Brake cleaner should never be used anywhere near anything but metal and how do you know some won't get dropped where it shouldn't. It should be used with extreme caution and in a very well ventilated area. I have used it as a last resort on one or two machines. Most of the time a machine can be cleaned without going to that extreme. Brake cleaner has chemicals that are considered 'controlled substances' it will eat your immune system/liver. Brake cleaner will eat paint. Brake cleaner will vaporize a styrofoam cup pretty quickly. Be
very cautious when using chemicals. I do not know what was used to melt that gear - it is a machine I bought from
www.shopgoodwill.com - it is always a gamble buying a machine from shopgoodwill - I've gotten stung there more times than anywhere else.
