After reading on here about the rusting out of vehicle frames I figured I better get to it and do some preservation work on ours. The goal was to clean up underneath and use a rust preventer. I was searching for a cleaner that wouldn't just run off and came across foam cannons. I just took a stab and bought one off Amazon and I just tried it using Dawn dishwashing detergent. It works awesome !!!!! I just wanted to put this out there for anyone, like me who didn't know they existed.
I don't know how to link. Not technically savy at all. You can put "foam cannon" in YouTube and find them though. I bought a Sudmagic but there's a bunch of them to choose from. And they aren't pricy.
No, just cleaning the frame and underbelly. The cannon is meant to be used with car soap but for underneath I used Dawn.
Well if you are savvy enough to put "foam cannon" in google or duckduckgo you can also put "cut and paste URL".
