Here's a tip about cleaning the black tank sensors
I like to make sure when I dump my black tank that it is fully empty and clean and the sensors are all working properly. Last time I emptied it, I was unable to get the 1/3 sensor to go off, even after filling and draining the tank several times. Since my trailer does not get moved, I do not have the ability to slosh liquids around in the tank with movement. So I filled the tank about 1/3 full of water, added some holding tank chemicals, and then a dishpan full of hot soapy water (Dawn dishwashing liquid). I let that sit for about an hour and then drained the tank again. The sensor got cleaned of whatever was on it and they are now all reading the levels properly again.
Our dealer mechanic recommends filling the tank with fresh water to third or half, add 1 cup bleach and 1 cup vinegar, take RV for a ride to slosh it around. Won't hurt to dump 5-10 pounds ice in, too, helps scrape the sides and sensors.
