If you don't have baby shampoo, just use Dawn dish washing liquid. Just don't keep her in there long. You can make sure she doesn't drink it (don't think she would). You just want something to break up any oils that may be used to bind the product to whatever it was sprayed on. Rinse her well, and rub her dry well, to get everything from between the scales. As good as you can.
I would do that asap, incl. the cage makeover and clean up. A good soap and scrub should do it, follow with a clear water rinse. You don't need to sanitize anything, but you need to get any possible residue off, that may have been transferred from the snake to the cage/hides/dish/substrate.
