I agree with everything said here, rats do not spontaneously get better from horrible symptoms like that, and we know that the longer you leave these things, the worse it gets, unfortunately you blithely ignored the "get to the vet" advice and instead bathed her even more, actually damaging her skin. Your posts on here and your actions are all we have to go on. Its all well and good that NOW you say you would've taken her to the vet, but you didn't. Next time the whole forum shrieks "take her to the vet" run, don't walk to your vet...next rat might be saved.
We often learn the hard way, but we admit it and learn. You are denying everything.
RIP Star, if you were mine, you would've been treated, and if you were too sick, I would've let you go and not let you suffer any longer.
