Sure! I like to do these things to maintain clear skin:

1. Clean my phone handset(s) once a week. That thing touches my face all day, every day. Ick!
2. Wash/change my pillowcase weekly. Pillows are the most germ infested place in your room.
3. Clean my makeup brushes once a month. I try to buy liquid stuff in tubes so my fingers don't touch the product all the time.

Hope those help!
