(Mod: I hope I am in the right place. If not, please relocate me. ) I've done some gigs and rehearsals recently where the heat and the humidity in the atmosphere (not to mention 2 Smoke Machines and Stage Lights ) have reduced my strings to feeling like sticky washing lines. I remember seeing The Hamsters a few years ago (UK based long running Blues/Rock trio) at some particularly "sweaty" gigs and Slim the guitarist was using WD40 after every song and absolutely drenching his strings and fingerboard in it. I remember thinking this was possibly a bit questionable as the can does advise you to use it only in "well ventilated" spaces as I think there may be one or two toxic elements in it. I wondered whether any of you guys have any experience of using this product, or anything else, to keep your strings "playable" during a gig. Maybe by spraying the WD40 onto a cloth and then wiping the strings with it? Are there any drawbacks/dangers with using it? I already use FastFret before the show but, by half a song in, it's as if I hadn't bothered. FYI, I'm currently using Rotosound Jazz Flats and the set I have on are only a couple of weeks old (brand new in my terms ) Any advice would be much appreciated.
