Is it safe to use a vintage salt shaker with a silver cap that has turned green and a bit rusty? How do I clean it?
It is not safe to use the vintage salt shaker with the rusty cap. The rust might contain bacteria that are harmful to the human health. You can sterilize the cap or get a replacement from a store with similar commodities.
Viniger i think to clean it
Bar Keeper's Friend will clean it right up.
If it's rusty, it's not silver. It's probably chrome plated steel.
No, it's not safe & it's probably not silver! Don't use it at all!
You can clean the top with metal cleaner and use it.
