<p>What I am about to say/share might not sound like "how to clean my focus screen?", but it worked for me.<br> First, let me state that I am referring to equipment I bought new and was squeaky clean inside.<br> Rules:<br> 1: the day you receive your camera, put a lens on it an NEVER removed it in a dusty environment.<br> 2. if you MUST shoot in a dusty environment, like Living History Farms Des Moines, Iowa being hauled about on a wagon over dusty dirt roads and you must change lenses, bring a air-tight changing bag and change the lens inside this bag AFTER you get off the wagon and inside a reasonably clean environment, like the frontier cabin.<br> 3. never removed your lens, if the exteror of your camera is dirty. clean this first.<br> 4. if your screen does become cluttered, only use air to remove to remove the particles. If they cannot be removed with air, learn to live with the dirt, or have a photo repair shop replace your screen and more diligently observe rules "1", "2", and "3" above.<br> IF YOU RECEIVE DIRTY EQUIPMENT, use air only. If this does not work, then have a shop replace the screen and above rules 1-3 above.</p>
