To protect the FRW chainmail collar made of untreated steel from rust, it should be regularly maintained: - Cleaning: Remove dirt with a damp cloth and soapy water, then dry thoroughly immediately.
- Rust prevention: After each use, especially in damp conditions, apply a thin layer of protective oil (such as linseed oil, gun oil, or Ballistol).
- Storage: Store the chainmail collar in a dry place.
- Rust removal: If rust has already formed, it can be carefully removed with steel wool or a wire brush before re-oiling the metal.
