Grey tank sensors

Hi all, I know this topic probably has been covered many times! I have finally cleaned my black tank well enough that sensors are now working properly. However I can't get the grey tank sensors to read correctly. Makes sense that the black tank cleaned well will get toilet paper and other gunk that are stuck on the sensors to come off and read properly. But what is it that sticks to the sensors on the grey tank and how could we get them off? After dinner we always wipe down our plates before washing!

There can still be a buildup of soap scum, grease, etc that coats the walls of the gray tank. What type of sensors do you have, the kind that stick through a hole in the side or the square plastic stick type on that reads through the plastic side?

I had the same problem with the gray tank on my Itasca, which had the exterior sensors. When I cut a hole in the tank to install one of the Tornado rinse out systems, there was a 1/16" thick coat of gunk on the inside. It took several washings with Dawn and the Tornado system to finally get the sensors to start reading properly.
