@mdarnton: Thank you. I was not planning to disassemble the front assembly completely, as the fog is in the internal surfaces. However, the assembly is not designed in a way that invites opening: difficult to find a grip.

I must not be like mine or the one in the photo, then, because on ours there's quite a bit to hold onto, though it's not provided with tread. You might find wrapping a couple of rubber bands around the back gives you a better grip, if something is frozen?
As we all know, a picture is worth a thousand words
this is the front assembly from the rear

This is the lens

The middle element Will screw off, the giveaway Is the knurling on the edges in your top foto. There are different techniques to grip the knurled edge and if its stuck. Some may wince, but i find slip-jaw pliers with rubber in the jaws work well to get a good grip, while the rubber prevents damaging the brass.
Second the comment about avoiding too much solution. I use diluted windex in water, then water, but always spray fluid onto fresh lint free tissue before applying to the lens. Dont squirt fluid on the lens directly
I will try. Thanks a lot.
