Substitute for methylene chloride



I received the following e-mail from one of our Air Quality inspectors. 
The facility needs a replacement that would meet FDA's stringent
requirements.  Any ideas?  See request below...

An inocular silicon lens manufacturer (contact lenses, eye glasses,
etc.)asked if there is a substitute to Methylene Chloride use for their
HSD that meets FDA requirements.  They use Meth Chloride in their
California plant.  I told him that you would get back with him and the
success (hopefully) that you've had or will have with Fl Metal steering
away from Trichlor.  But the kicker is meeting FDA requirements.  They
use Meth Chloride for the inocular silicon lenses.  FDA is stringet on
the use of Meth Chloride due to the silicon implant problems.  Have you
read about substitutes for Meth Chloride.
