Some auto parts stores have it, as do some hardware stores. It's often used to winterize RVs and boats.

Here's one example: http://www.peakantifreeze.com/rvmarine.htm

PS Save the Everclear, it's way too expensive for this type of application ;^)

The g.f. picked up a used portable basketball hoop for the kids. This is
the type with the big plastic base that you fill with water. The label
on the pole suggests adding "non-toxic" antifreeze to the water. Is this
an auto parts store item? Or just pour in a few quarts of everclear?
