CAUTION: Avoid contact with eyes. In case
of contact, immediately flush eyes with large
amounts of water for a minimum of 15 minutes.

(MSDS) for additional information.
IMPORTANT: If DEF is spilled or contacts any surface
other than the storage tank, immediately clean
the surface with clear water. DEF is corrosive to
painted and unpainted metallic surfaces and can
distort some plastic and rubber components.
Spilled DEF, if left to dry or if only wiped
away with a cloth, leaves a white residue.
Improperly cleaned DEF spill can interfere with
diagnosis of Selective Catalytic Reduction
