The plus side is that it evaporates very quickly, so you can work out a system of using just enough to 'cut' into the dirt and getting it off quickly without dousing it or leaving it on for too long. I find it quite easy to be judicial about these things and am quite light handed (and have good eyesight) but of course, I would never recommend it to someone with a machine with decals or japanning. Stay away from any writing on yours with the alcohol if you decide to try it.

...and good luck! Beautiful machine. I'm jealous
