Frequent rainstorms and hot, humid weather can contribute to the growth of mold on your driveway. Mold thrives in warm, moist areas and can cause a myriad of health and respiratory effects in those with allergies or compromised immune systems. Mold spores from the driveway can be tracked on your shoes and proliferate inside your home. If you can't remove the source of the mold--such as rain or humidity--you can still keep the driveway as clean as possible to help prevent future mold growth.
Fill a bucket with 1 gallon of warm water and 1/4 cup of laundry detergent. Put on rubber gloves and a cotton face mask.
Pour the bucket of detergent and water onto the driveway to soak it. Make more solution if needed to cover all of the moldy areas.
Scrub the driveway using a stiff-bristled broom or scrub brush.
Rinse the driveway with a garden hose and allow it to dry.
Fill a bucket with 1/4 to 1 cup of bleach and 1 gallon of warm water. Pour the solution onto the driveway and allow it to sit for 20 minutes.
Make another bleach solution and pour it onto the driveway. Wait 20 more minutes for the bleach to kill the mold.
Rinse the driveway thoroughly with a garden hose.
Prevent future mold with a borate solution. Mix 1/4 cup of borate detergent with 1 gallon of warm water in a bucket.
Pour the solution onto the driveway and allow it to dry. Don't rinse it. This can help prevent the growth of mold.
