How Do I Clean Fungus and Mold From a Cement Grave Marker?

Without treatment, concrete grave markers can deteriorate.

If left untreated, concrete grave markers are susceptible to infestation by fungus and mold. This can eventually damage the grave marker and make it look less attractive. To remove fungus and mold from a cement grave marker, you will need a chemical biocide, which you can purchase at most garden stores. The application of a concrete protector, also available at most garden stores, will prevent future infestations.

Instructions

1. Put on your protective clothing, including gloves, goggles and mask.

2. Liberally spray a chemical biocide, such as Qualgex Surface Biocide, over the entirety of the grave marker. Rub with wire brush until fungus and mold are removed. Rinse the grave marker with water.

3. Spray a mixture of equal parts ammonia, vinegar and water liberally over the entirety of the grave marker surface and rub in with a soft cloth. Rinse the grave marker with water.
