What do you use when cleaning...

Right... That was my concern as well...

I have a septic & use Tylex with bleach to clean stains from toilets as well as
Porcelain sinks. I also use polident tablets to clean my mouth guards. The tilex is used only when needed, not every week but the polident tablets are used pretty much daily. What do you think?

If you poured two or three gallons of bleach directly into in a septic system you might have a temporary problem. However, consider that once bleach reacts with organics to form compounds, it is no longer active. My swimming pool in Florida got left a couple times and turned green. It took a HUGE amount of chlorine to stop the algae from growing. Consider that a septic tank is FAR FAR "dirtier" in the quantity of solid matter that the bleach can react with and become inactivated.

For toilets? I start with a Haz Mat suit.

Just use the normal bleach sprays for the toilet bowl with a brush to scrub. Should not hurt your system if you only do this once a week. Just don't pour in pure bleach.
