While owning a reusable water bottle is good for the environment, it can be a pain to keep clean depending on the material. Glass and plastic bottles aren’t too hard to maintain, but stainless steel bottles are another story. If you’ve ever owned any kind of stainless steel drinkware, you know how easily it stains and harbors weird odors no matter how much you’ve scrubbed it down. Fortunately, Amazon shoppers have discovered the solution for finally keeping your stainless steel favorites squeaky clean: the Bottle Bright Natural Cleaning Tablets.

The dissolving cleaning solution ($8; works on all kinds of bottles and drinkware made from stainless steel, plastic, glass, porcelain, silicone, or metal. The instructions are simple: Fill your bottle with warm water, drop a Bottle Bright tablet in, wait 15 to 30 minutes (they’re also safe enough to use overnight, depending on how grimy your bottle is), empty, and give it a quick rinse. Just like that, you’ll have a super clean bottle that basically feels brand new, without any effort on your part.

The environmentally safe tablets are biodegradable, chlorine-free, and use all natural ingredients including baking soda, hydrogen peroxide, citrus fruits, salts, and other plants and minerals. Plus, they’re beloved by Amazon shoppers—the tablets are one of the top three best-selling all purpose household cleaners on the site, standing at an overall 4.7 rating with over 800 customers leaving them a positive review.

Bottle Bright Tablet

To buy: $8;

“I seriously can't believe how well these little tablets work. I had the most disgusting Hydro Flask coffee mug—I tried everything. Bottle brush, different kinds of soap, vinegar, EVERYTHING, and there was still a seemingly impenetrable layer of black sludge inside. It grossed me out so much that I bought ANOTHER Hydro Flask to replace it,” one reviewer wrote. “So I tried these little magic tablets. I let a tablet sit in each of my mugs for an hour or two, and the black sludge rinsed out COMPLETELY, without even scrubbing. They look brand new. What a magical product. No weird smell or taste afterward, either.”

The Bottle Bright tablets come in a pack of 12 for just $8 or a pack of 36 for $22. Before you go ahead and get a new bottle because you thought your trusty old one couldn’t be saved, these tablets just might be the miracle you were looking for.
