So, my Rivendell was put in "covered storage" over the winter, which turned out to be basically "stored outdoors under a very small overhang near an area that was heavily salted in the winter" - the chain and pedals (and some other parts) are now quite rusty. The chain was an almost new silver SRAM PC 890, but is now completely covered in rust - although it still flexes just fine. The pedals are cheap Shimano SPDs.

Can I salvage the chain by cleaning it, or is it trash? I assume the pedals will be OK with a scrub and some lubricant.
