Big difference already. I had to use two cans of Gunk foamy engine cleaner followed by Scrubbin' Bubbles (Dow bathroom cleaner). Then cotton shop towell wrapped around a sharpened piece of wood to dig into the fins on the bottom. I was getting it ready to paint, though. Once assembled, it really does make a difference. I did like you on the '79 last summer, and it looks so much better.
Yep, I'll clean it up as best I can without going too nuts, this bike isn't a show bike it gets ridden hard all season in all weather, it will be filthy again the first time I get caught out in bad weather.
I got some of that but I can't use it in the basement. I'd get shot. I'll hit the lower half with that outside later in the spring when I can hose it off after etc. It is good stuff for de-greasing engines.
