Wish I had known on March 29,2008 what I know now about Ballistol.
I had a fire and about 150 rifles and 30 pistols were covered with a black smoky plastic like covering.
WD-40, naptha, acetone and paint stripper wouldn't budge the soot and whatever was in it.
A couple of months later I read about Ballistol and decided if it was good enough for the German army
to clean their black powder rifles with, it might do the trick.
I ordered a 5 gallon bucket of it and have been busy cleaning ever since. Molds, dies and everything responds well to it.
It does not harm plastic, wood, paper etc., but I don't use it on leather, using Pecard antique leather cleaner and conditioner.
So, if you ever have something 'harmed' by whatever, I'd recommend Ballistol.
I bought mine from Wiseman Trading FWIW. $245/5gal now-WOW.
