Mamiya RB/RZ Lens Optic Cleaning

Hi,
I'm interested to hear suggestions for cleaning dust and haze from two lenses:
Sekor Z 37mm and a Sekor C 50mm

Anyone have really good experiences from a repair shop?
Thanks!

A very wide-angle lens and a full-frame fisheye.

So how much dust is there, and where is it. Same thing about the haze, and how do you define "haze"?

How did they get this dust and haze, if you know, and have you tried to do anything about it yet?

Howdy neighbor. I'd contact Bill Rogers. He's a member here, and he specializes in Mamiya's.
