    Eliminating Green Mold From Concrete Steps

    Q: The concrete steps at my house are moldy and kind of green on the risers, except where I applied a concrete sealer. I did it badly, so you can see areas that look like drips. How can I safely clean the concrete?

    Hyattsville, Md.

    A: When you ask for a way to safely clean concrete, you dont say whether your goal is to protect the concrete, yourself or your plants. Luckily, its possible to do all three.

    The least expensive option is to use a little chlorine bleach diluted in water. Bleach solution doesnt damage concrete, but it isnt something you want in your eyes or on your skin or clothing. You could wind up with spots of white or odd colors because bleach affects fabric dye colors unevenly. So before you start working on your steps, put on old clothes, long rubber gloves and goggles, and have a bucket, a sponge and a synthetic scrub brush handy.


    When everythings ready, sweep or vacuum the steps to remove loose dirt and debris. Then mix three-fourths to a cup of bleach with one gallon of water, and sponge it onto all the areas where you see the green stains. Keep sponging on more as needed so the concrete stays wet for five to 10 minutes. Scrub with a synthetic brush, then rinse thoroughly. Repeat the process if the concrete is still stained. Rinsing with a hose will dilute whatever cleaning solution is still on the concrete, so it wont harm plants where the water drains.

    Cleaning Starts With Prevention

    How to Remove Mold and Mildew from a Patio (without using a pressure washer)!

    The best way to keep your concrete clean starts with prevention, which means sealing the concrete and keeping the surface clean. Sealing new or freshly cleaned concrete slabs, walkways and pavers help prevent stains from forming, according to Peacock Pavers. Plan on annually cleaning the concrete and reapplying the sealer to the concrete every five years. When cleaning, start by thoroughly wetting the area before using a mild, nonacid cleaning solution to wash your concrete patio and walkways.

    Regular maintenance routines will greatly reduce the need for using chemicals to clean stains. Sweep off leaves to prevent tannin stains and wipe up spills quickly, especially liquids like wine or coffee. Use a non-wire, stiff-bristled brush or broom when sweeping away leaves and dirt or scrubbing out weeds and mold because wire bristles will scratch the sealant and concrete surface. Prevent rust stains by regularly checking wrought-iron patio furniture to be sure the metal is sealed.
