What cleaning agents to people prefer to use to clean the bowls of
their toilets, if they own septic systems?


I just use Comet powder and a brush.

Remember, your septic tank holds hundred(s) of gallons of water, and every
time you take a dump the bacteria are replenished. So unless you're
planning on pouring a gallon of bleach down the drain, there's not much you
can do to permanently affect the tank or drain field. Just, as always,
follow the manufacturer's instructions.

Typically 1,000 gal or more. The bacteria in the tank will laugh at the
cup of bleach you use to clean the toilet.
