If you're trying to clean a space that's too tight for even a cotton swab, the toothpick can be a help. Just cut a square of facial tissue or paper towel and wrap it tightly around the toothpick, leaving about half an inch (7-8 mm) past the tip. Then you're ready to clean! The Classic shown is the one I received from Aloha (thank you again!), and it was pretty clean, but hopefully you get the idea.
