I just got these today. Being a total n00b, what's the protocol for using these, step by step? The main questions I have are: 1) After massaging in the Proraso Pre Shaving Cream, do I rinse it off before applying the shaving cream? 2) In order to make lather in my bowl, do I just dunk my brush into the TOBS tub, or should I use my finger (or a spoon) to scoop up a chunk? How do you use these?
