So the whole thing of cleaning wine decanters with steel bearings? We decided to finally try it out. Recommendation: DO NOT USE THESE -- THEY ARE AGENTS OF CHAOS They're actually really easy to use, they clean wine stains off _remarkably_ well, and didn't damage the decanter at all. That part went great. But they are a complete and absolute nightmare as soon as you take them out of the decanter. Have to clean them and dry them, in a little strainer. But they bounce, fly around, are tiny, and get everywhere. EVERYWHERE. Including in your garbage disposal, a remarkably bad place for STEEL BALL BEARINGS. And worse, you may decide to be "clever" and fish them out with a magnet. And then you will have a magnet _and_ steel bearings in your disposal. Which is worse. And you may not find all of the bearings because they are tiny and run away and hide. Until you replace the now useless garbage disposal with a brand new one. Then they will leap out of hiding and jump into the new disposal. Literally before the plumber finishes testing it. The plumber will not be amused. The tiny steel bearings are AGENTS OF COMPLETE CHAOS AND DESTRUCTION, release them at your peril.
