Dishwasher Tabs For Black Tank

Like ScottG said, DW tabs need HOT water to be effective. It is also a fairly corrosive detergent and I would be worried what it would do to the rubber seals on the dump valves. A healthy squirt of Dawn dish detergent before you hit the highway with about 10 gallons of water in the tanks will do a decent job of getting rid of any residual gunk clinging to the sides.

DW tabs and detergents don't do a lot in holding tanks because there isn't enough heat to break them down.
You'd also need a ton of them to do anything.

I always wonder the same thing.

Kinda goes along the same lines as never putting toilet paper in it, to never doing #2 in it, to never using it. To each his own, but that's just weird.

I was at a dump station once and just got my BT dumped and all cleaned up. My daughter asked me for the keys to the trailer. You guessed it. She wanted to "dirty up" my BT again. :R

That's why I never use a washer or any of that stuff.

Residual odor perhaps?

No, I use my onboard flusher every now and then.

Do not know the answer but what's wrong with a half cup each Calgon water softener and Dawn (Regular not antibacterial) dishwashing liquid.. THat is the standard.

No need to wait for them to dissolve or if using powdered calgon faster dissolve.
