RV Toilet Treatment – Gray & Black Tank Treatment, Holding Tank Digester for RV, Camper, Boat, & Porta Potty – Extra Strength Odor Eliminator | Fresh Scent (64 oz)

Does what it says! I've used a ton of different products & this one works the best! I use it in BOTH our RV black & gray tanks. Its the only product that cleans the sensors, makes the cabin smell FRESH & prevents that embrassing order from escaping when you open the tanks to drain.

Recommend for campers!

This product did reduce odor in my camper but personally, I'm not crazy about it's fragrance. It's better alternative though.

Really does work.

Smells good and strong just doesn’t last , flushed our tank out with bleach, soap and high pressure water , added water to the tank then the blue deodorizer and it smelled great for the rest of the evening but the next days afterwards was just normal , which is not bad I was just hoping it would last a little longer because of the way it smells at first . I would recommend it.

The image appears larger online than it does in print, which is disappointing considering its price.

have been using this for a couple of tanks, this product works as described, keeps the smell down better than what i was using before, tank seems to come out cleaner, i am going to see how it works over time but so far i am impressed,

Great stuff will definitely buy again thank you great price
