Owala EcoBrite Powerful Cleaning Tablets, Cleans Bottles, Coffee Cups, Pots, Pans, Camping Gear, Pet Bowls, and Much More - 20 pack (Individually Wrapped) Made From Naturally Sourced ingredients

These tablets are awesome! I had been trying to clean the build up on my steel coffee cup, and vinegar barely did the job. I bought these tablets, followed the directions and left it to soak over night. Unbelievable results the next morning. All the coffee stains were gone!! Every bit of it was gone. These tablets work perfectly!!

such a great product and solution for the cups i cant put in the dishwasher

It worked really well on my 30 oz. Stainless steel cups. One that was really stained took a few hours, but the rest about 25 mins.

Recently purchased this cleaner, used boiling water. It removed 100% of years of tea and coffee stains! Definitely recommend and will buy again when I run out. Exceptionally easy to use and worked amazingly well!

These EcoBrite Natural Bottle Cleaning Tablets have made my life so much easier—especially on tournament weekends! I used to pack dish soap and a scrubber in my bag just to keep up with all the shaker bottles, tumblers, and water jugs my two teen athletes go through. Now? I just bring a few of these tablets and I’m set.They dissolve quickly, clean thoroughly, and leave no odor or residue—even after bottles have been sitting in a hot gym bag all day with leftover protein shake or electrolytes. It’s honestly amazing how fresh everything smells afterward, without having to lift a finger.I also love that they’re chlorine- and phosphate-free, safe for stainless steel and plastic, and made with natural ingredients. We use them in everything from Owala and Hydro Flask bottles to shaker cups, and they’ve never left a weird taste or caused any damage.These are a tournament weekend must-have and a total time-saver at home too. Please bring them back in stock—I want to buy in bulk!

Works ok but very little product for the price.

I have a Yeti stainless steel tumbler that I use constantly. I use it so much that taking the time to clean it is difficult because then I am without my tumbler.I wanted to try these tablets for cleaning. Generally, I just put my tumbler, straw, and lid into the dishwasher. I tried these tablets, followed the directions, mixed with hot water, and let sit for a few hours.The result was that the tumbler did, indeed, look clean.However, I am not sure if it is actually sanitized, which is what I wanted.I didn't notice a smell to these, and they really did put a good shine on the inside of my tumbler. Cleaned the lid and straw, too. I made sure to rinse thoroughly before adding my filtered water, and I didn't notice any aftertaste.Each tablet is individually wrapped, so these are great for travel when you don't have access to your dishwasher.Not sure these are worth the price, though, as I am not sure they do anything my dishwasher doesn't do.Four stars.

These worked wonderfully getting rid of all the built up iced tea stains. No leftover residue and no scent. These are well worth it.
