I liked the way it cleans. It is easy to use. It could have some scent. What's there was I could not detect. I don't think it had any scent.

When I received this order, it was not packaged the same as the photo used when I made the purchase. In fact, it came in a clear thin zip bag with a white label on it identifying the product. The packets of the stuff are in genetic-looking paper-like packets. There were NO instructions in the package or on the box it came in. The printing on the packets are so blurry they are unreadable.

Thankfully I took a photo of the printed package directions with my cell phone. I was able to enlarge the instructions and could BARELY read the instructions. I'm so glad I did that or I might have opened one of the packets. You do NOT open the packets. You run hot water for at least a minute and then keep a pencil-thin trickle of hot water flowing when you put one entire packet, in it's paper-like wrapper, down the disposal and turn it on.

Stand back! It begins to foam and sounds like the sink might take off in flight. The drain on the other side of the sink starts slowly bubbling up blue foam. Holy blue foam, Batman. Lots of blue foam. The sound subsides and the disposal sounds like it normally does and then you can turn off the disposal.

I used hot water to rinse the blue foam out of the drain on other side of the sink.

The sink flap on my disposal is not removable, and I suspect the stink in the sink is because the underside of the flap is way toxic since it's impossible to clean. The blue foam inundated the underside of the sink flaps, so I'm hopeful this will eliminate the stink.

This was an impressive and a little frightening product the first time since I had no idea what it would do. I'm hopeful the stink in the sink will be gone. I gave 5 stars, assuming it will work, since it's such a powerful attempt. I'll revise if, as the week progresses, it has not done the job.

I'm not 100% sure this product is absolutely necessary, or if you could get similar results from some sort of diy thing but.... these are seriously fun to use, and pretty helpful.

I like that it creates a super foam that can clean both sides of that rubber thing. I feel like that rubber thing is where ick hides. This stuff isn't at all a perfume to just mask or neutralize odors. The foam seems to actually clean the slime off of stuff. So that your sink smells clean because it IS clean.

Im kind of particular about the kitchen sink. They're seriously like the 2nd most disgusting place in the house. Using these once a week, in addition to keeping the rest of the sink sparkling, you could almost eat off my sink. Except I wouldn't. Because sinks are still gross.

This is the first time I have purchased a garbage disposal cleaner on Amazon, though I have purchased them for years at my local supermarket. I believe Glisten may have been one of them because one was supposed to have blue foam emerging from the unit into the sink.

Several reviews indicated that the blue foam that is supposed to emerge from the garbage disposal soon after inserting Glisten never reached the top of the drain, where presumably it cleans the lip of the garbage disposal unit. Although I associated these reviews with my previous with a garbage disposal cleaner, I took a chance and ordered it.

I have now used the first packet from my order and it worked like a charm. I followed all the prep instructions exactly, and the blue foam emerged from the disposal as expected. Unlike other products that have instructed some type of foaming action would continue for two minutes but fell far short of that, Glisten came very close.

So , in my first use Glisten performed with flying colors. This would suggest to me three possible reasons why some reviewers didn't have the same experience. First, there may have been a quality control issue in the manufacturing process that has been resolved, at least for now. Second, these reviewers may not have prepared the disposal for use according to the manufacturer's instructions (e.g., running warm water before inserting the packet or running too much or too little water during the cleaning process). Finally, it's possible the product may deteriorate over time if not properly stored. Although the outer package is resealable plastic, the individual packets are made of a degradable, septic-safe material that is far from moisture-proof. Consequently, I am storing the opened plastic package inside a zippered plastic storage bag just to be safe.

If I find quality issues with the product moving forward, I will update my review. But as of now, it has worked flawlessly.

My garbage disposal has had a rotten odor coming from it since I moved in and I'd tried at least a half dozen other things, multiple times, before finally stumbling across these. I was hopeful based off the other reviews, but also being realistic considering the failures of everything else. The first packet went in and after it was all rinsed away, the smell was instantly better, barely noticeable unless I really leaned in to check for it. So, I ran a second packet through, and haven't smelled anything since then.

I would definitely recommend taking the time after using these to clean the underside of the rubber bit. I'd cleaned it with other products numerous times while trying to get rid of the smell, but when I cleaned it after the second packet, massive amounts of nasty gunk came off with barely any effort. I'm guessing whatever was in the foam broke all that down and made it finally come truly clean.

The product smell from the packets does go away fairly quickly, but it definitely wasn't there as just a cover up. Because after a year of dreading the stench every time I had to use my sink (and being embarrassed about friends and family going in my kitchen because of it), this product has made it completely odor-free!
