I bought a pressure washer for H2

I've always owned a pressure washer. My current one sound similar to yours. Personally I have never had great luck with the soap mixing systems if you want to call them.

It's basically just a hose that used the water pressure to siphon the soap in. I use a big soft scrubber on an extension pole and a 5 gallon bucket of car soap and water to wash. Pressure washer before to get rid of dust and after to get rid of soap.

Spray applied wax will do nothing. It may look shiny when you're done but it's not going to last.
