#7. Restore shine to coins and jewelry
Coins and jewelry that have started to gather an unsightly tarnish can be cleaned with nothing more than a can of Coke. If you care about how shiny your pocket change is, simply drop the grimy coins in a Coke
bath and leave them overnight. In the morning, pour the Coke down the drain, rinse the coins in warm
water and pat them dry. I grabbed a handful of grimy pennies and nickels, dropped them into a cup of cola and let them sit overnight. The acid in Coke can also strip paint and rust off metal if left long enough.
Remove the jewelry and promptly rinse. For something a bit safer, you may want to stick to cleaning
jewelry with aluminum foil instead.
