Let's face it people bass strings are very expensive. Now, I realize that when you play on a set of strings for a while you are going to deform them somewhat. Especially over the frets, creating flattened areas that don't allow the string to vibrate as freely as a new set, making your strings sound dull. There is no getting around that. However the other leading cause of dead strings seems to be oil and dead skin dirt and what ever else clogging the windings. Have any of you found an effective way of bringing your strings back to life? I've boiled my strings in water and also vinegar. The vinegar had better results. I've also tried soaking strings in denatured alcohol, but nothing seems to do an exceptional job. Opinions?
