^^^ Ditto, but if you have wooden handled brushes than try not to get the handles too wet. I fill my bathtub with a couple inches of water, and place the brushes brush-side down, along with some bleach and Listerine. After a while of soaking I rinse and scrub them, and then put them in front of a fan brush-side up to dry.
To keep the main dirt and dust off for a longer amount of time I just scrape them against the stall bars every now and then every time I groom.
