I was thinking I could fill it with rubbing alcohol and shake it then pour it onto a plate and set it in front of a fan until the rubbing alcohol evaporates?
Like he said. Just get some rubbing alcohol and rock salt at the grocery. You can use table salt but it doesnt shake up very well. Put in a little rock salt and some alcohol and shake the hell out of it. Then rinse it really good with tap water. Your glass will sparkle like new.
