Why Thetford Tank Blaster – Level Sensor Cleaner – Black Is Necessary
I’ve found that keeping the tank level sensor clean is one of the easiest ways to avoid frustrating readings and messy surprises.

I also like that it saves me time and effort. Instead of dealing with repeated manual cleaning or guessing whether the sensor is working properly, I can use a product made specifically for this job. For me, that makes Thetford Tank Blaster a necessary part of regular RV or portable toilet maintenance.
