Chemical resistance charts are available on the web and from safety outfits.

Here is a listing from ProMinent (Trademark) for Methelene Chloride 
CH2CL2 100% conc.

no resistance to Acrylic,PVC,Polyethlene,EPDM.
Limited resistance to 316 SS, Polyproplyene,PVDF
Good resistance to Viton,Teflon.

If it has limited resistance to 316 Stainless Steel , you might want to 
think about it when you soak it in things you don't want it to dissolve.
