What does RV holding tank treatment do?

How often should you use toilet treatment in an RV?

The black water tank holds water from the toilet, including human waste and toilet paper, while the grey water tank holds water from sink and shower drains.

White vinegar can be used to sanitize and deodorize the black water tank. You can even mix it with baking soda for additional cleaning power.

Given that, it's best to use commercial digester treatments instead.
