<[log in to unmask]> =====
>Dear Listers,
>
>Does any of you have experience of removing chewing gum from an
>antique rug? This is a growing problem in our museum, where the
>original rugs have to be kept on display - regardless of their
>conditions. I was wondering whether anyone can suggest a simple
>way of getting rid of the unpleasent stuff. I know that freezing it may be
>an option, but I am hoping there might be an easier option.
>
>Thanks for the help.
