Troubleshooting

Residue remains after LUXI Purple in recesses

LUXI Purple can remain in complex geometry if overapplied because it has higher useful adhesion.

Clean bright raised relief with neutral polishing residue trapped in narrow recesses.

Symptoms

  • LUXI Purple residue remains in recesses, undercuts or fibre-contact zones.
  • The surface is polished but not clean enough for coating or final inspection.

Likely causes

  • LUXI Purple was overapplied.
  • The brush or thread carried compound deep into the geometry.
  • Cleaning was not matched to the recess shape.

Checks

  • Inspect under good light or magnification.
  • Check whether residue is trapped in pores, texture, prongs or undercuts.

Recommended fixes

  • Use minimal compound, clean carefully, inspect before coating and use controlled cleaning.
  • Do not extend ultrasonic time aggressively without checking material and coating risk.

Prevention

  • Keep the brush or thread lightly charged.
  • Clean during the process rather than after heavy buildup develops.
