clean the equipment in a cold immersion tank or by hand depending on the
size of the part to be cleaned.  They are desiring minimal change to the
process, but a substitute for MEK.  I tried SAGE, but unfortunately, the
high ranked items on the reults list will not work to remove his solvent
inks (e.g. surfactants).  the materials that need cleaning are
predominantly stainless steel.  The facility also would like to avoid
carcinogens.

Reducing Solvent Use In Screen Reclamation. United States Environmental
Protection Agency, Design for the Environment (EPA 744-F-96-011),
