How to Clean and Maintain Pure Copper Items at Home
2025-12-08
Pure copper items, from stunning cookware to elegant décor, bring timeless beauty and functionality into your home. However, their signature warm glow can tarnish over time when exposed to air and moisture. Proper care is essential to preserve both their appearance and material integrity. At INT METAL, we specialize in crafting premium, solid pure copper products built to last for generations. Understanding your metal is the first step in its care. Our items, like the Heritage Collection Tea Kettle, are made from 3mm thick, 99.9% pure copper with a hand-hammered finish and a seamless, food-grade tin lining, ensuring durability and performance.
Routine Cleaning & Maintenance Guide
For daily upkeep and tarnish removal, follow these simple steps:
-
Gentle Cleaning: Mix mild dish soap with warm water. Use a soft cloth or sponge to wipe the surface, then rinse thoroughly and dry immediately with a microfiber cloth to prevent water spots.
-
Tarnish Removal (Natural Method): Create a paste from equal parts flour, salt, and white vinegar or lemon juice. Apply, let sit for 15-30 minutes, then gently rub in the direction of the grain and rinse. This method is ideal for light to moderate tarnish.
-
Tarnish Removal (Commercial Polish): For heavier tarnish, use a high-quality, non-abrasive pure copper polish. Apply a small amount with a soft cloth, following the product's instructions, and buff to a shine.
-
Protective Coating: After polishing, apply a thin layer of beeswax or a dedicated lacquer (for decorative items only) to slow down future tarnishing. Never use harsh abrasives, steel wool, or dishwasher cleaning on pure copper, as this will cause permanent scratches.

Pure Copper FAQ
Q: Will cleaning my pure copper item reduce its value or damage it?
A: Not if done correctly. Proper cleaning removes only the superficial layer of copper oxide (tarnish). The patina that forms on pure copper is a natural process and can be removed without harming the solid metal underneath. INT METAL's substantial gauge ensures you can safely maintain your item for decades.
Q: Can I use my INT METAL pure copper cookware on an induction hob?
A: No, standard pure copper is not magnetic and will not work on induction cooktops. Our cookware is designed for gas, electric, ceramic, and oven use. For induction compatibility, we offer a separate line with an integrated magnetic base plate—please check specific product descriptions.
Q: How often should I re-tin the lining of my copper pot or bowl?
A: The frequency depends on usage. With moderate home use, a high-quality tin lining from INT METAL can last several years. Re-tinning is necessary when you see consistent wear, with the copper base becoming visible. We recommend contacting a professional retinning service when this occurs.
