Bleach is a powerful disinfectant that kills many types of potentially harmful germs. It's also used to clean household surfaces, such as toilets. While it's a useful product, bleach can be dangerous when ingested and comes into direct contact with the eyes or skin. It can also react with other chemicals to create toxic fumes that may affect lungs, cause chemical burns, or even lead to death if inhaled. Bleach is a strong irritant, and peeing into a toilet that's been cleaned with bleach can lead to splashes of the chemicals that may sting the eyes and skin.
Bleached urine can be a sign of infection, and it's important to see a doctor if you experience red or pink pee. It can also be a symptom of a rare condition called porphyria, which causes the breakdown of blood cells in the body.
If you have a condition that causes broken down blood to appear in the urine, such as hemolytic uremic syndrome (HUS), your pee might turn brown or red. In some cases, this is a normal occurrence, but if it's accompanied by abdominal pain, rashes or fever, you should see your doctor right away.
Bleach should never be mixed with ammonia, as it can lead to a deadly chemical reaction. The active ingredient in bleach is sodium hypochlorite, and when it mixes with ammonia it produces a toxic type of chlorine gas that can damage the lungs. Bleach and urine can also interact to produce chloramine gas, which resembles mustard gas and is extremely irritating.
