Only people with a spare hour or two should start hunting around on this 
topic. Yep, I just did.

After reading several pages and discovering that people actually use 
electrolysis to produce hydrogen which they then add to the input air 
stream to their cars, I found this page

Look for hexa.

Not much evidence but what there is appears to suggest that at voltages 
we use there is no problem.

Personally I use baby oil and fine abrasives on hard blocks for most 
things, but do occasionally use the electrolysis tank. Don't use acids, 
even mild acids. Not sure why, just never have.
