I did mine with PCB etchant solution from Maplins (radio Shack in the US do something similar). I wiped it on with a cloth then wiped it off again almost immediately. A wipe over with metal polish sorted out any uneven spots.

Ive shared some thing ido....Hey guys,
Does anybody know any simple, safe ways to age or relic new nickel covered humbuckers a bit? I'm not really sure if it's a good idea. What would you suggest? Sand paper? micro mesh pads? lemon juice ?
Yes, I've heard that muratic acid is often used in the methamphetamine manufacturing process. Some crazy shit!Yeah cause there is nothing like muriatic acid fumes, which by the way turns into Hydriodic gas from contact with certain metals. By the way these fumes are on the hit list for the DEA as part of there illicit chemicals list, so beware the big truck outside your house. You think I am kidding about this, I am dead serious. Okay and by the way this gas corrodes everything metal.
