My general understanding is that crystal should never be allowed to have
wine rest for a long period of time. Crystal is not a smooth surface, and
your bound to get stains. This has happened to my Riedel Sommelier series
glasses (well at least one or two) after I left some heavy reds overnight.

The torture of using a cleansing product is that it is likely to embed in
the crystal the same way the wine has embedded. The best suggestion I read
might be the rice and vinegar. Personally, I would pick a $2 wine and rinse
the decanter several times to get out any notion of a cleansing product.

My number one decanter issue is drying . Still haven't done my better than
hanging upside down and letting nature dry it out.

good luck cleaning.

I decanted a bottle of Fonseca Vintage Porto, thinking that I would be
able
to enjoy this with guests as they came over during the holidaze. We
finished
off the last of it but my decanter has a heavy layer of sediment along the
sides. It's a hand-blown port decanter that defies my getting a barman's
mop
inside. Can someone suggest any other ways of cleaning the inside?

Note: I've let it soak all day with mild soap and hot water. The sediment
laughed at that attempt.
