Bio-Brochure from Froglube...
http://www.froglube.com/docs/Product...risonFinal.pdf Says it's food-grade bio-degradeable... I still don't think it'll draw anything OUT more than opening and closing your pores often will.. I think you'll have to wrap your hands in moist heat, or soak in a warm bath in a sink or bucket or something and let the biomechanics do the work for you, but that may be something to help clean up after your hands that won't be caustic.
