Some where I saw someone was using the grunge off product to clean some of their equipment, but I can't seem to find the post again-(forget the search, comes up with too many hits). From what I can find on Amazon the stuff is suppose to be used in pipes for cleaning off the burnt on tobacco grunge from the pipe. Just wondering if it would work with the grunge that builds up in atty's. They also had something called 420 cleaner that may also work. If anyone has tried it, let me know.
