I would be a little hesitant to use bleach that is called for in the GEO method. I may be wrong, but I don't think it would be good for the valve rubber seals.

I use a CAP ful of Calgon Liquid and a CAP ful of DAWN Liquid Dish Soap about every third tank. I also have the Blue Streak which injects the perfect amount of tank treatment with EVERY flush. Been doing this for years with great results.

I use the super cleaner too but I also put in a 10# bag of cubed ice before hitting the road. About once year it does a good scrub jobl

An unexpected benefit is that since the TT now glows brightly in the dark, it's really easy to find our campsite at night

I think the black tank already has nuclear waste in it. 😷

If you use superclean in the blue streak it is no longer a blue streak? Should be a Super Streak. Pine sol works good in our tanks.

I have always been afraid to use strong chemicals in my holding tanks, not knowing what effect they would have on the seals. I prefer Kronen Holding Tank treatment. It's got the microbes in it like the municipal sewage treatment plants and doesn't have the strong formaldehyde odor that a lot of tank treatments to. I also use it in my gray tanks to help keep them clean, especially the galley tank to keep the soap scum under control.

Clean water after flushing/ emptying the tank. add some more water, about a quart and put a squirt of dawn in there, so on the way home it will clean the tank.
