Topic: Cleaning decanters

Paul, I also wonder which glass is more prone to this than other. Which vintage? Which composition? Just posing questions - I don't know. I have glass that is quite modern that has it and vintage that has it. I see no correlation, certainly not in my collection.

Hi Julie  -  regret I've no skills in the area of chemistry, so unable to comment in a useful way............    suspect that whether or not there is staining is dependent of a variety of things, and it's not just one factor that's responsible.               I've had late Georgian bottles that were as clean as a whistle, and some made well into the C20 that had a cloudiness that defies removal, but it sounds like a good subject for someone to delve into.

quote........    "which vintage?"  -  I like your pun -  do you think a famous vintage might give a better sort of staining?
