3 tips for cleaning mould on basement concrete

Basements tend to be dark spaces with poor ventilation and higher humidity levels than other parts of the house. These conditions can lead to mould developing quickly. Mold can cause health problems for the inhabitants; that’s why it’s important to identify and prevent mould.

Cleaning mould on basement concrete can be a losing battle unless you address the root causes. Foundation leaks, caused by cracks in walls and floors, and condensation on plumbing and vents tend to keep basement humidity levels higher than other parts of the house.

Another reason why it’s difficult to clean mould on basement walls is concrete’s porous surface. But don’t give up! There are effective tips for combatting the problem. Here are 3 tips for cleaning mould on basement concrete.

Use liquid laundry detergent

While bleach is effective for killing mould on non-porous surfaces (for example, in the bathroom), laundry detergent is often a better option for concrete, since it penetrates the pores. Make a cleaning solution by mixing a cup of laundry detergent with a gallon of water. Use a sponge or brush to apply the solution to the concrete in your basement. The detergent will enter the pores, killing the mould down to the roots. When you’re finished, rinse off the concrete with clean water.

Make a white vinegar solution

If you’re looking for a natural cleaner to decontaminate mould, use white vinegar. The acid in the vinegar will kill the mould. Make a white vinegar solution consisting of three parts water and one part vinegar. Apply the solution with a sponge, then scrub vigorously using a brush. You want the solution to penetrate the concrete’s pores, so it can attack the roots of mould. For especially difficult mould stains, let the solution penetrate the concrete before you scrub.

How to prevent mould from developing on concrete

Moisture and mould are common problems in houses. The best way to solve your concrete mould problem is to prevent it from occurring in the first place. To do this, you need to eliminate the essential condition that mould needs to grow: moisture. Repair leaking pipes and cracks in concrete. A dehumidifier is also a great way to control basement moisture and prevent mould growth. Remove wet materials such as cardboard, wood, furniture made with fabric and carpets.
