Yield: 12 fl oz of 70% Alcohol Solution

Important Heads up! If you dilute too much you will spread germs not kill them.  For this recipe, diluting too much = diluting any at all!  When in doubt toss it out. Read more: How to tell the ABV of your starting alcohol (isopropyl or ethanol).

Ingredients:

• 12 fl oz, of 70% Isopropyl Alcohol.
• No tap water. Seriously, zero.

Step 1 - In a clean spray bottle, pour the 70% isopropyl alcohol into the bottle.  This solution is already at the recommended minimum ABV of 70%, diluting further with water or other non-alcohol components (like fragrance) may dilute the concentration to levels below what is known to effectively kill germs and viruses.

Step 2 - Store the isopropyl alcohol in accordance with the label directions. 70% Isopropyl alcohol does not expires, contents will kill germs and viruses so long as the ABV remains above 70%.  Source.
