Hand Sanitizer

What you'll need:

• 3/4 cup of isopropyl or rubbing alcohol (99 percent)
• 1/4 cup of aloe vera gel (to help keep your hands smooth and to counteract the harshness of alcohol)
• 10 drops of essential oil such as lavender oil or you can use lemon juice instead

Directions:

• Pour all material into a bowl ideally one with a pouring spout like a glass measuring container.
• Mix with a spoon and then beat with a whisk to turn the sanitizer into a gel
• Pour the gel into an empty bottle for easy use, and label it "hand sanitizer."

Tips:

• Make the hand sanitizer in a clean space. Wipe down counter tops with a diluted bleach solution beforehand
• Wash your hands thoroughly before making the hand sanitizer.
• To mix, use a clean spoon and whisk. Wash these items thoroughly before using them.
• Make sure the alcohol used for the hand sanitizer is not diluted
• Mix all the ingredients thoroughly until they are well blended ·
• Do not touch the mixture with your hands until it is ready for use.
