Should vintage aluminum cookware be ckeaned for resale?

[Nickleanddime]

I find alot of older wear-ever cookware and other items. They are usually tarnished or stained. So should I clean and polish the item before resale? Also glass pie baking dishes a good buy. Also what about Tupperware? I'm trying to expand into different more useful items to sell. Thanks everyone.

Yes Vintage cookware should be cleaned before resale.if it's still useable.However if it's a very old item sometimes collectors like the old look.
