Pressure Washing Patio Stones
How to wash patio stones properly

Although it seems easy, it’s important to remember that for every cleaning method, you must follow a series of guidelines to make sure you’re not damaging your pavers, especially when pressure washing.

Instead, rely on the experts who know how to pressure wash your pavers with care and efficiency.
Instead of using hand held sprayer, consider using rotation cleaners
The surface or rotation cleaner has a spinning head within a contained unit, with rotating arms – similar to a lawnmower. The arms spin as a result of the high pressure of water, which creates a scrubbing action. The greatest advantage in using an industrial surface cleaner is that they eliminate the “zebra” striping, which is typical to cleaning done with regular wands.
When more power is needed, use a turbo rotary nozzle but with care.
This special attachment or so called nozzle tip increases the psi substantially. It spins a zero degree spray, in a 4-8 inch circle, at over 3000 rotations per minute. The spinning water jet hits the surface from multiple angles, which quickly breaks down crust on dirt and grime.
