Review on Cleaner Washing Decanter Kombucha Thermos by Kathy Jones

This brush will not clean the bottom of the thermos or bottle; there are only a few occasional bristles extending under the rounded end of the wire. I have a glass-lined Stanley vacuum flask and I have to be careful not to break the bottom of the Stanley with the metal tip of the brush. I would not recommend this brush for use with glass-lined vacuum bottles or anything that you would expect to do a good job of scrubbing the floor. The sides of the thermos cleaned well. Yes, it ejects a lot of H20 when you take it out of the bottle, but that's because the bristles are pretty stiff and there are a lot of them. Therefore it cleans well (BOCA).
