I got my first simpson brush today from West Coast Shaving. It is a Duke 3 in best - it's a thing of beauty. I have a few questions about caring for it since It was a good chunk of change and I would like it to last. I am in the process of removing some of the smell from it. Dawn dishsoap lathered it, Vinegar and Water soak, Ice water soak and now it is sitting in some Proraso lather I whipped up with it. I plan to vinegar water soak it and then finally shampoo/conditioner. My real question comes to how much downward pressure should I be using when making lather with it? I have not used much at all and it seems to be taking a while. I notice that on GeoFatBoy's and Mantic's youtube video that they actually use a decent bit of pressure (Enough to cause the badger to fan out). Is this the correct way to do it, or will it cause a hole to form in the center?
