Can I mix bleach and vinegar?

Concerns & risks

You were trying to get a stubborn shower really clean, and you thought mixing bleach and vinegar would make a super cleaner.

Everyday mishaps add up.

Causes & evidence

Never: bleach plus acids like vinegar releases chlorine gas. See cleaning chemical safety.

What to do

1. Never mix bleach with acids or ammonia.
2. Use one product at a time.
3. Ventilate.

Common mistakes: Common mistakes: thinking more products means more power. Mixing can create dangerous gases that irritate the eyes, nose, throat and lungs. Some products already contain acids or ammonia, so read labels carefully; toilet bowl cleaners and some glass cleaners are examples. Don't use two products back-to-back on the same surface without rinsing well with water in between. Open windows and run a fan. Wear gloves if the label says so. Store cleaners in their original containers so you always know what's in them. If you feel unwell after cleaning, leave the room and get fresh air.

Speed Man tip: Rinse between products.

Wrap-up: Never mix. One at a time. Air.
