Hardware, fabric linings and leather panels need separate tools and appropriate protection. Keep metal-treatment residue and transferred dyes away from adjoining surfaces.
Check first
- Identify whether the hardware is plated, solid metal or coated.
- Test the lining fabric for colour transfer.
- Protect adjacent pale leather and edge paint.
- Prepare separate cloths, brushes and containers for each area.
Working sequence
- Remove dry particles first.
- Begin with the lowest-risk area.
- Lift residue promptly and maintain ventilation.
- Wait until the materials are stable before closing the bag.
Aggressive polishing is not a reliable remedy for hardware scratches. An over-wet lining can transmit moisture to the outer leather. Keep all liquid applications within an area where they can be recovered.
