Title: How to clean an Hasselblad H glass components?
Post by: airfang on September 15, 2018, 01:23:28 am

Hi all!

I wonder how do you clean the glasses on your Hassy H system:

- viewfinder bottom glass
- focus screen
- mirror

Thanks in advance!

The viewfinder is cleaned like a lens. The screen and mirror, you do not clean. Use a blower for dust if you must.

Thanks! I got the camera used and saw some fingerprints on the focusing screen... wondering what's the best way to clean it (without sending it to service obviously)

Trying to clean a focusing screen usually leads to frustration. If you must, you can try alcohol and soft wipes of q-tips. The better solution is simply to exchange the screen, they are not that expensive (about 100$ used).

extract, drop it in a distilled water with few drops of glass cleaning solution for a long while, get out, dry with blower.. use plastic tweezers

If you're going to use alcohol make sure it's Isopropyl alcohol. Rubbing alcohol has an oil in solution with it.

Distilled water with tiny amount of ammonia and a lint free tissue also works.
