After much experimentation I've settled on the following routine:
(starting as soon as I put down my razor for the final time)

-Warm water rinse
-Cold water rinse
-Alum block (optional, as I don't always use it)
-Cold water rinse
-Light pat-dry with towel
-Trumpers Coral Skin food (let settle while I clean up)
-After shave of my choice, either a splash or balm depending on my
preference that day

All this, along with a great shave, provides that sticky smooth feeling that is the true payoff of this hobby
