Cleaning and a solution to mildew on antique bricks

Mildew builds up quickly in the shade. Power washing wastes water and can peel paint coatings or old patina from antique bricks.

Good ways to keep pool decks clean is as follows:

• Wet the entire surface with a garden hose
• Mix up a solution of 50% pool chlorine and 50% water in a plant watering can
• Spread or spray the solution on the wet deck and let it soak for 5 to 10 minutes
• Rinse the deck and as it dries the surface should bleach clean. Use household cleaners like "Simple Green" or "409" and scrub difficult spots. You can tell chlorine is gone when bubbles (similar to a soapy solution) are no longer present.

For patios, pathways, steps and driveways, try the same technique except use a mix of water, dawn detergent and Clorox. (Always start with water before adding Clorox so as to avoid mixing concentrated chemicals.) This mix spreads easily with a dampened broom.

 

The recommended average frequency to perform this treatment is once every 2 months (depending upon dampness and rainfall). It is important to remember that decks/patios etc. facing north are more susceptible to mold and mildew (because they have less exposure to the sun); therefore will require more cleaning.

Chlorine and Clorox are slippery by nature. Keep safety a priority. Wear eye protection and take care to rinse down the surface thoroughly. Remember the bleach will rot cotton threads or materials.
