Late to the thread, as usual
I use silicone brushes for some stuff, ordinary bristle brushes, for other stuff and extraordinary Italian Black Boar Bristle brushes for the best stuff. I put the first two in the dishwasher, bristles facing downward. I clean the boar brushes they way I was taught to clean artists' brushes
1. Gently knock out what's in the brush by rapping the side of the brush against a firm surface like the edge of a trash can or something that won't dent the ferrule.
2. Rinse the brush with bristles facing down in warm water (or warm oil for chocolate).
3. Put some liquid dish detergent with or without peroxide in the palm of your hand and gently swirl the bristles in the soap to shampoo them.
4. Repeat steps 2 and 3 a couple of times, knocking out the residue as described in step one until you're satisfied that the brush is clean.
5. Very important finish: make sure to hang brush with bristles facing down to dry. AND KEEP BONE-HEAD SAVORY FOOD COOKS AWAY FROM YOUR GOOD BRUSHES!
