What Should I Do with Antifreeze?
Antifreeze is used to cool the engine. Most antifreeze is made by mixing distilled water with some kind of alcohol such as methanol, ethylene glycol, propylene glycol and glycerol. Glycerol has the advantage of being non-toxic while withstanding high temperatures and it is noncorrosive.
Antifreeze breaks down and forms an acid that corrodes the vehicle's cooling system. During normal use, antifreeze (including those made with glycerol) become contaiminated with fuel, metal particles, and grit.
A few municipalities accept antifreeze for a recycling program. However, you can bring antifreeze to the household hazardous waste collections.
