Bottle Bright - Clean Stainless Steel, Thermos, Tumbler, Insulated and Reusable Water Bottles – Cleaning Tablets are Easy and Safe to UseCompact by Design (Amazon-developed Certification)

The media could not be loaded. This is excellent product. I don’t usually give good reviews but this one deserves it. I wish I took my cup before putting the tablet to clean it but I hope my cup with the tablet and water showed how much stain in my cup. After using the product, my cup is like new and shiny. I am impressed. 30 minutes of soaking my cup is not enough as I need to remove the stain in the rim and upper inner cup. I soak it for 5 hours to make sure it removed all the stain. As you can see in my video, totally clean inside and the rim. Excellent!

I was finally able to clean a glass carafe from stubborn coffee stains that I couldn’t remove before with anything else.I really liked that the cleaner has no smell, rinses off easily, and has a great list of ingredients.

I saw this product (I think maybe on Shark Tank)...anyways have been meaning to buy it to try it out. I really didn't think it would live up to its claims. Most products do not. I bought this during prime day and thought to give it a try. So glad that I did. I use hydro flasks daily. I have all the different sizes. In just one day I will have one to use for water, one for pepsi and one for tea or maybe coffee. So, to try this tablet out I decided to use it on my tea/coffee hyrdo flask. You can easily tell the hydro flask was stain in the inside. The product suggested for heavy stain to leave overnight (so that is what I did). I filled it with hot water, put the tablet in (initially it started to fizzle and overflow so be mindful when filling it up with hot water and put a paper towel under it to avoid spills). I boiled hot water in my water kettle for use so that it was super hot. I left it overnight. In the morning I took a bottle brush and swirled it inside the hydro flask and dumped out the water and rinsed it out. AMAZING! It looked brand new, literally. It was flawless. All stains gone. Metal shiny inside. No after taste after cleaning the hydro flask. I am sold. I had a friend witness the transformation and they were sold on the product immediately and did their hydro flask with the same results. It cleans it so well that you could easily put your hydro flask on a shelf and sell it as brand new, no kidding. So, for this product what it claims to do, it does. Even hydro flask sells only these same tablets by Bottle Bright on their website. Highly recommend.

I'm old school "Don't touch my cup or thermos." So they get pretty bad... followed instructions using hot water. 30 minutes and both are spotless. The dirty thermos water looked like I just brewed a very burnt pot of coffee, and the stainless steel is clean. The tablets work great!

I highly recommend this effective bottle cleaner. The only reason I rated it 4 stars versus 5 stars is because I have to wash the bottle or tea mug with dish soap after I dump out the cleaner because there is a lingering fragrance despite being labeled “fragrance free”. I’m not sure where the fragrance comes from because none of the listed ingredients are a fragrance. The smell and residue to easily disappear after a quick wash with dish soap and it works much better than dish soap alone so I keep using it.

These do not leave any taste or smell (if you rinse well). I use for my collapsible water vest bottles and straws, as well as for the usual plastic and metal bottles. With a very sharp knife, you can cut in half (save the crumbles) and use for smaller containers. My bottles and straws all look and feel squeaky clean after soaking.

I am in awe!! I’ve tried MULTIPLE things to clean my yeti tumblers and nothing has worked. I was super skeptical at first. The first time I soaked my cups together for 20 min. It didn’t work. I decided to give it another shot, but this time I used one tablet in the tumbler by itself with hot water over night. IT WORKED! Looks brand new. I wish I took before and after pics. But I’m a believer!

This is the best cleaner for my hand wash coffee mugs and even my French press and cold brew coffee maker. The fizzing action breaks up any leftover residue with no problem, even on filters. No scrubbing necessary!
