Mold and mildew can be removed from exterior doors with a solution of 1/3 cup of powdered laundry soap, 2/3 cup of trisodium phosphate, 1 quart of bleach and 3 quarts of water. It is important for individuals to wear gloves and protective eye wear when applying the solution, which should be applied to the affected area with a soft-bristled brush.
After the mold and mildew have been successfully removed, the next step is to rinse the affected areas with clear water. Mold or mildew that has developed on wooden exterior doors can be removed with a solution of 5 tablespoons of washing soda and 1 gallon of water. The first step is to remove any excess mold or mildew with a soft cloth that has been dipped in the solution. The next step is to rinse the affected area with cool water. Once the area has dried and all traces of mold or mildew are gone, the final step is to polish or wax the wood.
Mold and mildew are caused by excess moisture. If signs of re-growth occur within a short period, it is important for homeowners to schedule an inspection with a mold specialist to ensure efficient removal and prevent additional damage.
