While your waiting, make up some lather with the brush and let it sit for several hours before cleaning it out. That will help tame any funky odors the brush might have.
Nice gear! Darrin here's a couple of threads I'd like to recommend to you. Our weekly Shave Of The Day (SOTD) and August 30 day Focus thread, which will change in September, here is the link for the 30 day focus group. Please join one or both, it's come as you are. Ask as many questions as you have, it's a lot of fun. Hope to see you! Kerry
