Acetone may be the go. I imagine turps would leave a stain and I have never heard of anyone using turps on optics. It sounds pretty harsh and also likely to stain. It may damage the coatings.
Acetone is something you can use. As I recall it was recommended by RCOS to clean their mirrors with - one approach.
I also think it is a good idea to check it out on something else before trying it on your lens which you need to be certain before potentially wrecking your lens sort of thing.
