Review on ECOAND Water Bottle & Tumbler Deep Cleaning Tablets - 🌱 Biodegradable, Odor-Free for Stainless Steel Drinkware, Baby Cups, and Accessories (2 Box) by Tania Swenson

I really didn't like the fact that there were no instructions in English and no list of ingredients. Everything on the packaging is in Korean... luckily I can read Korean! Basically it says to mix it with 400ml of hot water with one tablet. So if you are cleaning a large water bottle, you will most likely need 2-3 tablets to clean just one bottle. dissolves quickly. Then when it all dissolves it becomes a slippery liquid with a very strange odor. I washed 4 water bottles with it. A plastic Tritan, one and three by Takeya with a stainless steel interior. None of them looked super clean or special afterwards. Maybe my bottles weren't dirty enough since I only use water and not the tea or coffee in those bottles. Basically it was like I just washed it with regular soap and water. This helped clean my water bottles, but I had to rinse and wash them again because of the weird smell I mentioned earlier. They are travel friendly as they are individually wrapped which is great if you travel a lot.
