Review on Happy Campers - Extreme Tank & Sensor Cleaner: Top RV & Marine Cleaning Solution for Unmatched Cleanliness by Dustin Keller

I have to admit my husband was a bit lax about cleaning out the storage tank on our 10 year old motorhome. The black fuel gauge hasn't worked in years. Finally, this summer, snooping turned and I set out to find a solution to the problem. My husband was skeptical but willing to try. Used this cleaner as directed except my husband did not rinse the wand. 1/2 full tank and driven 3 hours (planned). Then I filled the tank to the end and left it for 3 days. Reset to default. No tank smell and my sensors are working! I will stock this product to ensure we never fall so far behind on this service again. It was so easy, I'm sure Hubbie will have no problem with it.
