Septic tank cleaning product

[tommy the cat]

Been doing some work at the scout camp and want some cleaning product recommendations that are compatable with cess pits as they are not connected to the sewers.
I have no experince with them but know certain products are a no no.
Basically sink and toilet cleaning as well as something to squirt in the boys urinals that will help with the smell

Try white vinegar, the No No element is anything with anti-bacterial chemicals in them and certainly no bleach.
