A little update:
I soaked her for an hour in warm water yesterday and today, both times with rough terry cloth towels in the tub so she could slither around in them (although basically she just sat on top of them). Yesterday, I scrubbed her with the towels; today, I kinda rubbed her while wearing rough latex gloves from Home Depot. Most of the shed is gone, including the eyecaps and the tail tip. Now there's just a stubborn 3-inch patch on her back. I tried pulling it off, but she is just losing patience with me and getting really pissed off.
Does anyone have any other suggestions?
Is this a common problem with BPs?! Cuz I'm getting fed up with this. If I didn't have the week off from work, I would've given up a long time ago and given her back to the pet store where I got her.
I should just stick with corn snakes.
