Sudstainables 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

These worked exceptionally well when cleaning out a Camelback hydration vest insert. While the solution smelled a bit minty when the tablet was dissolving, there was no aftertaste whatsoever, and the liquids I put in it were back to tasting normal. They were super easy to use: just drop them in and let it sit for 15 minutes.

Some cleaners take forever to get the taste out after use, but this one is quick and easy. It does a good job cleaning my water bottles easily and quickly without scrubbing.

Worked well at cleaning my coffee cup and water bottles. Takes the odor away from them and cleans them up. Eliminated tough coffee stains in my stainless steel cup. Works well.

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.

I had to use a few tablets but it did the job! I bought a scrub brush for leftover residue and here’s the result. This bottle was filthy and these tablets are the holy grail.

Really happy with the amount of tablets you get in this pack. Actually has a pretty nice smell, nothing overpowering or chemical. Does a good job of cleaning and doesnt leave any residue

These tablets are so great. They clean my bottles leaving them clean and fresh smelling. I originally bought these for a cruise so I could keep my water bottle and coffee tumbler clean. I now use them at home, because I love how my bottles are so clean and fresh.

It took 6 tablets and scrubbing to get it off. I still will use it because it worked to loosen it up a bit. Straight vinegar also works but takes longer.
