Over the past 18 years we have developed this incredible environmentally safe cleaning product that will not harm our planet or your pocket. This new technology allows us to clean exterior stains caused by Mold, Mildew, Fungus and Algae without damaging roofs, sidewalks, stone sculptures, siding, wood, awnings or plants! The new Green Cleaning system has allowed us to save Homeowners, Property Managers, Associations, and many others thousands and thousands of dollars in repairs. Our technology does away with the old technique of pressure washing and scrubbing. Citra-Shield™ is the new gentle cleaning system to keep all of your exterior surfaces looking brand new.
