Before You Start
Before cleaning, identify the finish and ensure you won’t damage sensitive surfaces. Test in a hidden spot first to confirm the cleaner won’t strip or discolor the metal.

Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Dull or matrix-like spots | Oxidation or residue buildup | Gentle polishing with microfiber cloth and brass cleaner | Regular light cleanings; avoid harsh abrasives |
| Streaks after polishing | Lack of thorough drying | Dry with microfiber until no moisture remains | Dry thoroughly after every cleaning |

Common Mistakes
- Using abrasive cleaners on antique finishes, which can scratch and dull the surface.
- Over-cleaning to the point of removing interior patina that adds historical value.
- Not drying hardware completely, leading to water spots or corrosion.
- Rushing reassembly, which can misalign hinges or screws and cause functional issues.

Gently approach each piece, especially if it has a unique patina. Work in small areas to monitor changes closely. Use the soft-bristle brush set to reach ornate areas without applying excessive pressure. When applying cleaners, avoid oversized amounts and let the product do the work. A final wipe with a dry microfiber cloth will help preserve a natural, warm glow.
