In my local pharmacy, I noticed Compact Interdental brushes from Oral-B; they are excellent for cleaning out my airbrush. They have a very small, pivoting bottle-brush head, come in packs of two, are inexpensive, and reusable. They appear resistant to most thinners and paints; lacquer and enamel thinners have not affected them at all. They may also be useful for cleaning dust out of panel lines.
