Re: A question about additives
Atf is also an excellent cleaner if you got something caked with grease oil mess like a bracket that's been subject to years of oil leaking and road grime.... that kind of stuff... soak in Atf overnight. And the stuff comes right off... great for getting sludge out of an engine too.
Another excellent cleaner is wd40 ... I use it to keep the cast aluminum parts on the Harley spotless clean and new looking... a toothbrush and wd40 will get even the nastiest looking cast parts looking great. Wd40 also works wonders for getting rid of decalogue residue or gum in hair or carpet....
