Caption 1What is powerwashing?

A high-pressure stream of water is passed through a wand that is moved slowly and carefully, back and forth along the grain, over exposed wooden surfaces to be cleaned.

The powerwasher pump converts garden hose pressure of 40 psi (pounds per square inch) to as high as 3000 psi. Pressure is adjusted during cleaning as appropriate to the wood’s type, age and condition.
