If your backyard patio has a portion located in a shady area, you will begin to see mold-mildew growing on the surface. Outdoor mold removal is just as important as indoor mold cleaning. Besides the fact that mold growth just plain old does not look nice, it can have the same dangerous implications as indoor mold. Outside the mold spores are disturbed more and the wind will blow them and carry them through the air right onto you and your family to breathe in. It can be toxic and it is a leading cause of allergy symptoms. So to keep you family, friends and yourself safe and healthy.
When removing mold-mildew always wear eye protection, gloves, and a mask. Do not attempt mold removal in the presence of children and pets.
Add approximately 1 gallon of very hot water to a large bucket.
Add 2 ounces of laundry detergent, either powdered or liquid laundry detergent work equally as well.
Add 4 ounces of tri-sodium phosphate which is commonly known as TSP. TSP is available in hardware stores or home improvement stores. A non phosphate substitute is also effective which is available in the same type of stores.
Add 16 ounces of chlorine bleach. Any brand will work.
Mix the ingredients, use a wooden paint stir and swirl solution.
Dip a stiff bristle broom in the mold killer and brush liberally over the mold-mildew.
Allow the mixture to stand for approximately 5 minutes on the surface of the patio.
Use the broom to scrub the area. If the mold seems deeply embedded in the patio surface, use a hand held scrub brush to scour the area. Be sure to wear gloves when working with this mold cleaner.
Rinse very well with plain water.
Safely discard the remaining mold killing solution. Do not leave it unattended or sitting for any length of time as this can pose a danger to curious children and pets.
Mold-cleanup is very important to the health and safety of your family, especially children, your friends, your pets and yourself.
There is little that can be done to prevent mold or mildew growth on outside surfaces. There are mold retardant paints and sealers available.
Always clean mold-mildew as soon as possible.
