Tarnished Hardware - Resto or Replace?

I've just got all of my guitars out of storage (they were under a bed at my In-laws while we went through a LONNNNNG house move) and i've noticed the hardware on my PRS has tarnished a LOT. The bridge pickup was definitely already on it's way beforehand but now the bridge and neck pickup cover have picked it up too.

Does anyone have any tips on how I can return these to a shine? Is it just mask off and autosol the F**K out of them or are they a lost cause?
