Late to the part-taaaa here, (sorry, been at the hospital every day for 3 weeks with my MIL). But.... many moons ago it was the gun (back when you could find the Gilmour "Butchers Foam Gun". Shortly after it turned to the cannon as my `go-to`. Drive it with a lil` 1700 psi electric and get excellent results using Megs HyperWash as my main shampoo.
Actually, I`ll mix HyperWash with either Honeydew, Mr. Pink, or Duragloss 902. Don`t bother diluting it either, as `straight up` it tends to give MUCH better foam, and actually use less shampoo.
On my personal vehicles that are all coated, when only dusty (not driven in any rain) I`ll rinse with the PW, foam, rinse, foam, rinse and then dry with the blower. No towels needed.
Of course that`s ONLY if they`re just dusty. If they are *dirty* from driving for weeks, even if no rain, then it`s gonna` take a wash mitt.
