How to Care for Engraved Copper, Brass, and Steel Coins, Keychains, and Pendants | MaxCoins
Engraved metal accessories continue to grow in popularity due to their durability, expressive appearance, and the ability to personalize them with meaningful symbols, dates, or custom messages. At MaxCoins, we create high-quality engraved coins, custom keychains, and pendants crafted from copper, brass, and stainless steel. Each product is made using deep relief laser engraving, followed by professional manual finishing, precision edge refinement, and final polishing to achieve maximum visual clarity and long-lasting quality.
Different metals require different approaches to maintenance. Copper and brass naturally oxidize over time, developing a darker patina. At MaxCoins, these metals can also be intentionally treated with a decorative patina to create an antique or vintage effect. Patina highlights the relief engraving, enhances depth, and adds a unique artistic character. Because patina is part of the artistic finish, it should be protected during the cleaning process.
Polished stainless steel accessories require minimal care. Stainless steel is naturally resistant to corrosion and tarnishing, so maintaining its appearance usually takes no more than wiping it with a soft cloth. However, it is essential to avoid abrasive cleaners or harsh chemicals to preserve the polished surface and keep the engraved details sharp.
One of the most distinctive features of MaxCoins products is the manufacturing process. Deep relief laser engraving allows for extremely detailed artwork with high contrast and long-term durability. After engraving, each accessory undergoes manual finishing performed by skilled artisans. This includes delicate surface smoothing, contour refinement, and final polishing that creates a protective glossy layer and enhances the visibility of the engraved elements. This production method ensures the accessories maintain their quality even under daily use.
To keep your engraved coins, pendants, and keychains in pristine condition, it is recommended to store them individually — preferably in a soft pouch or protective case. This prevents scratches, removes unnecessary exposure to moisture, and keeps the surface clean. Cleaning depends on the metal type: stainless steel pieces can be washed with mild soapy water and dried with a soft cloth. Copper and brass items, especially those with patina, should be cleaned very gently. A dry microfiber or flannel cloth is usually enough.
Accessories with intentional patina should never be treated with commercial metal polishes, as these may remove or damage the decorative finish. If you prefer bright, polished copper or brass without patina, occasional gentle polishing with a soft cloth will help maintain their natural shine without affecting the relief engraving.
