Pressure cleaning your south florida homes surfaces should be done every 6 months to maintain its clean look and feel. 6 months is about the time it takes for new mold growth to take the old ones place. Especially when added tree and high humidity is looming around, keeping moisture in the roof tiles and damp driveway surfaces. High humidity is what keeps bacteria growing and thriving. The best solution is to clean off with pressure and add chlorine to kill the bacteria.
Some boca raton homes can go approximately a year without a good cleaning because of the area or because the previous cleaning got rid of all the algae and mildew that was growing on the roof and homes surfaces. When tackling any pressure cleaning job we recommend you find a professional service provider in your local area. If you choose to go on doing the job yourself it is best to look for a gas powered pressure washer that is 4 gallons per minute and about 2500 psi. This type of machine will allow a deep clean and be able to use a surface cleaner with about 16 inches in diameter. This type of machine also allows for the chemical application to take place for bigger areas like driveway and large back pool patios. Be sure to use industrial soaps for a proper clean and a proper cling.
As a homeowner it is best to do this sort of outdoor work early in the morning as the suncomes up when it is fresh out or later in the day when the sun has gone down. With a hot south florida heat day this will tire you out and can be very dangerous. For a gas powered machine use a downstream injector to spray the soap and chemical via a small tube that is dipped in the cleaning solution with the injector acting as the adapter. Please note whenever taking on any cleaning job especially with high pressure and chemicals it is best to proceed with caution.
