Another alternative is to use Diphoterine(R), an amphoteric, polyvalent, 
slightly hypertonic, non-irritant, non-wsensitizing, non-toxic, sterile, 
ACTIVE skin decontamination solution whose reactions with both acids and 
bases do not generate any significant exothermic heat releases.  It has been 
successfully used in European workplaces and laboratories for a number of 
years, and is effective againts acids, bases, oxidizers, reducing agents, 
solvents, irritants, etc.

More information is available on the manufacturer's website: 
(click on the British flag for the English version) which also contains 
numerous peer-reviewed publications and major Congress Abstracts regtarding 
this product.
