Hi all,
I just got my Thater in the mail today along with a brush stand and a strop. Unfortunately the soap and razor have not gotten here yet. Anyways I need a shave tonight (cousin's graduation in the morning) plus I'm just extremely anxious to try out my brush.

My question is: Will using a generic Barbasol shaving cream or a perhaps better soap like the Dr. Bronner's soap that I asked about here, ruin my brush?

Like I said I have to shave tonight but I wouldn't want to ruin my brush using a crappy foam, so any advice is greatly appreciated.

Thanks!
