Hydrogen Peroxide Travel Spray (3 Pack) - Portable First Aid Solution for Cuts, Scrapes & Disinfection on the Go

I use a mouth guard type of device when I sleep. I use this hydrogen peroxide when I clean it each day by putting a little hydrogen peroxide on the guard in a little glass cup and add some water and let it soak a bit before rinsing it off again before using the guard again the next night. This size is perfect for when I fly to take some with me.
