If I recall, CMT is also sold at Menards?? I use the citrus degreaser to clean blades and bits as well if I'm out of CMT. I never noticed the "do not rinse" part of the instructions. Of course, that's probably because I didn't read them.
Boeshield Rust Free and Blade and bit are decent as well, but more expensive. I like Boeshield Rust and Corrosion for anything that squeaks.
Bostik Glidecote is really good for cast iron surfaces. It seems to hold up better than paste wax.
