Some of the problems start from that dust..
You might need some alkaline solution to wipe that dust, since its, most of the times degraded grease/oil, mold and so on.
Usually Ammonia or hydrogen peroxide 3% or activated water pH ~ 10, then ethyl alcohol > 90% does the job.

Thanks George,
Yes, the CZJ is quite dusty but the later Opton 1.5 is in decent shape al arround.

The CZJ also has aperture oil and from f/1.5 tof/2 is a bit stiff but is okay at smaller apertures.
The Opton has mild oil and aperture is smooth but they BOTh need looking after.

What's the best way to deal with the haze on these lenses? The usual lens cleaning fluid helped a tiny bit, but there is still a bunch more.

Usually Ammonia should deal with haze nicely, I kind of don't like the smell and just use electro-activated water ~10pH, since I always have that at hand.
With same success I have used a quarter teaspoon baking soda dissolved in a cup with distilled water, after that I finish with ethyl alcohol > 90% or mixed with distilled water.
You basically need something alkaline to clean the oily traces, it apear as haze but it degraded oil/grease as I wrote above.
Even some baby soaps mixed with distilled water should do the job.
