Clorox is an effective cleaner and disinfectant, but it can also be hazardous if not used properly.

Clorox bleach is commonly used for cleaning and disinfecting surfaces and fabrics. In fact, most of the world's health organizations recommend using bleach to help control the spread of pathogens that can make people sick. The American Academy of Pediatrics reports, though, that bleach causes more injuries and illnesses children than any other household cleaner. It is important for consumers to understand the potential hazards of bleach in order to avoid accidents or injuries.

Health Problems

Clorox bleach can be harmful to humans if ingested or inhaled, or if it stays on the skin for too long. According to the EPA's Materials Data Safety Sheet, if Clorox makes prolonged contact with the skin, it can cause skin irritation. If you swallow bleach or it gets into your eyes, it can cause serious symptoms, including nausea and vomiting, and temporary blindness. Exposure to bleach vapors and mist can aggravate the symptoms of certain heart and respiratory conditions, such as asthma, emphysema or chronic bronchitis.


Bleach is an oxidizing agent, meaning that it will cause metal corrosion. According to Clorox, when bleach is diluted in water, it breaks down into salt and water very quickly. If you are storing bleach solution in a spray bottle with metal parts, over time the bleach can corrode the metal parts in the trigger mechanism. With prolonged contact, undiluted Clorox can cause metal to pit and discolor.

Toxic Gases

When mixed with other chemicals, such as ammonia, vinegar, acids or other cleaners containing chlorine, Clorox produces hazardous gases that can be harmful or even fatal. Clorox should only be diluted with water, according to the specific instructions on the bottle.

Toxic Chemicals

Do not use Clorox bleach on pressure-treated wood manufactured before February 2002. Before that date, most pressure-treated wood was made with chromated copper arsenate, or CCA, a type of arsenic. When you use bleach on this type of wood, the CCA combines with the bleach to form toxic hexavalent chromium. Hexavalent chromium is very dangerous, and can cause cancer and other health problems.

Removing Dye from Fabric

While one of the reasons that many people use Clorox is its ability to remove stains and discoloration from white fabrics, Clorox will remove dyes from fabric. Be careful not to let Clorox bleach have any contact with colored fabrics, unless you want to remove the color.

Clorox Safety Tips

You can avoid accidents or injuries from Clorox by following the use and safety precautions listed on the bottle. Always keep bleach away from children, even if it has a child-proof cap. Never use bleach without diluting it, and let surfaces dry completely before allowing children and pets near them. Use Clorox in a well-ventilated area, and wear a mask if you will be using bleach for an extended period of time or if you are sensitive to the fumes.
