Brass is an alloy of copper and zinc, with an attractive gold-like colour. Naval brass is premium grade, with the addition of 1% tin, which increases its resistance to corrosion while providing a stronger structure. The surface is uncoated to embrace the natural patina that will develop over time.
Brass has a tendency to oxidise quickly when exposed to air or direct contact with skin. Our brass is uncoated to embrace the oxidisation and resulting patina as a natural and beautiful part of the life of the brass product. As such, we do not recommend polishing. If however if you prefer to remove the patina, it is important to clean the brass using a brass polish such as Brasso, and to clean the entire surface at once. After cleaning, use a non-agressive, multipurpose cleaning solvent to degrease the product such as CT1 Multi-Solve, applied with a clean soft cloth. Do NOT use abrasives, ammonia, products containing ammonia, or any other corrosive cleaning solutions as this can damage the brass. Prevention is the best protection against surface scratches.
