(Image credit: Shutterstock) When it comes to day-to-day household chores, I usually rely on natural, non-toxic cleaning products to do the job.Whether it’s my trusty white vinegar and baking soda to tackle everyday grime or hydrogen peroxide to lift tough marks and mold, these eco-friendly alternatives are extremely popular.However, it's important to know that not all natural ingredients work well together. Although white vinegar and hydrogen peroxide are household favorites, combining the two can be a lethal combo.So before you get out your cleaning caddy, here’s why you should never mix vinegar and hydrogen peroxide.What happens if you mix vinegar and hydrogen peroxide A blue bottle of 3% hydrogen peroxide, green box of baking soda, a yellow microfibre cloth (Image credit: Future)While vinegar vs. hydrogen peroxide offer distinct advantages when used separately, combining acetic acid (vinegar) and hydrogen peroxide in a spray bottle creates peracetic acid (peroxyacetic acid).Essentially, this is a corrosive and toxic chemical that can irritate the skin, cause watery eyes, and affect your respiratory system (especially with long-term use).If you do experience any of these symptoms, however, be sure to seek medical attention immediately.

Just spray the area gently using one cleaner at a time — starting with the white vinegar — and let it sit for about 15 minutes before wiping the surface clear with a clean microfiber cloth.Since white vinegar alone can’t effectively kill bacteria or germs, hydrogen peroxide saves the day — and good bleach substitute. Similarly, spray the same spot with hydrogen peroxide, letting it rest for a couple of minutes, before wiping it thoroughly clean.Not only will your household surfaces remain both spotless and fully sanitized, but you’ll eliminate any harmful toxins.For more top tips on natural products, check out cleaning vinegar vs white vinegar: Why you need to know the difference (and what to avoid).
