Instructions for Use

Pre or post cleaning

  • Spray the surfaces to be cleaned liberally with the cleaner, and either wipe off or allow to air dry.
  • Alternatively, soak a clean cloth with the cleaner and wipe the part clean. Allow the part to dry thoroughly before applying the penetrant.

Penetrant removal

  • Wet a clean dry lint-free cloth with the cleaner and wipe the inspection area.
  • DO NOT spray or apply directly to the inspection surface as this will impair sensitivity.
