Hi, I would like to know if its legal to use pressure washer to clean car on a public road ?
Answer
Pressure washing contractors do it every day, the legal issue has to do with reclaiming the water. Some cities are mandating that if you wash a car with a pressure washer, you must have a system to vacuum the water back up. They state that cars get many contaminants that should not be washed down the drain. Some cities will require you to pick the water up, AND have a special permit to do so. Check my sources- I have included a forum discussion on this among pressure washer contractors, and a document from the New Hampshire Department of Environmental Services. Check with your county, city, and state for the mandates to make sure you are not breaking any laws.

What good is a surface cleaner for a pressure washer?

So I am new to pressure washing and I had some questions! I have seen a thing called a surface cleaner and it looks like it does the same work a pressure washer does but just easier and faster! Will you explain the difference between normal pressure washing and a surface cleaner?
Answer
When you say "surface cleaner", I assume you're referring to a device that hooks up to a garden hose, not a chemical treatment.
A surface cleaner can only deliver water at your water line's pressure. This should be between 40 and 80 psi (pounds per square inch).
A pressure washer has an internal, electrically operated motor and pump which delivers water at around 10 atmospheres (1500 psi).
A pressure washer will clean grime off that a "surface cleaner" won't. If all you have to clean is superficial dirt and debris, a surface cleaner should work just fine.
If however, you have embedded dirt debris, or moss, a pressure washer is what you need.
NOTE: Be careful what you use a pressure washer on. It can damage some surfaces and remove paint.
