Who has the oldest bottle of Stylast?

I have the same bottle since 1981 or so. Just checked and it is still clear and no crud floating in it. Could this qualify as NOS cleaner with vintage effects? Just think the air in the bottle is from the magic 80's. Well they were magic for me!

Mine is from the mid 80's. Also have record cleaner from same vintage.
Do they gain value with age?
Can I sell them for $200?

Stylast from 1980 and discwasher fluid from 1977 :-)

great vintage... nutty tones with a slight fruity finish

Just having a bottle around doesn't count! You still have to be using is regularly. Even if it's once every-other month or so.

I feel this should be the audiophile "housewarming" gift whenever someone gets their first table.

Here in Milwaukee at the museum we now have a display showing off the Dead Sea Scrolls, and it includes the bottle of Stylast found with the scrolls, which is mostly full yet.
