To help establish good cleaning techniques throughout your polishing process:

  1. You must remove residual ceramic and epoxy residue on every lapping film to maintain its cutting and polishing effectiveness. To clean lapping film, spray the film with a mild isopropyl alcohol (IPA) solvent, 90% or better. Next, use a lint-free wipe with distilled water or dry the film with an air gun. Now the film is primed and ready for the next polishing round.
  2. Lapping film must be cleaned, as noted above, prior to each use. The only exception is the final films – these must be cleaned with a thorough wipe down using a lint-free wipe and distilled water.
