You’ll find many suggested methods to clean out the tank. I had some success using liquid dishwasher detergent. Filled the tank with clean water about 1/3 then put in a large quantity of liquid detergent before driving to the next destination. Did a pretty good job but the sensors acted up again pretty quickly.
Since our sensors are the stick on type that uses electronic capacitance to sense the liquid, I tried decreasing the capacitive coupling. Capacitive proximity sensors are very common in industry, but are adjustable and more robust than the ones on our tanks. I marked the sensor positions on the tank, carefully removed the sensors, and then removed all of the original adhesive tape. I then applied a layer of 3M double sided automotive tape covering the entire sensor surface. The tape I used is slightly thicker than the original adhesive tape thereby reducing the electrical capacitive coupling, thicker tape is necessary, thinner will make the problem worse.
I got very good results from it, the sensors work great and rarely give false readings. False readings now indicate the need for another good tank cleaning. I was considering trying two layers of tape as an experiment, but they are working just fine so that’s low on the to-do list.
