Antifreeze is more toxic after it has been used in your car.  It contains poisonous chemicals that can be deadly if swallowed by humans or pets.  Lakes and streams can be threatened if antifreeze is poured down storm sewers.


  • Don’t place it in the trash
  • Don’t pour it down storm sewers
  • Don’t let it drip on the ground
  • Don’t flush it into septic systems
  • Don’t use it to keep ice-fishing holes ice free
  • Don’t mix it with oil


For a fee, some service stations accept antifreeze for reconditioning and reuse.  Call first.


Antifreeze may be safely disposed of by taking it to:
