I wear gloves as well, as it will degrease the oil right off your skin as well, leaving it dry and chapped. Also, clean heavy grime off first with a paper towel or rag, as it doesn't simply dissolve heavy grease. It will just make a mess of it. It does, however, do a good job of getting grease in hard to reach places. I also rinse with water after cleaning parts, especially if they need to be regreased. I've found it also does a nice job on white brake hoods, though maybe it's damaging them in the long term?

I actually prefer mineral spirits to clean parts, because I find it requires only a small amount on a rag, rather than a good spray or two of SG, and it will cut through grease more efficiently. Mineral spirits have a bit more fumes, however. But, honestly, I can't stand the smell of SG. I believe one of its active ingredients is ammonia, which smells nasty to me. Reminds me of cat piss.
