I do a cold water rinse, then use the alum. No need to wet the alum since my face is already wet. I keep a sponge near the sink to clean up so I simply use the sponge to wipe down the excess water on the alum bar and store it in the plastic box it came in. I keep the lid open so it can dry, then close it before I go to work in the morning.
why rinse it off?
