Thoughts?

Take the batteries to the guy who shines your shoes...

Unfortunately, I usually shine my own shoes. In a pinch I'll let the butchers at the airport have a whack, but this is a rare occurance.

try 0000 steel wool. Tape some around a dowel to get it down where my fat fingers can't work it.

Use an eraser or rubbing alcohol on a Q-tip

An eraser to clean them first, then a very light coat of Boeshield -

I always used it on camera contacts and the hotshoes - Boeshield will prevent oxidation and maintain the conductivity - if they're corroded you might also try Rust Free first which is also a product of theirs - you can find 'em both at WoodCraft if there's one near you -

I'll look up that stuff up. They are caked on pretty badly, so I guess corrosion might be more appropriate than just oxidized.

mix one part vinegar with one part lavender oil and simmer for 8 hours. Mix 3 parts corn meal to one part baking soda and let sit for 4 weeks. Mix and feed to a chinchilla. Take chinchilla feces and spread on contacts using carrot sticks dressed with hemp fiber.

No prob, Spence - stuff like this is what old guys do with their time...

Boeshield was developed by Boeing for the aircraft industry - they used to have pretty detailed info on their site, I used it on my Hasselblads, so obviously I trusted it -

Woodcraft had it on sale as a 3-pak for $22 or so - which is cheap - spray bottle of Rust Free, large spray can of Boeshield and another product for getting pitch off blades, etc - excellent price, used to pay almost that much for a smaller can of Boeshield alone.

Spray the Rust Free on wait a couple minutes and use a green 3M scrubby if it's that corroded -

BTW - it works great on saltwater stuff - but I'd be careful with Rust Free on any painted surface - just used it on my 8" Shimano needlenose pliers and it did an excellent job, then coated them with the Boeshield for corrosion protection -
