Re: toenail processing

From:Tara Miller

I used to work for a derm lab and we would soak the toenails in "Neet" of 
"Nair". Both of these are great for softening up the thick layers of 
keratin. Just place the fixed and unprocessed nail in the middle of some of 
the cream, let sit overnight, rinse well and then process as usual. This 
really helps with cutting these nasty things.

P.S. If the toenail is already processed and embedded, you can also let the 
surfaced block soak for a few hours. Rinse well before cutting.
