Review on Holikme 5 Pack Bottle Brush Cleaning Set: Efficiently Clean Narrow Neck Beer Bottles, Wine Decanter, Cups, Pipes, Hydro Flask Tumbler, Sinks, Cup Covers - White Long-Handle Brush Cleaner by Dean Wildfang

I have about a dozen 20 ounce metal water bottles that I use for everything - they are literally the only "cups" I use. But the bottom of them gets gross, especially if you use them for tea. I bought about a dozen brushes to clean them, including brand name brushes from a company that makes bottles, and they all suck a little because the twisted wire handle doesn't so is strong so you can actually clean the bottom of the bottle.The blue bristle brush has a metal handle strong enough to clean things with pressure and that all without just bending in half. It's not ideal - I wish the bristles were a little stiffer, or that the bottom one was more like a circle so the edges of the bottle were lighter, but it's a huge improvement over other brushes I've used. Daily use and the Bottle Bright tabs about once a month just to really clean things up made my water bottles a lot less disgusting and saved a few I thought I'd have to throw out. The rest of the brushes aren't bad either - the white foam is an oddly dense suds, but surprisingly effective when you don't need to scrub thoroughly but just want to rinse the bottle between uses. The straw cleaner is wide enough to clean the sides of a straw and long enough to clean even my tallest straws. The only brush I haven't found much use for is the loop brush. I think it's for pop-up mouthpieces, but something with the shape doesn't quite add up, at least for the bottles I have. But to be honest, I'd pay ten bucks for just the blue brush. great set
