I've tried it, didn't work.  Gauges just don't work, live with it.

Have you tried the "GEO METHOD" of cleaning the tanks? I've used it for several years and it kept the gauges on the tanks functioning correctly on two different motorhomes.

I had stayed at a couple of CG's that had horrific well water and coincidentally my sensors were not working properly. A month later I was going over my RV manuals and came across a chapter on holding tanks and it stated that different types of just water does foul the sensors on the tanks and they said just flushing with water will not restore them, recommending a cleaner.I bought a bottle of it and yes it cleared up the problem.I'm one of the few, I guess, that my sensors work all the time. But I do practice using plenty of water in the black and always running a full tank of plain water thru the black after every dump and I don't put food stuffs or grease of any type down the gray. AND I add a bottle of Thetford sensor cleaner every couple of months to both tanks with a full tank of plain water to remove the minerals off the sensors from CG well water.

I use the Thetford level gauge cleaner in our tanks, but only when getting ready to move the coach.  I fill both holding tanks half full, add the chemicals, then drive the coach to our next destination.  Then I fill the tanks with water and dump.  6 years full-timing and counting and my gauges read correctly.
