Sorry for the misunderstanding. What I meant was while washing.....not rinsing.....you don't want to rub the surface using pressure with your wash mitt.

Using a pressure washer for rinsing is OK as long as you maintain a proper distance from the car, about 4-5 feet, and don't use one with over 1800 PSI.....as mentioned by Kirk, you can cause damage with a pressure washer on certain areas as well, and these should be avoided when using one.

I actually find it faster to rinse off the pre-soak, and post-hand wash with just the garden sprayer attached vs. the pressure washer. So I only use my pressure washer for pre-soak foaming.

You can also do this "soft touch" procedure using Glen's rinseless method, and avoid marring up your paint......spray your panel with a little pre-soak, wipe gently, and roll the towel as you wipe.

Using a lot of pressure doing either method will cause much more marring over time vs. gently removing.
