  • Very effective
Scent: Lemon Size: 64 Fl Oz (Pack of 1)
Worked awesome. Lovely scent. I don't know how people are having problems with leaking. My bottle was taped so much it took almost 5 minutes to open it 🤣 Was worth the effort

  • Works Will
Scent: Lemon Size: 64 Fl Oz (Pack of 1)
Does a good job. Put it in after every flush out and never have "sower" smelling drains. is worth the little you pay for it to not have "her" bi--hin in your ear about how the trailer smiles.

  • No problems for 2 years running.
Scent: Lemon Size: 64 Fl Oz (Pack of 1)
This stuff is great. Switched to this from Thetford's stuff a couple years ago and been using it ever since. I'm not a big fan of lemon scented stuff, but it's not overpowering. It's subtle and works a million times better than the other name brand. Hope they don't change the formula any time soon as I've had no problems at all with this stuff. ... show more

  • DRAIN SMELLS BE GONE
Scent: Lemon Size: 64 Fl Oz (Pack of 1)
This stuff is awesome, 1 hour after pouring the designated amount listed in instructions on back of bottle, we noticed the smell coming from our RV sink drain was completely gone and hasn't returned after a couple days of usage. I highly recommend this product for your RV, excellent value!

The product itself is great, but packaging sucks and leaked out at least a third of the liquid all over my other camping product I ordered...
