Rid-XHolding Tank Deodorizer Liquid, Septic Tank Treatment, Fresh Scent, 48 Ounce

This stuff is a miracle. I got something god awful in my grey water tanks and no matter what I tried, the smell was overwhelming. Had professionals blow them out, tried biotics, Chlorox, etc. The smell was like hydrogen sulfide, rotten eggs. Cut my winter snowbirding short and went home and parked my rig. Next spring, odor was still there. Tried this stuff and in 20 minutes, smell was gone. Now I religiously use this in both my black and grey water tanks. Odor never returned.

I continue to use the Rid-X product as I have for over 20 years! It simply works! I've heard all the naysayers and choose to ignore them as this product attacks the solids and eliminates the foul smell of the black tank. Great product!

We was using another brand in our small portable that we kept in the 18 wheeler and RID made the biggest difference and it take like a cap full, so big difference and great smell.

AMAZING! If you’re having doubts, don’t! Just get this stuff and try it out! We live full time in our rv and the smell got out of control! Nothing worked we just had to open. All our windows when we emptied out tanks, this stuff is MAGIC!!! Get a bottle, you will NOT regret it!

Seems to be working on the smell somewhat, but using in our 40 gallon black tank it doesn't seem to help with the break down of the t.p. We are still new to this product so we will continue working with it.

research this any where but on amazons literature it will not break down waste it is only a deodorizer, perfume for the tank nothing more

So far, this is the best product I have found for the holding tank. Tried other products that didn’t work. Hope it continues to work. I recommend based on my experience with it up to now.

Will Buy Again !!!! Fast and well packaged
