Don't get the wood soaked, otherwise it might crack during drying. Hold the brush at an angle under running warm water. Put a dollop of shampoo on top of the wet bristles and run your fingers through the bristles for a minute or so and produce a good lather. Then rinse under running water until all the water runs clear. You'll be amazed how much muck will rinse out. Then dry with the bristles down (to prevent all the water sitting in the wood).
