How to clean hair and junk off an auger?

Wrap a rag or gloved hand around it and spin it backward. Or burn it off with a plumbing torch (outside, of course). Or dunk it in drain clog remover for a while.

Removed the toilet from bathrom in effort to get closer to & remove a clog. How do I determine if the clog is gone without putting the toilet back on?
