All surfaces must be considered dirty and must be cleaned prior to the application of markings. Recommended cleaning procedures for specific surfaces are listed below.
Plastics and Glass
Saturate a clean cloth with a 2 to 1 mixture of water and isopropyl alcohol and wipe the surface. (Cleaners such as
Windex Window Cleaner may be used.) Wipe the surface with a dry, clean, lint-free cloth.
Painted Metals and Base Metals
These surfaces must be cleaned with asolvent such as: E.I. DuPont Prep-Sol Cleaning Solvent 39195, Xylol, VM&P,
Naptha, or Lacquer Thinner. Dry the surface with a lint-free cloth before the solvent evaporates. Freshly painted surfaces
