I have a very handy tool for cleaning Champagne flutes -- the long, slender glasses where it's very hard to reach the bottom of the glass. I think it's made by "Final Touch" but I suspect more than one company makes something similar.
Is there a similar tool adapted to wine glasses and water goblets? It's easier to reach inside those glasses, of course, but the tool still does a better job than, say, a sponge or a wet towel. It's hard to explain but the fabric of the device (it's some kind of terrycloth-like material) really gets anything off the surface of the crystal. I could use the flute tool, but I would prefer a tool that more closely matches the shape of the wine glass.
