Vacuum grease?

I have a wash bucket for all my glass, some of which I realized still has vacuum grease on it. If I filter before I rotovap would it be cleaned. Would it work with just filter paper, or celite 545 an carbon, or would I need to add another absorbent specifically for that? Or is it all trash?

Depends on which vacuum grease to some extent.

And YUCK!!!

Hexanes should be able to dissolve whatever grease. Is it food grade grease?

I think so. It’s for all my short path joints it’s Dow Corning grease

The problem is its already in my ethanol bucket. So don’t know how to separate it

Vacuum grease that is silicone based should not dissolve in alcohol to any appreciable degree.
