Miltec is great stuff. After I retired I even sent my son some while he was in Iraq (it was scarce at the time).
I have been using a product called Gunzilla that works great. I've read of quite a few people that prefer it over Miltec.
Gunzilla like Miltec doesn't leave a greasy film but lubricates very well.
Might be worth a try.

EDIT: I forgot to mention that it's a cleaner as well as a lubricant.
