I used to sell auto parts. The regular brake cleaner would hurt natural rubber like what's found on older vehicles. Most newer vehicles, say, after around the early 80's, have mostly switched from natural rubber to things like polyurethane rubber, acrylic rubber, silicon (and flourosilicone) and both regular and hydrogenated nitrile rubber. The non-chlorinated brake clean is safer for these older seals and orings. I would still prefer to use a purpose made chain cleaner, but the non-chlorinated brake clean will work in a pinch. They're both the same thing, but with the chlorinated solvents added, the brake cleaner is much more aggressive. Works better in the shop, but bad for the skin and hard to breathe while using it! Isn't soaking in kerosene the recommended method of cleaning? Yeah, who does that? lol

p.s. If you can even still find chlorinated brake cleaner, keep in mind that in addition to being hard on natural rubber, it also does not play well with paint, or plastic!
