Amazing product that brought my stainless coffee mug and water bottle back to brand new.Coffee mug is 23 years of daily use. That before picture is not misleading. It was stained black. I’ve used the boiling water + baking soda + scrubbing and baking soda + vinegar + scrubbing methods before with not much luck.Boiling water + Bottle Bright for 15 mins for it back to brand new. No odors or residue after rinsing.The water bottle somehow got moldy/mildew on it. Boiling water, baking soda and scrubbing couldn’t get it off. One treatment with Bottle Bright and it’s back to new.Just wanted to point out that, as expected, it couldn’t help with the plastic coffee mug lid.Bottle Bright gets 5 stars from me.

I drink lots of tea and coffee from my different Yeti cups, and they’ve developed a nasty-looking tint on the inside that no amount of washing can get rid off. I bought these tablets as a last-ditch effort, with no real expectation that they would work. Boy, was I wrong! One tablet in your cup with warm water for 15-30 minutes, then wipe out cup and wash. My Yetis are sparkling clean once again, and with so little effort. I’m going to now buy a bigger box now that I know it works!

I don't give 5 stars easily. I usually expect some hype in the descriptions. The quality isn’t quite as good as described, but okay. The results are close to claims so we’ll call it good. That's not the case here.I followed instructions and it worked EXACTLY as claimed. I drink a lot of chai and teas and my cup had a brown layer that wasn't coming out short of steel wool, and its a tight fit to scrub so I took a chance on these. There are 2 sets of instructions 1) warm water and 30 minutes or 2) hot water overnight. I chose 2 because I knew my stains were stubborn.The directions said “hot” so I got my hot water directly from the coffee maker and filled it full. The tablet fizzed like crazy and when it slowed, I put the lid on and left it. The next morning I poured it out and, WOW! My cup gleamed like new.My husband tried it next. He’s a coffee drinker. He used hot water from the tap and let it sit 30 minutes. He said there were a few patches left, but they came right off with a wipe of our cup scrubber. He was also impressed. These things just work!I love a product that does exactly what its supposed to do, and I love it even more when I see “Made in the USA” on the packaging. It’s why I tried this brand first, and performance is why it will going on my reorder list!

I’ve purchased these tabs a few times and have had on and off success until now. Wow, did this batch get ALL of my tea mugs, carafes, and accessories SUPER clean!!! It’s easy to wash off, no residue, and no damage to Stanley or Yeti cups and accessories.Maybe I was using expired tabs before, or ones that had become less airtight in their packaging or something? I’m not sure but something was definitely different from the last time I purchased.Either way, happy customer and would recommend!

Make sure you use boiling water with these tablets. It’s so satisfying to watch it start to bubble and then the coffee gunk just starts to melt away! The first time we had these we just used hot water from the tap. The boiling water makes a world of difference.

This is the same product advertised on Today. I love it it's easy to use. I use this in my 64oz water bottle and in our metal BUNN Coffee Carafe. I just use up to 2 tabs in each and it gets all the stains and smells out. Yes, including the coffee stains.

I have cleaned coffee tumblers and even a big carafe and these are excellent. With boiling water from our tea kettle, these have been unstoppable. It does fizz pretty enthusiastically at first, so if you use boiling water be extra careful.

These exceeded my expectations! I am definitely buying more when I run out! I have a Hydro Flask insulated mug that I pretty much either have lemon straight in it or a blueberry green tea. Both stain the inside; the acidity from the lemon tries to strip the stainless steel inside and the blueberry from the green tea turns it dark dark purple that stains on top of the stripping. I do rinse it out regularly and bottle brush it, etc, but never really done a deep clean on it; I've had it for a few years. Thought it would never come back to original, but 3 overnights on 3 tablets, bottle brushed and rinsed out after each time has gotten it to pretty darn near new (lemon is never going to get it to normal) and I'm seriously impressed! I am now doing the lid all taken apart and it's so gross seeing how much stuff is just in the places you can't get to with a bottle brush... I am so very grateful for taking a chance and buying these! I'll do my regular stainless water bottle here soon... Just purchased a new one, so not yucky enough to test it out on that one. Very happy with purchase!
