Most commercially available antifreeze contains ethylene glycol, a potentially toxic chemical that is poisonous and can be lethal if ingested. Keep antifreeze away from children and pets who may find the bright green color and sweet smell appealing and drink it.
Check your owner’s manual for information on when to change antifreeze. Most manufacturers suggest that you change your antifreeze and flush the cooling system every two years or 24,000 miles, but check your owner’s manual to see what’s recommended for your car. The longer the interval, the less waste. You can use an antifreeze tester from your local auto supply store to determine whether your antifreeze is still doing its job.
Regularly check your radiator, reservoir, and all hoses for leaks. Repair any leaks immediately.
Consider using less-toxic antifreeze. Less toxic antifreeze is made of propylene glycol—rather than ethylene glycol—and is purple in color. It provides the same protection and is readily available at a cost comparable to conventional antifreeze.
Never drain antifreeze from your car onto the street, and do not dispose of antifreeze down the drain, in sewers, or into streams.
Have your antifreeze changed by a professional who offers recycling of the used antifreeze as part of the service.
Bring your used antifreeze to BWPRR's SAFE disposal events.
If you cannot find an alternative disposal option for your antifreeze, you can dry it out with kitty litter, newspaper, or another absorbent material prior to discarding in the trash. Empty antifreeze containers can be recycled with other metal, glass, and plastic.
