Gray tank cleaner

Not sure you will be shaking the tank enough to mix the gel and water. Why do you need to clean it?

Why not?? I dump about half a small (Dollar Tree) bottle of Dawn in the grey tank without emptying it and then travel for one day to let it slosh around. Once a month or so. No special schedule but some dishwashing grease will accumulate on the walls and eventually will start to smell.

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

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.

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 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.

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

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.

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.
