🧪 Bleach

Bleach is a corrosive oxidiser and is prohibited in both carry-on and checked baggage on all commercial flights without exception. If screeners find bleach in your bag, it will be confiscated immediately and you will not be allowed to take it on the aircraft in any form. There is no appeal or workaround.

Bleach is banned from all commercial passenger aircraft universally — this is not a regional rule but an international aviation standard set by ICAO and implemented by every major aviation authority including the TSA, EASA, CASA, and Transport Canada. No quantity is permitted in carry-on or checked baggage on a passenger flight.

Do not attempt to bring it through — bleach will be detected and confiscated. Dispose of it in a trash bin before you reach the security checkpoint. Trying to conceal it in another container is both a security violation and dangerous, since bleach can react with other substances and leak.

Purchase bleach or a bleach-based cleaning product after you arrive at your destination — it is available in supermarkets virtually everywhere. If you need a sanitising product for travel, small bottles of rubbing alcohol or multi-surface disinfectant wipes under 100ml are permitted in carry-on and are effective alternatives for most cleaning tasks.
