Similar thing happened to my chain as I soaked a used chain in OMS (Odorless Mineral Spirits) overnight. When I soaked a brand new Ultegra chain a couple of months ago to get it prepped for the Silca wax treatment, the overnight OMS soak didn't corrode the chain. The difference, as I can tell:
- last night's OMS was recycled (it was previously used to clean the brand new Ultegra chain)
- I had put the old chain in a couple of ultrasonic cycles in Simple Green and then sprayed the chain off in water
- I didn't completely dry the chain before putting it in the OMS bath
