What's the best way to clean the focusing screen?

[caliber_60]

Should I clean the Hasselblad focusing screen the same way I clean

the lens?

 

Thanks,

I'm not a Hasselblad owner but my advice is don't. You can lightly brush or blow off dust but there the screens are normally made of a different material to the glass lens and not as hard-waring - same goes for the mirror.

Once upon a time, I cleaned the focusing screen on my 35mm and put more trash onto it than I had hoped to take off; about $110 later, it was clean. Check with Hasselblad, check with your local camera dealer, but don't do it until you know.

compressed air, lightly brush, possibly lightly with a lens pen, but no more. Older 500c's can push lens out of adjustment, newer models have softer material in the screen and can be scratched with whatever you are trying to remove. I can recommend the compressed CO2 as well, more pressure, no residue, and portable in the little cannisters you can through in the camera bag.

Good luck, <R>

If you are very very very carefull, soak a cotton swab in dishwashing soap, mildly warm and gently, and I mean very gently, run it across the screen, I have all beatti interscreens for all my cameras and they recomend this method. On the other hand, the first time I tried it I messed up my 4x5 screen. So for my money, I think just getting an air blower will do you better.

Go to an art supply store and buy a very soft, high quality

watercolor brush often called a "mop". Gently use the mop with

baby shampoo and water to clean the screen. Gently blow dry

with air, but not a heavy burst of air. Do not clean a screen like

you would a lens. The surface of most high brightness screens

have microscopic prisms or fresnel rings all over that can be

damaged by rubbing with any kind of cloth. Doesn't matter which

kind of cloth.
