Does 91% alcohol kill fungus?

Answered by Frank Schwing

91% isopropyl alcohol can be effective in killing foot fungus. Isopropyl alcohol, also known as rubbing alcohol, has antifungal properties that can help eliminate fungal infections. However, it is worth noting that the effectiveness of alcohol in killing fungus may vary depending on the specific type of fungus and the concentration of alcohol used.

Isopropyl alcohol works by denaturing proteins and disrupting the cell membranes of microorganisms, including fungi. This can result in the destruction of fungal cells and the inhibition of their growth. The higher the concentration of alcohol, the quicker it can penetrate the fungal cells and kill them.

However, it is important to understand that using alcohol alone may not completely eradicate foot fungus. Fungal infections, such as athlete’s foot, can be persistent and require a comprehensive treatment approach. This typically involves a combination of antifungal medications, proper foot hygiene, and maintaining a dry environment.

When using isopropyl alcohol to treat foot fungus, it is recommended to clean the affected area thoroughly and then apply the alcohol using a clean cotton ball or swab. Gently dab the alcohol onto the infected areas, making sure to cover the entire surface. Allow the alcohol to air dry before putting on clean socks or shoes. It is essential to repeat this process regularly, at least twice a day, for several weeks or until the infection clears up.

While 91% isopropyl alcohol is generally effective against foot fungus, it is important to note that higher concentrations of alcohol, such as 99%, may not necessarily be more effective. In fact, concentrations above 90% may evaporate too quickly, reducing the contact time needed to kill the fungus. Therefore, it is recommended to use a concentration of around 70% to 90% for optimal results.

In addition to using alcohol, it is crucial to practice good foot hygiene to prevent the recurrence of fungal infections. This includes keeping the feet clean and dry, wearing breathable footwear, changing socks regularly, and avoiding walking barefoot in public areas.

It is also worth mentioning that if the fungal infection persists or worsens despite using alcohol and practicing good hygiene, it is advisable to consult a healthcare professional for a proper diagnosis and appropriate treatment. They may prescribe antifungal medications or suggest alternative treatments based on the severity and type of foot fungus.

While 91% isopropyl alcohol can be effective in killing foot fungus, it should be used as part of a comprehensive treatment approach and in conjunction with other preventive measures to ensure the best possible results.
