Corrosion on 1321 IEM's

We just opened two sets of 1321 IEM’s from our stock (don’t know when they were originally purchased), and found corrosion on the PC boards of all four devices. The lot number on all four devices is the same: 3122AA It looks as if the flux had not been properly cleaned after wave soldering, leading to corrosion of the components.

The IEM’s from other lots are fine, so were not out of business, but is there a way to get replacements?
