Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays
For vehicles with high gloss
surfaces or vehicle displays, use a
microfiber cloth to wipe surfaces.
Before wiping the surface with the
microfiber cloth, use a soft bristle
brush to remove dirt that could
scratch the surface. Then use the
microfiber cloth by gently rubbing to
clean. Never use window cleaners
or solvents. Periodically hand wash
the microfiber cloth separately,
using mild soap. Do not use bleach
or fabric softener. Rinse thoroughly
and air dry before next use.
