Here's what the manufacturer says...

How it Works - Zerust products protect against rust by releasing an invisible, non-toxic, non-reactive, and odorless corrosion-inhibiting vapor. This vapor protects metal components from corrosion for up to five years. Protect a range of metal items including those created from aluminum, brass, copper, iron, nickel, steel, and silver.
