Cleaning is an after-operation service performed by operator/crew to keep the
vehicle in a state of readiness. Facilities and material available to operators for
vehicle cleaning can vary greatly in differing operating conditions. However, vehi-
cles must be kept as clean as available cleaning equipment, materials, and tactical
situations permit.

whenever caustic, toxic, or flammable cleaning solutions are used.

A fire extinguisher must be available and ready during all cleaning oper-
ations involving solvents.

Do not allow corrosion-removing cleaning compounds to contact painted
surfaces.
