The following measures are recommended for the care and cleaning of polished steel knee bosses: - Cleaning: Use a damp cloth and soapy water to remove dirt. It is important to thoroughly dry the surface after each cleaning to prevent rust formation caused by moisture.
- Rust prevention: Regularly apply a thin layer of protective oil, such as linseed oil, gun oil (e.g., Ballistol), or special metal wax. This forms a barrier against oxidation and moisture.
- Rust removal: If rust spots have already formed, they can be carefully removed with fine steel wool, a wire brush, or metal polishing compound.
- Storage: Store the knee bosses in a dry place to protect them from humidity.
