Does Vinegar Disinfect?
The Centers for Disease Control and Prevention (CDC) advises against using vinegar as a disinfectant. Though it may be effective against E. coli and S. Typhi, it is not effective against other bacteria strains such as S. Aureus. ((Centers for Disease Control and Prevention – Guideline for Disinfection and Sterilization in Healthcare Facilities))
Vinegar Can Be Dangerous When Mixed with Other Cleaners
Not only is vinegar not the optimal cleaning solution for disinfection, but it also has many drawbacks when used as a cleaner. For example, because vinegar is all-natural and seemingly harmless, many people don’t realize that it should never be mixed with other cleaning solutions, such as bleach. When vinegar, an acid, is mixed with bleach, it produces chlorine gas, which is toxic. It can cause eye irritation, coughing, and breathing problems. Vinegar should also never be mixed with hydrogen peroxide. Combining these products can create peracetic/peroxyacetic acid, which can be highly corrosive and irritate your eyes, skin, and respiratory tract.

Vinegar Can Do More Harm Than Good
Also, as an acid, vinegar can destroy many household surfaces. For example, the acid in vinegar can etch solid stone countertops such as marble and limestone. It does the same to the sealer applied to solid stone countertops. ((Consumer Reports – Nine Things You Should Never Clean with Vinegar))
Many dishwasher manufacturers also advise against vinegar as a cleaner as it may break down the machine’s rubber components. This goes for the washing machine as well. ((Consumer Reports – Nine Things You Should Never Clean with Vinegar))
Vinegar can also harm hardwood flooring, aluminum, copper, and some stainless steel grades. ((Consumer Reports – Nine Things You Should Never Clean with Vinegar))
What Is the Best Household Disinfectant?
If vinegar isn’t the best solution for disinfecting, what is? The Centers for Disease Control and Prevention advises using a commercial product that has been fully tested for disinfecting properties. The Environmental Protection Agency maintains a detailed list of effective cleaners.
The CDC also suggests that bleach can be used as a substitute if these cleaners are not available to you. The bleach should contain 5%-9% sodium hypochlorite to be effective as a disinfectant. Follow the directions on the bottle for safe diluting and surface application. ((Centers for Disease Control – Cleaning and Disinfecting with Bleach))
