How to Clean Cement Floor With Mold, Mildew, or Moss

More severe stains like mold, moss, or mildew require some extra effort. You must kill the spores or plant material causing the problem; otherwise, it will just return. 

  1. Fill the spray bottle with equal parts hot water and distilled white vinegar. 
  2. Spray directly onto the moss, mildew, or mold area. 
  3. Scrub the area well using the push broom.
  4. Rinse with a bucket of clean water. 
  5. Let the area air dry thoroughly.

For stubborn stains, create a solution combining 1/4 cup oxygenated bleach with 1 gallon of hot water. This will need to sit in place for 15-30 minutes before rinsing and drying the surface.

How Do You Clean Cement With Grease or Oil Stains?

Because cement is porous, oil leaks from cars and lawnmowers can create a deep stain that is difficult to clean. It is possible, though, to clean even these stains. 

  1. Apply a thick layer of baby powder, cornstarch, or clay cat litter, all of which can pull the grease out of cement.
  2. Leave the powder in place for 24 hours. Check in on the stain a few times during this period, and apply more powder if you see grease reaching the top layer. 
  3. After a full day, sweep the concrete.
  4. Combine 1 teaspoon of liquid dish soap with 1 quart of extremely hot water. 
  5. Apply the solution to the stained area and scrub it with a broom or brush. 
  6. Rinse the concrete with hot water, then let it dry.

Tips to Prevent Cement Stains

It’s best to prevent stains than to have to clean them after. These tips can help you avoid getting most stains on your cement surfaces.

Sealants

Applying a sealant to your garage or home concrete floors protects them from stains and keeps the cement looking new. If you want to sell your home, sealing your cement can impress buyers.

Liners & Barriers 

Placing a removable, waterproof barrier between cement and things likely to stain it can be quite effective at protection. In the garage, you can line the flooring beneath your cars with drip mats. Use mats or rugs under patio furniture to catch spills and prevent rusting. Make sure to select a rug specifically designed for outdoor use. Outdoor mats and rugs don’t trap water underneath them that can lead to mildew or mold on your patio. Similarly, use drip trays under any pots on your front steps or patio. Preventing runoff can spare you future stains.

Look out for Moisture

Moisture can discolor cement. Divert rainwater from the foundation using downspout extensions. This will water the lawn rather than your concrete surfaces. Stay on top of falling leaves, too. When leaves collect, they can trap moisture beneath and cause mildew and mold stains.

How Often Should You Clean Concrete?

Cleaning concrete is a year-round task, especially outdoors. You’ll need to sweep cement sidewalks, patios, and steps weekly during the warmer months and once a month during the winter. Similarly, your garage should be swept at least once a month. Clean spills on the concrete immediately when you see them and use fans to dry the indoor cement areas anytime they get wet. Routine cleaning and maintenance of cement and concrete areas is the easiest way to prevent future stains.
