Use your old guitar strings, ask your friend for his/hers, or go to your local music store if they re-string guitars and ask them to save you the old strings. You can also use the ends they cut off of the new strings when they put them on, (which is again good recycling). :) Another thing you can do is use the "ball" ends from the ends of the strings as accent beads, which adds an extra recycling touch. So reduce, reuse, and recycle by making jewelry out of something usually headed for the landfill!
Step 1: Clean your guitar strings!

Alternatively, I would use a scouring powder that can be used on brass and copper. (I did read you can place them in coke overnight, and that will clean them, but I haven't tried that.) I used a scouring powder on mine, and it worked fine.
