DEF, Diesel Exhaust Fluid

[davidbrady]

Folks,

Looks like there's another hazard at the Truck Stop, DEF. Try to avoid splashing any DEF onto your wheels. Our rigs aren't new enough to require DEF but that doesn't mean we can't drive thru a puddle of the stuff spilled on the pavement.

DEF is basically urea which is basically aqueous ammonia which will work it's way thru the protective layer of aluminum-oxide and attack the underlying aluminum of your wheels! Stay clear!
