Toothpicks of course are useful but I don't think they hold up to a 4-6 inch metal poker that can reach down stems etc. Also they get dirty and are hard to clean, they're sharp on both ends so you gotta be careful, and they get damaged on the ends.

Pipe cleaners are good for full on cleaning and if you're willing to throw them out (can't really be cleaned easily), sometimes you just need something to unclog your bowl reliably.
