Paul, when I first read your post I thought "Huff and puff and blow them off", then thought - metal filings?? maybe not - might scratch as they fly across the surface? I think you need to try and tip what you can off - not sure with an LB - can you get the mirror up to vertical without dropping it!! Then, with care (and the mirror vertical in case you drop what you are holding!), wave a magnet over the surface and see if you pick them off - but may well not be magnetizable filings? Then off to the blower and then to a soft brush or maybe straight to a liquid wash as per manufacturer's instructions. I hope that you don't have to go that far. Now, remember these are suggestions from someone who hasn't cleaned a mirror yet!
