Tarnished pins, advice needed
Hi guys!!
Last April I picked up some pins on my trip to Disneyland Paris. Since they've been displayed on a lanyard on a hook on my wall. Now I've decided to expand my collection I was taking a closer look at them and it appears they are a getting a bit tarnished, a bit on the front and a fair bit on the back.
Now I think it's because of the environment in the little room we rent (we've had mould issues) and we're moving in a few weeks so that's not a worry, but how can I restore these pins to their shiny glory as when I purchased them? Is there a best way to clean them?
Thanks in advance for any help!
