cleaning a horsehair brush

[Coopers ST]

Hey all,
Like the title says, how do you clean a horsehair brush? I just ordered one and thinking ahead. I am guessing I will have leather cleaner on the seat, agitate it and 'scrub' it in with the brush, then wipe off with a MF towel. Now my brush will have cleaner on it, do you just rinse it off, use soap, or...

Thanks

Just rinse it with water - that's all you need to do.
