I have the usual few bits of dust on my focus screen and wondered if anyone has ever tried cleaning a focus screen with one of those vibrating water baths that jewellers use to clean gold and diamonds etc. I was deciding whether to put distilled water into the machine I have, which shouldn't leave any streaks on the screen. My plan was to take out my focus screen and while wearing surgical gloves hold it just above the bottom of the machine for a few seconds to see if it eliminates the accumulated dust and dirt. I thought I would try asking here to see if anyone has ever used this method. Anyway thanks in advance for any advice on this matter.
Hi all
Thanks to all who answered my query. I found an old focus screen from my pentax K30 camera and me being me I though I would give it a try. I put on rubber gloves put distilled water into my sonic bath and held the screen just above the bottom of the bath. I gave it a couple of minutes and too it out. I then gave it a good shake and as distilled water doesn't leave a residue unlike plain water. I let it dry naturally and tried it the following day and the bath had removed all of the dust and left a clean dust free screen which I put back into my camera. It worked perfectly. I don't suggest that everyone tries it but if you have an old screen that you no longer use and a sonic bath then it might be the way forward, it's certainly cheaper than buying a new one. I would stress however that maybe I was just lucky and I certainly would not advise it on a screen that you currently use, but if you have a dirty one that you will never use and your keeping it buried in the back of a drawer it might be worth a shot.
