I've been doing this since reading some threads about 6 months ago about using alcohol wipes on strings. I first tried it with some TI Super Alloy's. I liked the strings right out of the package because they already sounded broken in, but the combination of TI's and alcohol didn't make them last any longer than the EB slinky's I was using on my other bass. My EB slinky's haven't been lasting all that long either wiping with alcohol. I've recently discovered D'addario XL's that I like alot and will see how long they last. I'd like to get 2 or 3 months out of a set if I can. Anyway, since I'm not really noticing a huge improvement in stringlife by wiping with alcohol, I was just curious if I should keep doing this or not? By any chance is the alcohol removing a protective coating on the stings or something?
