:079 Car Antifreeze


Credit: Sierra Antifreeze

Suggested Review – none

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:079 Tip: Typical car antifreeze (ethylene glycol) can be extremely dangerous when consumed. As little as one teaspoon can be fatal to cats, and two tablespoons full is dangerous for children. Propylene glycol tastes sweet so some manufacturers are adding a bitter tasting compound to it to make it less palatable.

An alternative that is safer for the environment and considered non-toxic (although anything can be toxic if you consume enough) is propylene glycol. It is becoming widely available at auto supply stores.


Additional Information

Sierra Antifreeze is one brand of propylene glycol antifreeze. They have some good questions and answers at:  http://www.sierraantifreeze.com/benefit.html
