Do you mean your rabbit smells of wee & poo? Is she very tame? You can dunk her rear end into warm water and using a pet or baby shampoo, clean her up. Dry thoroughly and make sure she is not sitting, lying in dirty bedding. Most bunnies prefer a clean area but not all. I put a litter tray in the run/cage/house and mine all used it. Line it with a newspaper and then sawdust, chippings, paper shred or hay. When you change it, pick up a few of her carlings and drop them in so she will again associate the clean area with doing business. If you have a wooden cage, get a piece of lino fitted and that can be washed and sterilized. The cleaner you keep her, the cleaner she will keep herself especially in the summer when flies will lay eggs on her rear end if it is all mucky and that can get very serious. Good luck
