|Sally Beauty sells disposable mascara wands, for cosmeticians to use a fresh wand on each customer. You can buy 12 of them for less than $5, and they'll last a very long time. They're like a little bristly pipe cleaner on a stick, and they really grab the lint and crud. It is nice to have several, as while you're working ultimately they get clogged and you need to work to clean them out. Usually you're in a hurry to sew. At leasure, clean out the remaining crud on the brushes and you're ready for next time.
While you're at Sally's, they have all kinds of little squeeze bottles with long pointy nozzles. They are great as free, nontoxic "canned air" for a final dusting after you've gotten all the visible lint out.
