These stainless steel decanter cleaning balls remove all dirt, residue, sediment and stains from inside your decanter. Simply add a small amount of water to the decanter, place the balls in and move the vessel in a swirling motion until the stains have been removed. After cleaning, place the cleaning balls in a strainer to dry for use again and again. Balls can also be used for cleaning vases or other items with hard to reach areas.
