Use it in a well ventilated area, and ALWAYS have some kind of eye protection if using the aerosol versions (any kinds really, the fumes dry your eyes out and make them sting)
When I used it on my Yashica-C, I just did a quick squirt, freed it right up, and apparently left enough residual lube to keep it running smooth.
My Zenobia, that I just finished with, I really squirted and sprayed heavily, it seemed to run fine at first, but I must have really cleaned it out, because after I loaded a roll, it began sticking and acting badly. I used a bit of graphite and a small bit of sewing machine oil, and worked it until it smoothed out.
The stuff I used is bad for eyes, yes, but even bare skin is a problem, it pulls the oils out of skin almost immediately, and causes chemical burns very quickly. So yep, eye and skin protection is needed! I used a NAPA product.
