Pressure Washing Patio Stones

How to wash patio stones properly

Just like any other surface, pavers, interlocking or patio stones are also always susceptible to dirt. Especially in outdoor areas, it’s very common to see dust accumulation, and when it comes to pavers, it is natural that other types of unwanted “dirt” start to appear. 

Weeds growing at the joints, mold, moss, they are just a few examples of unwanted presences on outdoor pavers.

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.







In most cases, to get pavers clean with a pressure washer it requires using a jet style tip. This amount of pressure will easily damage the surface. Using a fan tip typically will not damage, but likely won’t achieve the level of clean you’re after.

Instead, rely on the experts who know how to pressure wash your pavers with care and efficiency.

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.
