Help with cleaning up chrome on Jetfire

[Optimus Maximus]

I got a complete jetfire in over all good condition but it has one problem. The chrome or bare metal parts are corroded. I was wondering if anyone else has had this problem with Jetfire also? If so does anyone have any ideas how to clean it up? Here is a pic of the upper hip joint. You can notice its turning green and flaking.

I've had that problem with metal pieces too. Also on screws and pins. THe screws normally rust, but the pins almost look like they mold.

I've not found anything to really clean it. I've found goo gone can take some of it off. But not all by any means.

I've actually used goo gone to clean out the battery compartments after the batteries leaked. It even still works afterward like 75% of the time.

If it's battery acid related corrosion, the usual recommendation is to use baking soda, with enough water to make it muddy, and scrub it. That LOOKS like battery acid corrosion, but I have no idea why it would be on a non-electronic toy!

It doesn't need to have been in contact to batteries, but maybe to another metal part. That's storage damage. On the solution, try what TT said.

When TT and Jose agree about toy-related topics, the laws of physics will bend to make sure they are not both wrong

I Agree! Looks like battery acid corrosion, commonly found in trypticons and omega supreme's. I have had several jetfire's with this problem, I do own 12 of them.... The takatoku macross valkyries have the same problem..

My guess is that they used some copper in the chrome coating/metal.
Copper+air+water(moist) -> corrosion (electrical current).

In the "current day" toy's copper is used less to none.. In the good al days it was used a lot.
