Kitchen Chemistry

Can anyone explain the Chemistry behind this?

Coins placed in vinegar can be ‘cleaned’ but the process takes a relatively long time (you need to leave the coins overnight) but

coinsthat have salt put on them and then vinegar added are cleaned in literally five minutes!

There is some good IB Chemistry at work here ….. but what is it?!
