Gray tank cleaner

Bleach. But be careful not to mix it with commercial additives. I put bleach in the traps occasionally to keep out odors. Nothing else.

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.

I used the Flush King to back flush the gray tank system. Always pulled things out of that tank without adding anything to the system. have a clear down spout to let me see what was coming out. Did it about 2-3 times a year.

Reminds me to work on uncle's gray tank. We Will work on it after we finished installing the shocks from 4Wheelonline onto the Wrangler JK project. The gray tank starts to smell bad after a couple of years. Will try Flush King.

I use nothing, never had a problem.......

Many of us wash the dishes with Dawn or similar - that should be sufficient to keep grease etc from building up in the Gray water tank.

I put in about 2 cups of liquid laundry detergent in each of the gray & black water tanks & fill them about 1/2 - 1/3 full for the final drive home at the end of camping season. For the galley tank, I empty the hot water tank into it to help break up the nasty kitchen grease.

I prefer the HE laundry detergent because it is very low sudsing and so drains more completely.

I use u digest it. Best tank cleaner I’ve used.
