Unfortunately they did, post #5, first line. I agree with you, unscented Clorox.

Calgon/pine sol

Last summer our black and grey holding tanks became unbearable. All of the store bought rv solutions would not touch the problem. Perusing the net I stumbled upon a mixture the was the answer to our problems. It is a mixture of Calgon and original Pine sol. The tanks are like brand new now.


Fresh water just needs unscented bleach to sanitize at the beginning of the season and a capful when refilling an empty tank. I drink, cook and bathe from the fresh water tank.

Your grey and black tanks are little cesspools that you drag around with you. There are two approaches to maintenance:

1. You use bleach, pine-sol and or commercial tank treatments that kill everything in the tank and dissolve accumulated gunk. Nothing terrible about that unless you dump said mixture into someone's septic system. So many people dumped chemical laden waste into the free dump stations Florida used to have at its rest areas, that they finally just closed them. But it is effective.

2. You use a bacteria/enzyme tank treatment. This introduces non-pathogenic bacteria into your tanks and they chew away, hopefully liquefying all the solids and yuck. It is not as effective as method #1 but a lot friendlier on septic systems you may dump into.

Water is your friend in both instances -- dilution is the solution to pollution. If you have full hookups, I find it helpful to be generous with water and just dump a little more often.
