Grey Water Odor Control - RV Grey Water Tank Treatment, 24 oz - Thetford 15842

Works well in gray tank for RV. No odors. Will buy again

This stuff works. We suffered for an entire Texas summer in our RV before discovering this stuff. Now we use it in the sink and bath tanks liberally combined with the regular pod / chemical you use in those tanks and even in the dead of a southern summer there are zero smells. The cost adds up if you use it liberally like I do, but again, it truly works. I just can't deal with grey water smell. Now I don't have to ever again. Win.

Seems to work. It gasses off this weird smell during treatment tho. It's only noticeable if you leave your RV for awhile and come back, in minutes it's unnoticeable as you get used to it. Love thetford products and wish I could give it 5 stars, but that smell was really strange. Was gone after dumping thankfully. At least it does seem to get rid of that nasty old grease smell, so it could be worse.

One of the best on the market, easy time use does a great job of keeping grey tank from smelling and helps to keep sensors working well.

We have always used this product with our RVs and we have never had an odor issue until the time we ran out on a longer trip. Definitely noticed the difference without it...yuck! And I am very careful about what goes in our tanks. We had to use Tank Blaster when we got home to restore them to their clean condition. So this year, I bought two bottles for our rig. Prevention is always better than having to cure the problem.

In a very hot environment, the grey tank needs to be emptied almost daily so the soap, etc film doesn't build up on the walls of the tank. Unfortunately, there were times I forgot about emptying and let it get to 2/3 full. Now, the tank stinks like rotten eggs so bad I want to pass out. This product did work on the initial use. However, you have to keep using it and it doesn't do anything for the walls above the storage or the top. So, I am researching stronger ones and will probably not buy this one again. Just not strong enough - but it does work on a very short temporary basis.

Works as it should!

works to help with gray water smells.. been very happy..

Plus d'odeur instantanément. Beaucoup de résidus lors de la vidange suivante. Nettoie bien les conduits.

Good product, worked as decribed

Works great in our camper that consistently has smelly water. Just a little down the drain and no more smell.

bought this to help mask the odors from the sump pump and it works! will be buying it again.

Works perfect in the RV grey water holding tank. It’s quite concentrated and has a pleasant smell. Have never had any issue with smelly tanks. A+
