Fresh scent works quickly

I tried putting liquid plumber down my drain and draino to cure the smell. Then after weeks of that not working, I tried baking soda and lemon that did not work. The only thing that could seem to cut the smell of old drain was this stuff! I poured it down and it smells pleasant. I rent so I can't go underneath my sink or hire a plumber to come in and fix the stinky drain in my kitchen. I suspect that I'll have to repeat it in a few weeks but that's OK. At least now I could walk in my kitchen and it smells like fresh lemons.

Works in grey tank, not so much in black tank

I bought thins thinking it was for camper toilets and it is not. But too late, already put it in the toilet! It still does the job of fixing the smell but it definitely wears off quicker in the black tank. Thats how I fou d out it was for the grey tank. Is strong enough and works very well in the grey tank. Keeps the smell down for almost a week in the grey, and about 2 days in the black tank. I don't like the measuring and so I always just guesstimate.

We like using this product for our gray tank on our rv. It keeps the tank from having a bad smell from food particles and stuff. Also, it's a good price and lasts quite a while.
