Purell Advanced Hand Sanitizer Refreshing Gel This buy isn't directly related to fresh breath, but if I'm out and about, it's key that I clean my hands with Purell Advanced Hand Sanitizer Refreshing Gel ($9 for a pack of three) before touching my mouth to use floss or eat a mint — having the travel-size containers on hand are a must.
