What is the best way to protect piano hinges from corrosion?

Keeping piano hinges clean and properly lubricated is the best way to protect them from corrosion. This practice helps to remove any dirt, debris, or moisture that could otherwise contribute to rust or deterioration of the hinge material. Regular lubrication creates a barrier to moisture, which is one of the primary causes of corrosion. Proper lubrication also ensures smooth operation of the hinge, preventing wear and damage over time.

Applying paint regularly can provide some level of protection, but it may not be as effective as consistent cleaning and lubrication. Paint can chip or wear off, exposing the metal underneath to the elements. Storing hinges in a dry area can help to some extent, but it does not address the potential for corrosion when the hinges are in use or exposed to various conditions. Using steel wool for cleaning can be abrasive and may inadvertently scratch or damage the surface, leading to more opportunities for rust development. Therefore, maintaining cleanliness and lubrication is the most reliable method for safeguarding piano hinges from corrosion.
