Do NOT use isopropyl (rubbing) alcohol. It has a large percentage of water in it. Use denatured alcohol (you'll need to get it at a hardware store). Most denatured alcohols are denatured with a small amount of acetone. Both the acetone and alcohol are extremely volatile and completely evaporate from the strings quickly.
If you boil your strings in water, you have to remember that water will rust steel strings. Stainless strings, no problem of course.
Agreed. Some of us are just gear geeks about everything.
