Best way to clean Toto Drake

The instructions for our new Toto Drake said not to use in-bowl cleaners because it could damage the fittings and said not to use chlorine products. Being somewhat of a germ freak, I had always cleaned my toilet bowls by pouring chlorine bleach in them and scrubbed them all over, let the bleach sit for about 5 minutes and then flushed. (I wonder if I was damaging all my old toilets?) What do all of you out there use to keep the bowl and under the rim clean and sanitized?

I've been using Clorox Teflon bowl cleaner.

Same here. I do the bleach thing sparingly about 4X per year only.
I also use CLR every couple months...or as needed.
