Looking for parking lot & garage cleaning for concrete in District of Columbia? We look at the surface first, choose the right method and pressure for it, and give you a price before any work starts. With concrete, the right approach is pressure wash with a surface cleaner.
Method and pressure
Cleaning solution: A degreaser for oil spots and a pre-treatment for organic growth; post-treatment slows regrowth.
Caring for concrete
Plain broom-finish concrete is the surface pressure washing is made for. A rotary surface cleaner gives an even finish without the stripes a wand leaves, and hot water helps with grease and oil.
Avoid: Holding a narrow tip close to the surface, which etches lines into the cream layer of the concrete.
How often: Every year, or every 6 months in shaded, damp spots.
