Polish Copper: 400?800?1500?2000 Grit

Copper surfaces—whether cookware, jewelry, or hardware—tarnish and lose shine quickly. To restore their warm glow, sand progressively with 400 ? 800 ? 1500 ? 2000 grit, followed by polishing compound. This sequence removes oxidation, evens scratches, and prepares copper for a reflective finish.

Why Sand Copper

Copper is soft and prone to scratches. Polishing paste alone can’t fix deeper damage. A structured sanding ladder gradually smooths imperfections, leaving a clean surface ready for compound polishing.

Tools & Materials

• 9×11 in wet/dry sandpaper sheets: 400, 800, 1500, 2000 grit
• Sanding block or foam pad
• Spray bottle with water
• Copper polishing compound
• Buffing wheel or microfiber cloth
• PPE: gloves, respirator, safety glasses

Recommended Grit Sequence

• 400 grit — Removes tarnish, scratches, and surface damage.
• 800 grit — Refines surface, smooths scratches.
• 1500 grit — Prepares surface for high gloss.
• 2000 grit — Pre-polish clarity, ready for compound.

Step-by-Step: Copper Polishing

1. Clean copper. Remove grease and dirt with soap or degreaser.
2. Sand at 400 grit. Start with 400 grit (25-pack) wet to cut through tarnish and pitting.
3. Step to 800 grit. Switch to 800 grit (50-pack). Sand evenly until surface looks smoother.
4. Refine at 1500 grit. Use 1500 grit (100-pack) to bring satin finish.
5. Final sanding at 2000 grit. Finish with 2000 grit (25-pack). Surface should now look pre-polished.
6. Polish. Apply copper compound with cloth or buffing pad until mirror gloss appears.
7. Protect. Seal with wax or lacquer to reduce tarnishing.

Special Cases

Antique copper: Sand lightly to preserve patina—avoid full shine unless restoring.
Heavy corrosion: Start coarser (220 grit) before 400 ? 800 ? 1500 ? 2000.
Jewelry pieces: Use folded sandpaper for small details.

Pro Tips

• Sand wet to reduce clogging and scratching.
• Alternate sanding directions to confirm scratch removal.
• Work gently—copper is soft and sands quickly.
• Buff slowly—too much heat darkens copper.
• Seal polished copper quickly—oxidation returns fast.

Aftercare

• Wipe regularly with microfiber to slow tarnish.
• Reapply wax or lacquer as needed.
• Touch up with 2000 grit + polish when shine dulls.

FAQs

• Can I polish without sanding? Only for light tarnish—scratches need sanding.
• Why stop at 2000 grit? Beyond this, polishing compound works faster for gloss.
• Will sanding damage copper? No—only microns removed if done carefully.
• What’s best to seal copper? Clear lacquer or microcrystalline wax.
