Removing upholstry stain

["Mike Ross" <mikeross@Prodigy.net>]

Has anyone found a way to remove upholstry stain?  I have original blue MK2
Spitfire seats that have been stained black.  I would like to return them to
the original Midnight Blue that shows beneath the seat frame where a section
of vinyl didn't get stained.
