Review on The Coldest Water Bottle Brush: Ultimate Cleaning Solution for Stainless Steel Bottles - 3-in-1 Tools for Easy and Safe Scrubbing by Rahmayanda Foremaster

I was expecting a thicker brush that could clean my stainless steel water bottles. I suppose if you just drink water from them it might work. Although the bristles on this brush are too soft to remove debris stuck in a water bottle. I used soap and baking soda but the bristles are too soft and not firm enough. I drink tea with tea and this brush is absolutely useless for removing stuck residue. I have another better brush with stiffer bristles that wrap the entire head, but it's difficult to get into the bottle. The ideal brush should have denser and stiffer bristles. I have a brush that works much better than this one. I thought it might be better than mine as it's 3 times the price and people write great reviews. Disappointing to say the least.
