Recipes to Make 70% Alcohol Solution for Disinfecting Spray

The CDC recommends alcohol solutions of at least 70% alcohol (ethyl alcohol or isopropyl alcohol) for effective surface disinfection.  See the CDC's complete recommendation here including their list of FDA approved disinfectant brands.  We recommend diluting your surface disinfectant to a minimum ABV of 80%, see our recommended recipes below.

Customers seeking to maximize the alcohol solution they can create with the starting alcohol they have on hand may follow the recipes below to make an alcohol solution that is exactly 70% alcohol by volume.  Diluting below the recommended concentration of 70% ABV may result in the spreading of germs, please take extra care to measure ingredients when diluting to 70% alcohol.
