  1. Pour Zerust ICT 620-RR into a container with the rusted parts (fully cover parts).
  2. Soak the rusted parts in Zerust ICT620-RR for ~30 minutes for light rust and overnight for heavy, flaking rust. *DO NOT spray the rusty parts with ICT 620-RR—the product will not work this way.
  3. Rinse the parts with de-ionized water and inspect.
  4. Wipe parts with a dry cloth if needed (some black carbon residue may remain on the metal surface).
  5. Repeat soaking if rust remains, and re-rinse.
  6. Air dry. Check for areas where solution may have pooled, re-rinse and dry.
  7. Package parts in Zerust products to prevent the recurrence of rust.
