Tank treatment that can restore sensor accuracy?

I use a toss in packet called commando from Amazon or Walmart. Last day of camping I toss one in and add water to the tank to get it close to full , then drive home. When I dump the tanks the following day the sensors are nice and clean

Thanks I'll try this. Looking at the product description it only mentions black water. Do you use it in the Grey water tank too?

Install a good tank flush if you don't already have one.

Make darn sure your black tank really is empty, look down the toilet to confirm. We bought a used 2018 model and I thought the sensors had issues as I drained the lines myself and nothing more was coming out. First long outing we were full the following day, verified by looking down the hatch, lol. There was the pyramid left behind from purchasing, an issue we had to deal with ASAP. Bags of ice on the way home thankfully loosened enough to drain correctly, then using the factory rinse technique we got it cleaned fully and gauges now work as they should.

Dump a large bag of ice cubes into the tank and drive stop and go for a few miles…

And the Myth Continues :S

I have a feeling anything that would make your sensors work would be something you'd have to do on a consistent basis. Spend enough time in your coach and you won't need them. You'll get a pretty good idea of how long you can go.

DING, ding, ding.........we have a correct answer. Unless one is willing to invest in exterior sensors, such as See Level, this is the best option.

In all my years of camping, I have yet to find that "silver bullet" cure to mis-reading tank sensors...

So far my best solution has been 1 cup of calgon liquid, some dish soap, and about 10 gallons of hot water right before leaving.... let it slosh around and dump/rinse well once I get to where I am going...
