I have 3 shaving brushes, and, honestly, I like them all.

I use the soft badger brushes for creams, and the stiff boar bristle for soaps.

My question is about preparing my selected brush to shave, because I am reading posts that mention soaking the brush before use.

My normal process has been to pick the brush according to the lather medium, run it under hot water for a second or two, give it a quick shake, dip it in the stuff, transfer to the bowl, and start whipping up lather.

What would I be trying to accomplish by soaking my brush for several minutes versus just wetting it under the spigot for a few seconds?
