Once I found how well a few days soaking in denatured alcohol restores life to strings, I found it a nice way to cut down on buying new ones. I play pressurewounds, have a few sets, take the current one off, soak them, and put another on while they soak. After a few days I hang 'em up and they're back in the rotation.
Yeah, I've used the alcohol soak tube trick for years, to great results--rotate a couple sets just as you described. I get three passes out of a set that way: new, soaked once, soaked a second time.
