OwalaEcoBrite 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

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!

This is great. Will buy again.You just soak one for 10 minutes or so and rinse.If I have a bunch of dishes I use these for the big bottles, cuts the work load and works great.

These have worked amazingly well for my water bottles. No residue. Worth the price.

These tablets work decently. It doesn't have very clear instructions so I found using boiling water worked best to help the cleaning tablet verses using just hot water from the tap. It gets some stains out if you leave it sitting overnight verses only letting it see for a few hours. The size of these tablets is good for small or large mouth cups. You will need more than one tablet if it isn't being used in a standard size mug. Overall these worked okay but not as well as I'd hope for.

Easily clean long standing coffee stains in our travel mugs!

Plastic water bottles can be a bit of a dilemma. Putting them in a dishwasher may soften or melt them, and scrubbing isn't advised because it creates microscratches where bacteria can breed. These tablets are a nice alternative. I've found the fizz and soak cleaning works well to get spots like the "shoulder" of a bottle (the part where it narrows to become the neck). I've had issues with mold forming there if I wasn't meticulous with cleaning. I haven't had any problems since I started using these tablets. I've also used them on the bladders in hydration packs, although I don't seal the bladder so the fizzy gas has some way to get out. I'm sure it wouldn't burst the bladder seams, but why risk it?No residue after cleaning and a rinse, and no taste or smell that I can perceive. They couldn't be easier to use; fill the container with warm/hot water and drop in a tablet. I don't use them every time as they are a bit pricey, but once a week for a thorough cleaning seems to work well for me.

These tablets work great. I've been using them for thermoses, water bottles and more for at least 10 years now. I feel safe using them, both for myself and the environment. They are also safe for the containers, of course. These tablets have saved me a lot of (useless) time spent scrubbing, and do a better job than I ever could plus using the tabs has been so easy for me! Some items I've needed to do twice to remove all the stains, but I realized I just needed hotter water or in one case, at a new job, the coffee carafe hadn't been cleaned in over five years (before I was working there-yuck !) So, the two tablet treatment took care of it, no problem. Left it with the hot water overnight and it looked like new in the morning.
