Review on 🚽 Thetford 15844 RV Tissue Digestion Solution, 19 oz by Lance Harrison

Poured 1/2 bottle of this into an empty black water tank through the toilet and filled the tank almost full as instructed. I used a hose extension wand to stir/wash the tank by filling it into the toilet through the hose. A few days later I drove 75 miles to a campsite (hopefully throw away well) before draining the tank. The outflow of cleaned water showed that it was "dirty" water and low on paper, but the black water sensors are still clogged. (still shows 3/4 full constantly when lights are on). I can't tell any difference in sensor behavior but the tank drained pretty clean from what I can tell of backwash etc. Note: I also put 1/5 bottle on the gray water tank to rinse it out at the same time as it sensors aren't reading properly either. For these sensors it didn't matter either. Looks like I'll have to try the "Tank Blaster" grey/black water treatment next time.
