Does is clear up??
Sometimes I get milky DCM from distilling. But in the end, it turns clear, with water dropplets on top.
Dcm are water are sometimes hard to separate, it takes a while, so maybe if you let it stand, both layers will form.
Remember that when doing a water wash on a Dcm layer, to get all the Dcm out you have to be patient as it takes a lot of time to separate when compared for example to xylene.
