vacuuming it up.
