1. Regular CleaningRegardless of the type of coating you have, it's important to clean your handles, knobs, and door handles regularly. Use a soft cloth and mild cleaners to avoid damaging the surface. Harsh cleaning products can scratch or degrade the coating's finish.2. Protect Against WearAvoid exposing your brass products to harsh chemicals or extreme temperature changes, as this can negatively affect the coating. If the products are used in areas with high humidity, such as bathrooms, wipe them down regularly to prevent stains and corrosion.3. Polishing and ProtectionFor chrome and nickel coatings, regular polishing with a microfiber cloth can help maintain a mirror-like surface. For copper and antique coatings, applying a protective wax can help extend their lifespan and protect against oxidation.4. Avoid Scratches and DamageWhen installing or maintaining, be careful with tools that could scratch or damage the coating. If possible, use protective tape or cloth between the tools and the surface to prevent accidental damage.
