Contains methanol which is toxic and flammable. Never pour down drains or onto ground. Some formulations contain ethylene glycol (antifreeze) making them extremely toxic to pets.

Is windshield washer fluid really that dangerous?
Yes - methanol can cause blindness if ingested and ethylene glycol (in winter formulations) is highly toxic to pets. Even small amounts require proper disposal.
Can I make my own windshield washer fluid?
You can make safer alternatives using distilled water and small amounts of dish soap, but they won't have freeze protection or commercial cleaning power.
What's the difference between summer and winter washer fluid?
Summer fluid typically uses methanol, while winter fluid often contains ethylene glycol for freeze protection. Winter formulations are more toxic and require more careful handling.
