Does anyone know if there's a product that removes the oxidized layer from copper? Being able to put the HS in a bath of the stuff would be best. I'd rather not use any kind of brush or cloth, because the spaces inside my Millennium Glaciator are VERY small.

Once the oxidation is removed, can I spray the HS(except the bottom area that contacts the CPU) with some kind of protective coating---to keep air away from the copper's surface?

Thanks a lot for your suggestions!

"Keep air away", THAT IS EXACTLY WHAT YOU DO NOT WANT TO DO. Never, ever, ever put any coating/paint on your HS it will greatly decrease its performance.

I don't know about a diping solution for oxidation, but I know that ketchup can be used to cleen copper, the chemicals in it (mainly viniger) polish coper, you have to apply it, let it sit for a minute and than wipe it off.

Vinegar should work to remove the discoloration. But be sure to wash the block throughly (3x) with water after you wipe it down with vinegar. Why not just use steel wool?

Don't know what to coat it with, copper is notorious for oxidizing underneath any paint or sealant. Maybe a thin layer of silicone grease? Or, cut some silicone RTV with acetone and dip the block in and let it dry, should give you a thin layer of RTV that might work....

How about anodized waterblocks? Do anodized waterblocks suffer from any kind of performance decrease? Even if there was a slight loss in performance, I think it would be well worth it to cut off the entire corrosion in the waterblock issue :)

annodized will probably decrease performance. If you access to some chemicals, HCl or Muriatic acid should do the trick, and it doesn't eat copper. If that does not work, I am sure that some Dilute Nitric Acid will do the trick. As far as keeping it from happening again, the only thing to do is to keep it away from anything with oxygen in it, which should be fun to find.

Why don't you take it to a plating shop. Have them clean it and gold plate it, of course you'll have to remove the fan first right ?

That's an excellent suggestion, LimeyGreg. Anyone have any experience with gold-plating copper? And yes, the fan would definitely have to be removed for the electro-plating process.

gold plating is actually a good idea, you don't have the best thermel transferance, but Gold is actually a slouch either. And gold doesn't react with air either, good idea.
