So, I read here denatured alcohol can bring tired, oily, oxidised, dead skin filled stings back to life. With 30 or so basses on hand, that sounded good to me, so I ponied up $14 for a gallon, and filled a BAPJ (big a** pickle jar) with it. Pulled some oxidised, tired sounding rounds off one of my G&L L1000's and soaked them overnight; occasionally shaking them up when I passed it on the kitchen counter. Pulled them out 30 or so hours later, placed them on a towel on the counter and let them air dry-which don't take too long. Strung the G&L back up about an hour later; and... Yep, it works like a charm. I've repeated this on several basses now. In fact, I pulled out all my "used but saved in case I break a string on the job" sets of extras, and have been "processing" them as well. The BAPJ did evnetually develope a layer of filth and ick that settled down in the bottom. So, I got a second BAPJ, made a funnel of paper towels, and "filtered" the denatured alcohol; and am continuing to use it as needed. I cleaned one set twice, and the tension/de-tensioning hasn't seemed to effect them. Of course if you beat the tar outta your strings, and the show wear from frets, or say move them from bass to bass so fret wear marks don't line up, or the break point over bdige saddles moves, or where they pass thru the nut moves...you might start getting weird overtones, or have intonation problems. YMMV; but, as far as I'm concerned, it's no longer "urban myth" by me. So, there ya go.
