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

Quick, easy to use and it refreshed my 64oz bottle in just a little over 15 minutes. With the small mouth opening to the bottle these tablets are a game changer.

Works great. On difficult cups and coffee pots I use hot water and 2 and leave over night for great success

These are so easy to use and do a great job! *One nudge- Follow instructions- fill with water before dropping in the tablet.

These cleaning tablets are semi effective. They get most of the stain out, but not entirely. I use them to clean my yeti bottle that I use for hot tea and typically use a tablet to remove stains every few weeks (yes, I do wash in between). A previous cleaning tablet that is no longer available would clean with one tablet. It takes at least two of these tablets to get the bottle clean any inside to its original color.

So far, so good. I've only used it twice, but my husband drinks iced tea out of his "bottle" and it can stain. I threw away his last one because it became so stained and I couldn't get it "clean"

I don't know how anyone using a drink flask gets by without these.I use these tablets to clean my water bottles (even though I use the bottles for tea).They clean them so well, I've started using the tablets for cleaning the coffee cups that the dishwasher didn't get clean, and all sorts of other things. I have them on subscribe and save!

once a week soak overnight and my yeti stainless mug is clean and good to go

These do not do as good of a job as others I’ve had before. They do dissolve well and quickly, but don’t leave surfaces sparkly as some others do. There is not after smell or taste when thoroughly rinsed.
