Review on 🧼 Bottle Bright - Powerful Cleaning Tablets for Water Bottles, Containers & Hydration Packs - Fresh, Clear & Chemical-Free by Carrie Porter

My husband and I have 16 ounce HydroFlask cups for coffee. Mine wasn't that bad, but my men were terrible. I've tried vinegar, baking soda, etc., and while some of these work, not all. I stumbled across them and saw all the good reviews so decided to give it a try. I filled each cup with hot water and dropped a pill into it. I let it sit for a while, maybe an hour or so. When I threw out the water, all the dirt went with it. The inside of the cup looked like new. The husband thought it was a new cup. ;) I'm SO happy with these little gems. I have only used them with a hydroflask but I am so happy with the product and the results!
