I have taken the front element off an Elmo 1.0 lens for the purpose of cleaning. Although I have used a lens cleaning solution recommended for optical lens there is still a slight milkyness to the surface.

Can anyone advise on a suitable cleaner or method of cleaning that will improve on this result?

Thanks

Tony

I had the same problem with cleaning the objective of a Nikon camera. I could remove the milkyness lining of the liquid by breathing on the lens and use of a micro fiber cloth

Domestos didn’t work then? You could try Mr Muscle, with the benefit that you get a nice lemon fragrance coming from the lens during projection [Big Grin]

I will ask for you tomorrow from my local photographer. [Wink]

Lens pen! It uses black powder on a chamois. They have a mini pro that is perfect for projector lenses. I see them in eBay for $5. You can check their site at: Lenspen Site

As promised Tony I have had a word with my local photography shop on this matter and they say. "The fungus that causes this problem feeds on the lens coating and if gone to far the lens will never clean up, as what you see is the damage done to the coating" but this can be cleaned and recoated. “Apparently”

Hello

Certainly what Chris says ties in exactly with what I have been quoted for to have my lens sorted out. The lens needs to be proffessionally polished to remove all trace of the original coating and then re-coated to return it to its original optical character, apparently a lack of coating makes the lens surface more reflective and hence less light finds its way through to the screen.

Hi Trevor,

Hope your sickness has passed! You will be pleased to know that I solved the problem with Jif bathroom cleaner- a Brillo pad was not needed.

I have discovered that the new soft focus quality of the lens really suits the older more scratched films- the running lines have disappeared [Wink]

Thanks for the advice everyone. Lens is back together and running well. [Smile]
