Around here we use the term pressure washing. I know in many parts of the country power washing is the term used more.
Who said that? Dictionary?The term Power Washing is moving the wand knee high from the surface, cleaning a wider area with one stroke of the wand. Similar to a glorified rinse job.
Pressure Washing is cleaning inch by inch. It is a much deeper cleaning and takes talent to clean in this manor without damaging the cement...... etching.
