Is there a product out there that will clean the monitor inside the
black water tank, it keeps reading 3/4 full but I know it is mty,
or is there something that can be made up, I am a seasonal so i cannot
put something in there and drive it around to loosen it up,
just curious, Thank you.

Seasonal site here as well. Supposedly Happy Camper Extreme Cleaner will work standing but it states not as well as putting it in and driving around. I have bought it but not tried it yet. I ordered my TT and the lights worked once before anything was put in it. I just emptied my tanks and the black/gray both show 3/4 full. I have no faith that the Happy Camper will work. I intend to use it to give the tank a good cleaning on the way South for the winter and if the monitors probes get cleaned good. If not no big deal. The Horst probes as mentioned are supposed to help. The See Level systems that mount on the outside of the tanks are supposedly great but are pricey.
