Grime, mildew and stains build up a little at a time until one day the outside of your property looks years older. Patio Cleaning for Concrete in Derry Village, NH brings it back, usually in a single visit. With concrete, the right approach is pressure wash with a surface cleaner.
The right method for the job
Cleaning solution: A degreaser for oil spots and a pre-treatment for organic growth; post-treatment slows regrowth.
What to know about cleaning 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.
