Water Bottle Cleaning Tablets – 36-Pack, Chlorine-Free and Odorless Cleaner for Hydration Bladders, Stainless Steel, Tumblers, and Glass Bottles - Removes Stubborn Stains and Odors

Works great! I've tried many brands of this type of product. This is my favorite! It works well, removes stains and any funky smell or taste. I've used it on my Yeti tumbler, metal waterbottle and plastic waterbottle. It doesn't have a lingering taste or smell after. When its foaming up during use it has a fresh/minty smell but it isn't overpowering (I'm sensitive to smells). Definitely recommend!

These tablets do a great cleaning on hydration bladder and tube. Easy to use, works quickly.

This product works perfectly!!!!! It completely gets rid of that old protein shaker bottle smell and taste. I’ve given a few to my wife and a couple friends to try and everybody all says the same thing that it worked great for them and that they’d be looking to purchase their own soon. I also feel that the price is great especially for how many you get and the ease of use. I have tried many other methods to try to get that nasty smell out of my gym bottle and some would work better than others but ultimately not get the job fully done. These tablets work so well that I can actually drink water from my shaker bottle without it tasting funky. I will say make sure you rinse your bottle VERY well after using one of these tablets. I made the mistake of not doing so once and it left me with a weird taste in my bottle that wasn’t pleasant at all. But like I said as long as you thoroughly rinse you will be fine.

Works well but will try to find a different brand next time as these are leaving water spots on the inside of my stainless steel bottles. Water spots aren't a big deal, obviously, but we have very hard water and might need something stronger so that when the bottles dry there's nothing that looks dirty still, and definitely no residue left behind.

These are amazing!! Not only did it remove stubborn stains, it also got rid of the mold I had in one of my cups! (I know, gross! Don’t judge lol) it effectively cleaned all of my cups so well in fact, I bought 3 more packages. I love that is less expensive than the name brand, but still works wonders.

Worked great! Got stains and other spots off on the first try.

Several years ago I got some cleaning tablets to clean my stainless steel jugs.They foamed up and within 15 minutes, cleaned all the crud out of my jugs.They worked beautifully on my pans as well.These just sat there and did practically nothing.They might have helped loosen things up but definitely not the ones I bought in the past.Disappointed with the results.Guess I need to find the ones I got before.Hopefully others had better luck.

Easy to use . Tablets are individually wrapped . Used the tablet as directed for 15 minutes but did not really clean the coffee Tumbler ( the coffee tumbler was really stained .) Tried a second tablet and let it sit for about eight hours and that did the trick! the coffee Tumbler looks brand new inside. So depending on how stained your Tumbler is would depend on how long you would let it sit. I am pleased with this product. Worked effectively .
