Worked In Our Bathroom Drains

We occasionally noticed unpleasant odors coming from our bathroom sink and shower drain, especially on warmer days. After using the HDJ Drain Odor Eliminator, the smell completely disappeared, and it has remained that way for the past three weeks.
The instructions recommend using 0.2–0.24 liters per treatment, which is about a quarter of the bottle. However, I used roughly half that amount and still achieved great results. Going forward, I plan to use smaller amounts regularly as a preventative measure to maintain freshness while making the bottle last longer.

Worked awesome for our kitchen drains after multiple products failed.

We had an annoying odor coming from our kitchen sink piping and garbage disposal. We tried other options similar to this and the pellet style and none of them worked for more than a day. I mixed this pretty heavy and really made sure I sprayed it good into the drains and the garbage disposal unit and then let it sit overnight. After sitting overnight it had removed most of the icky stuff I could see and definitely flushed the horrible smell out of the system. I can't say that it's draining any better because we didn't have that problem to begin with, but surely getting rid of the gunk on the insides of the pipes definitely helps. The main thing is that the product works fabulously for the reason I got it and that was to remove the drain odor. It has been over a week since I did the treatment and it has not come back. Wish I had got this the first time, because we spent 10 times the amount of this on all the other things we tried. This is definitely a bargain because it actually works as good as it says it does and it's super concentrated so you can get a lot of use out of it.

It works!!!!

We've smelt such a foul odor coming from our drains for a while. It was only present once you turned the faucet on thankfully was but still very noticeable.

We poured this product down both our dual sink drains and let sit for a while and the smell disappeared!! And it smelt so clean and fresh. The red coloring didn't seem to stain at all either.

We let it sit for about 15 minutes. We used both sinks very frequently and the smell hasn't returned at all. The instructions state to pour about a fifth of the bottle per drain so we even have more than enough left over for upkeep! Well worth the price.

Musty laundry room smells are gone

Got this for our laundry room where the sink and floor drain had developed a musty odor. Poured some in, let it sit, and the smells are completely gone. The cherry scent is pleasant without being overpowering or artificial. Nice that it's biodegradable and actually treats the buildup instead of just masking it. A little goes a long way since it's concentrated. Will keep this on hand for regular maintenance.

Seems to work well

We have one sink and shower that always seem to have a foul smell. We've tried various products but they have never seemed to solve the problem for anything more than a few weeks. We're hopeful this product will do the trick as it is unlike any of the others we've tried. The product is much thicker than we're used to, and it does have a slight "fake" cherry scent which isn't bothersome at all. After pouring it down the drains, we waited several hours and then flushed it down. It definitely remedied the immediate smell but we will have to wait a few weeks to see if it comes back. We're hopeful it does eliminate whatever organic matter is causing the smell!
