I have discovered a great two-step process that saves lots of time and elbow
grease when doing a thorough restoration on Gottlieb pins with copper plated
parts.
First, soak the parts in a solution of 'Zep All-Purpose Citrus Cleaner' and
warm water. Follow the instructions on the bottle. The 'Zep' does a great
job removing most of the tarnish and the factory coating that I suspect was
applied to retard tarnishing of these parts. Do not soak the parts any
longer than 4 hours or so; if you do, the plating itself will start to come
off! Remove the parts from the solution, rinse them under warm running
water, and set them aside to dry.
Next, polish the parts with 'Mothers Mag and Aluminum Polish'. This polish
will restore the copper plating to an incredible shine and luster. It
doesn't take too much rubbing, since most of the gunk was removed by the
solution in Step 1. You can find the citrus cleaner in large 'refill' size
bottles at Home Depot. The polish can be found in the 'waxes and polish'
section of most good auto stores.
You'll be amazed at how great these parts come out using this process.
