Keep an eye on it. So long as it isn't constricting her tail it won't be too much of a problem.....at the moment. If all is well in this respect, what I can suggest is that just let her settle. Too much bathing with no result isn't helping. If you can't get it off after a really good soaking - as suggested above - then it probably no point continually stressing, or stressing her.
The next time she comes into shed, as soon as you notice her eyes are blue, start misting her everyday. Make sure her warm spot is at a nice top temperature to prevent cold chill and at the cool end have nice tight hide so that when she moves from her warm end to cool end, she can coil up nice and tight which helps maintain body warmth for longer. By misting her everyday, come shed time she should be able to shed much better and the old tail skin will come off with the newly shed skin. Or, even if you need to assist her, it should be a much easier process.
When you spray her, make sure the water is warm. She may jump when she first feels the water hit her but quite often they will settle down again. My olives use to jump at the first spray but then they'd just stay put, seeming to enjoy the misting.
