I soak mine or immediately wash it the same way I dirtied it. I put my dirty mixing bowl in the sink and fill it with hot water and soap. I vigorously "stir" the water and soap and my whisk comes clean pretty instantly. If I have waited too long, then I soak. This the exact same way I clean attachments on my electric hand mixer, but keep them attached to mixer and use the power of electricity instead of my puny muscles.
