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.

Parking Lot & Garage Cleaning for Concrete in California
Commercial properties in California need sidewalks, entrances and dumpster areas cleaned regularly, with wash water kept out of storm drains to meet local stormwater rules.
Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.
Some cities in California limit outdoor water use, including washing hard surfaces with a hose, especially during drought declarations. Pressure washers use far less water than an open garden hose, but rules vary, so it's worth checking your city's current restrictions. Wash water should also be kept out of storm drains.
