Helping another customer here in Edmond, OK with a concrete back patio professional pressure wash cleaning. The customer wanted all the black mold growth to be removed. We prepped the area by removing any and all patio furniture, grills, plants, etc. After removing items and surface level dirt, we began treating the concrete with a commercial soap (Tomahawk Degreaser from Extreme Wash Gear) to attack the black mold. After a few minutes, we pressure washed it off with our 28 inch surface cleaner to remove all mold and dirt embedded within the concrete. The end result was a success! The customer could not have been more happy and wants the Urban Cleaning Pros team to come back out and pressure wash their driveway as well!!
