When cleanliness becomes a topic of conversation, one thing should come to mind, Pressure Washing. Since there are so many factors involved in pressure washing, it is wise to have the knowledge of what to use and when to use it. Proper pressure washing techniques would entail knowing the in’s and out’s of the equipment being used, the selection of a hot or cold water system, the correct spray distance from the surface, tip selection for accurate degree of spray and what, if any, chemicals to be used. At ACV, we generally use a 3500 psi, cold water system and avoid using any chemicals unless necessary, depending on the job. If you have any unsightly mold, algae, dirt or grime on any various types of surface, it is time to call ACV.
