I just "inherited" an Echo E 135mm f4.5 enlarging lens, poorly cared for. It has a lot of haze on the front element as far as I can tell by shining a flashlight obliquely through it from behind. I have tried Kodak lens cleaner and denatured alcohol as mentioned in other threads here. I can see no way to remove front and rear elements-the housing appears solid, and no serrated rings or slots for spanners. I think the lens is probably too "cheap" for a professional CLA. Any other haze removing suggestions other than 2000 grit wet-or-dry? Thanks
