Hi all. Nitpicky question—I recently received an autograph through the mail, and I noticed there’s a fair amount of dust on the photo (including on parts of the signature). What’s the best way to go about dusting it without running the risk of scratching the ink? Microfiber cloth? Compressed air duster? I’m about to frame it, but I’d like it to be as clean as possible, especially for preservation purposes. Any thoughts appreciated!
