Washing with a pressure washer Dumb question

I ordered a pressure washer and a foam cannon attachment, but I am confused about how to do the washing process with them.

Do you rinse the car before you foam it? Is it bad to pressure wash a dirty car- will it make the dirt scratch the finish?

 

i would suggest rinsing the car at pressure first to remove as much surface contamination as possible, then foaming it, letting it dwell, then rinse again at pressure. then wash using 2BM.

 

Excellent answer. Exactly how I do it.:thumb:

 

spank you very much. i mean...thank you very much. :giggle:

 

I rinse before I use the cannon.

 

:ditto:

 

:thumb:Thanks!

 

Yep, that's about right!

 

i do the samething but could i rinse, foam car and let it dwell than instead of rinsing again i just wash it with a wool sponge?

 

It's safer to rinse again because it pulls more contamination off.

 

This is the way to go...:thumb:

 

that makes a lot of sense.
