For toilets I use Lysol toilet bowl cleaner I believe it is. I personally am not worried about seals, etc. I flush several times after cleaning, shower is typically used after cleaning, nothing is setting for any period of time and I'm not worried about gate valve seals, they are heavy duty rubber.
We use Happy Camper. Whenever we drain the tanks, and I add Happy Camped to the toilet bowl filled with some water, I use a toilet brush, and clean the bowl before flushing. I use Clorox wipes on the rest of the toilets, and throw them away. On the shower, and bath sinks, we use Scrubbing Bubbles, as it is gentle. The kitchen sink gets Bar Keepers Friend.
