How to Clean and Care for Your Copper Products
Copper is a beautiful, natural material that develops character over time. Whether you prefer the bright shine of polished copper or the rich patina of aged copper, proper care will keep your copper pieces looking their best for years to come.

Natural Cleaning Methods
Lemon and Salt Method
Cut a lemon in half and sprinkle salt on the cut surface. Gently rub the lemon over the copper surface in circular motions. The natural acidity of the lemon combined with the abrasive salt will remove tarnish and restore shine. Rinse thoroughly with warm water and dry immediately with a soft cloth.
Vinegar and Salt Solution
Mix equal parts white vinegar and salt to create a paste. Apply the paste to tarnished areas and let sit for 15-30 minutes. Gently scrub with a soft cloth or sponge, then rinse completely and dry thoroughly.
Ketchup Polish
Believe it or not, ketchup works wonders on copper! Apply a thin layer of ketchup to the copper surface and let it sit for 5-10 minutes. The acidity will break down tarnish. Rinse well and buff dry with a soft cloth.

Maintaining Your Copper Finish

Brushed Copper Finish

Dark Patina Finish
For Polished Copper
- Clean regularly with mild soap and warm water
- Dry immediately after cleaning to prevent water spots
- Apply a thin coat of mineral oil or specialized copper wax to protect the shine
- Buff gently with a microfiber cloth for extra luster
Protecting Polished Copper with Wax
After polishing your copper to a brilliant shine, applying a protective wax coating is essential to maintain that luster and slow down tarnishing. Here's how to do it properly:
Choosing the Right Wax
- Renaissance Wax: Museum-quality microcrystalline wax that provides long-lasting protection without yellowing
- Carnauba Wax: Natural, hard wax that creates a durable protective barrier and enhances shine
- Specialized Copper Wax: Products like Copper Brite Wax or similar formulations designed specifically for copper
- Beeswax-based Products: Natural option that provides moderate protection with a warm finish
How to Apply Protective Wax
- Clean and Polish First: Ensure copper is completely clean, polished, and free of tarnish before waxing
- Dry Thoroughly: The surface must be completely dry - any moisture will be trapped under the wax
- Apply Thin Layer: Use a soft, lint-free cloth to apply a very thin, even coat of wax in circular motions
- Let It Cure: Allow the wax to dry for 10-20 minutes (check product instructions)
- Buff to Shine: Using a clean microfiber cloth, buff the surface in circular motions until it gleams
- Second Coat (Optional): For maximum protection, apply a second thin coat and buff again
Wax Maintenance Schedule
- Indoor items: Reapply wax every 3-6 months depending on handling and exposure
- Outdoor items: Reapply every 2-3 months or after heavy rain/weather exposure
- High-touch items: Reapply monthly for items that are frequently handled
- Clean gently between wax applications with a damp cloth only - avoid harsh cleaners that strip the wax
Benefits of Waxing
- Creates a barrier against oxygen and moisture that cause tarnishing
- Reduces fingerprints and smudges on frequently touched surfaces
- Enhances the depth and warmth of the copper's natural color
- Makes future cleaning easier - dirt and grime won't adhere as readily
- Extends the time between deep cleaning sessions
For Patina Finish
- Simply wipe with a damp cloth to remove dust and dirt
- Avoid harsh chemicals that might strip the patina
- Allow the natural aging process to continue
- The patina actually protects the copper underneath
- Waxing is optional for patina finishes but can add subtle depth and protection
What to Avoid
- Abrasive cleaners: Steel wool, scouring pads, or harsh chemical cleaners can scratch the surface
- Dishwashers: Never put copper items in the dishwasher - the heat and detergents can damage the finish
- Prolonged moisture: Always dry copper thoroughly to prevent spotting and accelerated tarnishing
- Ammonia-based cleaners: These can cause discoloration and damage
- Bleach or chlorine: Will cause severe discoloration and pitting
- Excessive wax buildup: Apply thin coats only - thick wax can look cloudy and attract dust
Outdoor Copper Care

For outdoor copper items like mailboxes, house numbers, and signs:
- Expect natural weathering and patina development - this is part of copper's beauty
- Rinse occasionally with water to remove dirt and debris
- If you prefer to maintain shine outdoors, apply a clear lacquer sealant or marine-grade wax (reapply every 2-3 months)
- The green patina that develops is a protective layer and a sign of authentic copper
- For coastal areas with salt air, increase waxing frequency to prevent accelerated corrosion
Quick Maintenance Tips
- Handle copper with clean, dry hands to minimize oils and fingerprints
- Store copper items in a dry place when not in use
- For daily-use items, a quick wipe with a soft cloth keeps them looking great
- Embrace the patina - it's a natural, beautiful part of copper's character
- Keep a maintenance log for waxed items to track when reapplication is due
