Remember, though, a thorough hand washing for at least 20 seconds with soap and water is still recommended. This is to carry in your car, or to use if you just can't wash at a sink.
Big thanks to Katie Herzog at The Stranger for this recipe:
2/3 cup 99% isopropyl or rubbing alcohol (or you can substitute some high proof drinking alcohol like vodka or Everclear but it'll cost you more)
1/3 cup aloe vera gel
10 drops of essentials oils like lavender or tea tree (optional)
Mix it all together
That's it. You're done.
