I had to clean the matte surface of a focusing screen.

Liquid cleaners don't work because they leave deposits in the matte surface.

Anyway I found a neat way to do it using a vacuum bagging sealant mastic tape called AT-200Y Sealant Tape.

It's a chewing gum type of material.

I just used it pretty much like one of those cloths pet hair removing rollers.

The dirt stuck to the tape and left the focusing screen cleaner. I repeated it quite a few times. When I was done it was clean and visibly brighter and contrasty.

I can send you a few inches of tape if you need it.

They normally sell it in big rolls and the closest place around here that has it is fiberglass Hawaii in Ventura.

Thanks Fred, but if this stuff works we have enough cameras to require a full roll.  The 680, RZ and the old 501's all can use it I am sure.

Thanks!  Good to know.

Maybe the sticky material off the clothing rollers could be removed and used in a pinch.

This is one of the methods we use on matte surfaces when cleaning film cameras.

Not a good idea as the 'sticky material' is glue based and will leave a residue.

I can't seem to locate this tape near me without having to order a large roll online. Is there another material that you can get in smaller quantities that does the job? Like a putty or something?

Or maybe that "clay" they use when detailing cars?

I'm going to consider this. I have an FE that really needs cleaning bad.

That clay for cars is a fine abrassive... don't use it.

Send me you address and I'll pop a few inches of the AT-200Y Sealant Tape in the mail for you. I have a big roll left over from a carbon fiber surfboard project.
