I kind of do what Nicci does, but not with vinegar - I dump a bucket into the toilet, which lowers the water level without my having to remember to turn the water off/on, squirt whatever bowl cleaner we last bought (Clorox, Lysol, Up & Up, Toilet Duck ... really, I'm not picky) up under the rim, until everything's coated, and let it sit 15-20 minutes before scrubbing.
Hard water stains, I might want to use CLR brand.
