Cleaning products you should never mix
Mixing some common household cleaners can release dangerous gases. The safest rule is simple: use one product at a time, rinse surfaces in between, and keep everything in its original container.
| Never mix | With | Because it |
|---|---|---|
| Bleach | Ammonia (including some glass and multi-surface cleaners) | Releases toxic chloramine vapors |
| Bleach | Vinegar or other acids, including some toilet bowl and rust cleaners | Releases chlorine gas |
| Bleach | Rubbing alcohol | Can form chloroform and other harmful compounds |
| Hydrogen peroxide | Vinegar | Forms peracetic acid, which can irritate skin, eyes and lungs |
| One drain cleaner | A different drain cleaner | Can react violently, with heat and splashing |
| Any two cleaners | In the same bucket or bottle | Unknown reactions; use one product at a time and rinse between |
