So, I tried some of the White Lightning Easy Clean yesterday to clean my chain and drive train -- and I really liked it, it cleaned really well and didn't seem to discolor plastic or anything else it got on.

However, it's really expensive, and I used about $3 of it just for one cleaning and I was pretty frugal with the stuff. Is there a cheaper alternative?

I have used automotive brake cleaner in the past and it works really well, but it seems to be a lot "nastier" if you get any of it on yourself and it would sometimes change the feel of plastic that it got on (which didn't seem like a good thing.)
