To ensure the longevity of a hand-forged belt buckle and protect it from corrosion, it should be dusted regularly with a soft microfiber cloth and cleaned with a mild soap solution as needed. Immediate and thorough drying is essential after contact with moisture; it is also recommended to treat metal buckles with a suitable polish or wrap them in a cloth to protect them from scratches. Ideally, they should be stored hanging or flat in a cool, dry place free from high humidity.
