Cleaning grey tank sensors
The sensors in my grey tank have been working less and less effectively over the last several trips. Now, just after emptying the tank, the monitor still reads 3 bars full. Any way of cleaning them?...

It isn't the sensors, it is crudded up tank walls that fool the sensors. Any thing that cleans the tank walls might help.
I have the TrueLevel non-contact system that Winnebago went standard with in 2005 (right after I bought mine of course so I had to add it) and right now my black tank reads full all the time. The gray started reading 2/3 full all the time few months after I installed the system.
I have pressure washed the black tank wall twice and it worked okay for a while then started reading full all the time.
In my years of trying all of the things people recommend I have not found anything that keeps the tank walls clean enough.
Last summer the rig sat unused next to the house all summer with the gray tank valve open and a hose that drained into a stone filled hole. When we got ready to head south and ran some water, a bunch of dried crud that had been on the side of the tank ran out. Since then (including all last winter) the gray water level has been accurate.
Some people have reported that the HORST MIRACLE PROBES work well. They shield and move the sensors out from the tank walls so the gunk doesn't fool them.
