Hiya,
Im sure u will get lots of varying advice on this one, an i am not about to ram my own down your throat, however, i will tell you what i would do if it was MY dog.
Any dog that is growling is doing so for a reason. Tempting though it can be to think that the dog is being bloody minded, this is not the case. A growl is clearly a dogs way of saying 'back off, i am not comfortable with this situation'.
If you where to push this growly dog, my guess would be that she would rapidly turn to her other options, these are run away, freeze, and bite. If the dog is one who will freeze, u might be ok.
If not, and it runs away, or it bites you, that relationship you are trying to form is going to be seriously set back.
The chances are, if she does bite you, no matter how strong you think you are, it will be a big shock, and you will in all likely hood back off from her. This has happened to me, with a dog i knew very very well, and it was very scary.
If that happens and you back off from her, avoid pushing her, she will know she has a very useful tool to make you leave her alone. Then, you will have an incredibly difficult job getting her to trust you, and face up to her fears.
So, leave her alone for now, dont bath her, just put up with the smell, and work on getting her to trust you. Play lots of games, lots of training, but dont go mad, give her time to settle in. Try not to make exceptions, but also try not to confront her.
If you get into a physical battle with her, it will be a long time before she forgets it, and if she bites you the chances are, she will win.
At the end of the day, what do you want more, a happy trusting friend with a bit of a pong, or a clean and shiny dog that bites you?
