My routine is remarkably similar to Pjrage. I hit the alum block, however, between the warm and cold water rinse...probably better his way.

I've used alum as a routine toner like this for about 15 years. It stings a bit and that serves to provide good feedback on how well I've shaved (try for bbs and no sting).

On the rare bad nick....you may have to hold the block against the cut with a little pressure. This will work. With little bleeders, a quick pass of the block will work.

Best.....
