Is It OK to Mix Bleach and Vinegar?
No, never mix bleach and vinegar. This combination produces chlorine gas, which is toxic and can cause respiratory damage, eye irritation, and other serious health effects. Use these cleaners separately and ensure surfaces are rinsed between applications.
Key Takeaways
- When bleach (sodium hypochlorite) mixes with vinegar (acetic acid), a chemical reaction produces chlorine gas.
- Even opening containers of both cleaners in an enclosed space can create low-level exposure.
- If you accidentally mix these chemicals, leave the area immediately and ventilate.
Explanation
When bleach (sodium hypochlorite) mixes with vinegar (acetic acid), a chemical reaction produces chlorine gas. Even small amounts of chlorine gas can irritate the eyes, nose, and throat. Higher concentrations can cause severe respiratory damage.
This reaction can happen accidentally when switching cleaners without rinsing, or when residual bleach on a surface contacts vinegar. Always rinse surfaces thoroughly with water between using different cleaning products.
Mixing bleach with other acids like lemon juice or some bathroom cleaners creates the same dangerous reaction. Bleach should also never be mixed with ammonia or ammonia-containing products, which produces toxic chloramine gases.
Things to Know
- Even opening containers of both cleaners in an enclosed space can create low-level exposure.
- If you accidentally mix these chemicals, leave the area immediately and ventilate.
- Symptoms of chlorine gas exposure include coughing, chest tightness, and watery eyes.
