Ocean Spray utilizes high pressure ground surface cleaning machines to remove embedded dirt, grime, mold, and algae from horizontal surfaces without the need for an excess of toxic chemicals that harm the surrounding plants and animals. Over time, contaminants settle into the porous surfaces of concrete, asphalt, tile, stone, brick, and wood, making them very difficult to clean with household chemicals and equipment. Our machines require minimal water and can operate at up to 3500 psi to agitate and wash away years of accumulated dirt and grime, leaving the decks and walkways around your home looking bright and renewed.
