The Power of Alcohol in Killing Germs

As we navigate our daily lives, germs are an ever-present threat to our health. With the rise of COVID-19, it’s more crucial than ever to understand how to effectively kill germs and keep ourselves safe. One of the most popular methods is through the use of alcohol-based sanitizers and cleaners. But do they really work?

How Alcohol Kills Germs

Alcohol molecules target germs through a process called denaturation. This involves bonding with the fat membrane surrounding virus and bacteria cells, breaking it down and ultimately killing the cell. When used in the right concentrations, alcohol can be a powerful tool in the fight against germs.

Understanding Isopropanol and Ethanol

There are two main types of alcohol used in sanitizers and cleaners: isopropanol (rubbing alcohol) and ethanol (drinking alcohol). While both are effective, ethanol is generally stronger than isopropanol. However, they both require the right concentrations to be effective – between 60 and 90 percent, according to the Centers for Disease Control and Prevention (CDC).

Good Ol’ Handwashing is Still Number One

While alcohol-based sanitizers are convenient, good old-fashioned handwashing with soap and water is still the most effective way to kill germs. Soap is more effective at killing germs than alcohol, making it the top choice whenever possible.

Does Alcohol Kill All Germs?

When used in the right concentrations, alcohol can kill a wide range of germs, including viruses like influenza and coronaviruses, bacteria like Salmonella and E. coli, and fungi like Coccidioides immitis. However, it’s not effective against all germs, such as polio and hepatitis A. Additionally, some bacteria and viruses are becoming resistant to alcohol’s disinfecting power.

COVID-19 Prevention

Using hand sanitizer and disinfecting surfaces are crucial in preventing the spread of COVID-19. According to a 2020 study, alcohol can effectively kill the new coronavirus (SARS-CoV-2) when used properly.

Cleaning 101: How to Use Alcohol to Disinfect

To reap the benefits of alcohol’s disinfecting power, choose products with an alcohol content of at least 60 percent. Make sure to follow product instructions, keep products away from kids and pets, and store them safely.

Hand Sanitizer Essentials

When using hand sanitizer, make sure your hands are clean and dry. Apply a dime-sized amount, rub it in thoroughly, and reapply as needed. Remember to check the label for product-specific directions and avoid products contaminated with methanol.

Disinfecting at Home

When disinfecting surfaces, preclean the area with soap and water, wear gloves, and follow product instructions. Make sure to wipe down high-traffic areas regularly, especially if someone in your household is sick.

No Alcohol? No Problem!

If you don’t have access to alcohol-based products, don’t worry! Good old-fashioned handwashing and alternative disinfectants like bleach, hydrogen peroxide, and UV light sanitizers can be effective.

Can I Clean with Booze?

While it may be tempting to use your favorite boozy beverages to clean, they’re not effective in killing germs. Alcoholic drinks contain too little alcohol to be effective, and even if they did, they’re not formulated to stay on surfaces long enough to kill germs.

The Bottom Line

Alcohol-based products with a concentration above 60 percent are an effective way to kill germs on hands and surfaces. When used properly, they can destroy bacteria and viruses, including the new coronavirus that causes COVID-19. Remember to always use them responsibly and safely.
