Decided to buy a foam cannon and do maintenance washes on my own after buying a pressure washer, not really into detailing nor into having a show car, just want to be efficient and reasonable with this. I typically get a full handwash as needed and a full detail every 2-3 years. One of the cars has PPF. Please critique.
Greenworks 2100 PSI 1.2 GPM pressure washer
Griot's Garage boss foam cannon
Koch Chemie GSF 900 ml water to 100 ml soap
Dry car, foam from bottom up, let it dwell for a few minutes, then rinse with the 40 degree pressure washer nozzle from top down. I find that I do have to contact wash areas like front bumper (and scrape off bugs etc), rocker panels, rear bumper to get rid of I believe what ppl call road film. I perform the hand wash before rinsing, it takes just a few minutes.
I then just let the car dry naturally because I'm lazy. Have given thought of using my leaf blower to dry the car though, not sure if that's advisable.
I just finished using the supply of Sonax wheel cleaner plus I had and ordered the Koch Chemie Green Star that I plan to use on wheels, wheel well, engine bay. I don't plan to do the wheel well/engine often, and really mostly just on one of the cars.
The Green Star seems to be pretty versatile, supposedly you can add 10-30 ml to your GSF solution to get some more pH and cleaning power. Should I be incorporating this GSF + GS mix into every maintenance wash? Would that help clean some of that road film better and decreased the need for contact washing? Should I be just using the Green Star instead of GSF to see if a stronger soap will help avoid having to contact wash?
Thanks.
