Gray tank cleaner

No matter how hard we try, bits of food end up in the gray tank. That creates a smell, no dish soap will fix that.

But detergent & warm water sloshing around the tank for 3 hours sure does clean things up. I can't see in the tank, but I do know the it doesn't stink. Neither does my black tank after end of season cleaning. At least until the first deposit.
