Window cleaner poisoning

Window cleaner poisoning occurs when someone swallows or breathes in large amounts of window cleaner. This can happen by accident or on purpose.

This article is for information only. DO NOT use it to treat or manage an actual poison exposure. If you or someone you are with has an exposure, call your local emergency number (such as 911), or your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.

Home Care

Seek medical help right away. DO NOT make the person throw up unless poison control or a health care provider tells you to.

If the person swallowed the window cleaner, give them water or milk right away, unless a provider tells you not to. DO NOT give anything to drink if the person has symptoms that make it hard to swallow. These include vomiting, convulsions, or a decreased level of alertness. If the person breathed in fumes of cleaner, move them to fresh air right away.

Before Calling Emergency

Have this information ready:

  • Person's age, weight, and condition
  • Name of the product (ingredients, if known)
  • Time it was swallowed
  • Amount swallowed

Poison Control

Your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This hotline number will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

What to Expect at the Emergency Room

Take the container to the hospital with you, if possible.

The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.

The person may receive:

  • Blood and urine tests
  • Breathing support, including a tube through the mouth into the lungs, and a breathing machine (ventilator).
  • Bronchoscopy. Camera down the throat to see burns in the airways and lungs.
  • Chest x-ray
  • EKG (electrocardiogram, or heart tracing)
  • Endoscopy. Camera down the throat to look for burns in the esophagus and the stomach.
  • Fluids through the vein (by IV)
  • Medicines to treat symptoms
  • Washing of the skin (irrigation). Perhaps every few hours for several days.

Outlook (Prognosis)

How well someone does depends on the ingredients of the window cleaner they swallowed, how much they swallowed, and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery.
