What is B&A Spray?

  • Turn Off-The-Shelf Grain Alcohol into a Powerful, Non-Toxic Disinfectant
  • Prevent the Spreading of Disease from the Surface of Masks or Other PPE
  • Take Your Spray on-the-go to Protect Yourself in Crowded Spaces

Why Spray My Mask?

  • As we use our mask in our normal lives, the external surfaces are exposed to airborne microbes, which could contain COVID-19
  • Just as we social distance, it is our responsibility to eliminate any potential vectors for viruses to spread including our masks

Practical and Safe Cleaning for Face Masks

The CDC recommends wearing a mask to reduce the transmission of COVID-19 and other infectious diseases, but their advice can be difficult to follow in the real world.

Examples from their webpage:

  • Wash your cloth mask whenever it gets dirty or at least daily.
  • If you have a disposable face mask, throw it away after waring it once.
  • Don’t touch the mask, and, if you do, wash your hands or use hand sanitizer.

For safety, we need a better method, and that’s where a non-toxic, sanitizing mask spray is useful.

Historically, the safest and most effective disinfectant is ethyl alcohol (ethanol, grain alcohol, C2H50H). Ethyl alcohol quickly kills microorganisms like bacteria, fungi, and viruses by dissolving their membrane lipid bilayer and denaturing their proteins. However, ethyl alcohol is safe to consume in moderation, and billions of people do so every day. Ethyl alcohol is currently used as an anti-microbial preservative in more than 700 liquid medicines. It is the active ingredient in some products on the EPA’s “List N” of COVID-19 disinfectants. Furthermore, ethyl alcohol is shelf-stable and does not break down over time. For a sanitizing mask spray, ethyl alcohol is ideal.

For those of legal age, ethyl alcohol is available as “grain alcohol” wherever liquor is sold. It comes with brand names such as Golden Grain, Crystal Clear, and most famously, Everclear. However, whether you buy a branded or generic product, you’re getting the same thing: a mixture of ethyl alcohol and water. The proportion is indicated by a percentage or proof, and you want at least 140 proof (70 %) alcohol. NOTE: Only ethyl alcohol is safe, so only use a product sold at a liquor store.

To use ethyl alcohol as a mask spray, just fill a spray bottle and spray your mask before and after you anticipate potential contact with COVID-19. It’s most convenient to spray the mask when you’re not wearing it, but inhaling a small amount of ethyl alcohol is not harmful if done infrequently. Avoid inhaling ethyl alcohol vapors frequently — doing so adds alcohol to your bloodstream similarly to but faster than drinking alcohol. However, it would be difficult to become intoxicated by inhalation because of the quantity ingested. Cloth and disposable masks we’ve tested are not harmed by spraying, and spraying the mask throughout the day is a practical method of keeping it safe to use until you can wash or replace it.

To hinder potential poisoning by young children or mischief by older children, you can add a denaturing solution to your ethyl alcohol which makes the alcohol extremely bitter, unpalatable, and unsuitable for drinking. During COVID-19, the FDA has issued guidance for denaturing alcohol in this manner. The resulting denatured alcohol still works well as a mask spray, even if vapors are inhaled. Denaturing can also reduce the social stigma or legal prohibitions that might accompany carrying ethyl alcohol on your person and in a vehicle. To use our denaturing solution, add drops according to the bottle size you purchase according to the table below. And, re-label the bottle!
