EcoBrite All Natural, Powerful Cleaning Tablets, Cleans Stainless Steel, Tumbler, Insulated, Reusable, and Plastic Water Bottles, Chlorine and Phosphate Free (Pack of 20)

Easy to use, cleans all Owala bottles and cups well, no residue left, and great value and quality.

Removed stains with ease! Does not leave after taste in the cup yet it is very effective and affordable. I got this for all of my siblings as I had gotten them cups for Owalas for Christmas, they all loved them. Very sturdy and tasty.

I bought this to clean out my coffee cup that hasn’t come clean for a couple of years even after putting in the dishwasher. The coffee stains just seemed to be embedded in the metal. So, I thought I would give this a try. I boiled the water so it was very hot, dropped in a tab, and let it sit overnight. Super easy!! Amazingly, when I poured the water out in the morning, the coffee stains had separated from the sides. I washed the cup and it is now all clean, bright and shiny - just like new! So excited and super glad I gave these a try! Highly recommended and worth every penny - you won’t be disappointed!!

Cleaned a coffee mug that another product didn't even get a little bit clean.

I have had a few different bottles that I haven’t used as they have had a smell and taste to them for a while. Nothing I have done to clean them has fixed it. These tablets did the job and I know get to use my favorite bottles again. Will definitely buy them again as they are a great value.
