How to dispose of Antifreeze & Coolant in California
California rules
Contact your county household hazardous waste program or a coolant recycler. Antifreeze is not a California universal-waste category; confirm site acceptance and do not mix it with used oil.
General steps
- Never pour antifreeze down drains or on the ground — it's toxic to animals and children.
- Collect used antifreeze in a sealed, labeled container.
- Take to an auto parts store — many accept used antifreeze for free (AutoZone, O'Reilly).
- Check your local hazardous waste facility for antifreeze recycling.
- Used antifreeze can be professionally recycled and reconditioned for reuse.
