You know you could probably eliminate this problem if you would, prior to traveling, empty your tank and then add about 5 gallons of water to it. Then add a cup full of liquid laundry detergent (I use Oxy-Clean) and about a cup full of liquid Calgon water softener.
During the drive home, this solution will slosh around in the tank and loosen just about anything in there from the walls of the tank and the sensors.
Upon getting home (or close to home if you don't have a sewer access) and drain the soapy solution and rinse with a tank full of clean water and drain once again.
I always leave several gallons of water in my black tank, even when in storage.
Hope this helps

Agree! This is the absolutely best way to keep them clean. I don't run 5 gallons, I run the water through the toilet for 2 minutes. Add some Dawn Dishwashing liquid (very strong) and drive home. Drain in a bucket if you can't hook up somewhere.
The sloshing when driving is the absolutely best way to clean the inside of the tanks.
