One coupon was coated with each of the six supplied inks. These included Dykem Stop Off, Markal Valve Action Paint marker, Nu-Mark marker, Sharpie permanent marker, Sakura Coatings Product Company Solid Marker and the Avery Marks-A-Lot permanent marker (black).

| Markal | Worked well |
| Nu-Mark | Worked well |
| Sharpie | Worked well - slight blue residue left |
| Sakura | Worked well under 1 minute |
| Avery | Worked well |
Success Rating:
Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.Conclusion:
The Vertec Bio Gold #3 worked on all six inks.
