Bottle Bright - Clean Stainless Steel, Thermos, Tumbler, Insulated and Reusable Water Bottles – Cleaning Tablets are Easy and Safe to Use

Works as intended. Left my bottles clean and shiny inside.

This worked like magic. The first time I did it with water straight from the tap and it cleaned it pretty well still some stains noted. Then I tried with water that had been boiled and forgot about it for 4 hrs, when I came back it was like brand new! Even my husband was shocked at how well it worked and asked me to do it to his travel mugs as well. 100% recommend. Worked fast, pleasant clean low odor smell. No after taste.

Wow. Just wow. I am so impressed with how well these work and how easy they are to use. I’ve thrown mugs away due to what I thought was a permanent stain now I won’t be doing that anymore. These removed years of staining with one tablet.

The Bottle Bright Single Pack tablets are a handy solution for keeping stainless steel bottles, thermoses, tumblers, and insulated drinkware clean. They’re simple to use, just drop a tablet in, add water, and let it fizz! They do a decent job of removing light stains and odors. I found them somewhat effective; they work well for routine cleaning and maintaining freshness, but very stubborn stains may require a second treatment or extra scrubbing. The tablets are safe, non-toxic, and easy to store, making them convenient for regular use. Overall, if you want a low-effort way to keep your reusable bottles clean and odor-free, these tablets are a solid choice. They’re especially useful for quick maintenance between deeper cleans.

I was getting these weird white "waterline" type of stains in my stainless steel coffee tumblers that I couldn't get out. I tried the dollar tree version of these, and the mugs looked clean at first, but when they dried, the stain had returned. I saw the good reviews of Bottle Bright, so I gave them a try. I used boiling water, and let them soak overnight. All of my tumblers look brand new! I love these tabs, and I will never be without them again!

I had three well-used Hydro Flask stainless steel mugs, all with a coffee/tea residue that would not vacate despite repeated scrubbings. I tried these, filled to the brim of the mug, left it overnight, and with basic scrubbing, all the residue is gone! I wish I had taken before/after photos. Totally works and worth the money - especially the value pack.

Shocked how well this gets rid of the brown stains in my coffee carafe and travel mugs. Added hot water, plunked in a tablet, and 20 minutes later they all looked like new.

OMG! This is a great product! My husband and I are big fans of coffee and tea. We use tumblers and thermo carafes all the time. Even if I washed them immediately after use, it was hard to remove all the buildup residue. Especially tall thermo carafes with a small mouth, I can’t wash them even with a bottle brush. After 6 hours soaking with a couple of this cleaning tablets and warm water, most of heavy buildup stains gone! The rest of it, I could washed off completely by rinsing and light brushing. It is effective and effortless! I highly recommend this! One small thing that I want them to improve is the size of tablets could be varied. For example, my travel tumbler is way smaller size that can’t have 1 liter—the amount of the instuction required. I could cut them myself, but it would be clean and easy if it was a half size of the current one. Just a small thought.
