I soak my brush in hot water mainly to get the brush as hot as possible so the lather stays warm.
Why soak the brush?
If you haven't tried it then trying is the best way to answer your question. Clearly not all see a benefit and not all do not see a benefit -- otherwise either everyone would soak or no one would soak (i.e. YMMV). You need to rely on first hand experience to determine if there is one for you regardless of how many opinions you read.I just swish my badger brush in the water as the sink is filling up. This probably takes about 30 seconds. Then I face lather. I do not SOAK my brush. I have never understood what benefit there is supposed to be to soaking a shaving brush for longer.

I find that my badger seems to work better when soaked versus dipped. Again, YMMV.
If everyone did that, we'd only have about 5 threads here at B&B.
