1. Regular Cleaning: Dust and wipe down the steel regularly with a soft polishing cloth. Avoid abrasive cloths that can scratch the surface, as scratches can lead to rust formation over time.

2. Cleaning Technique: When wiping the surface, use straight back and forth movements instead of circular motions to maintain a uniform appearance and shine.

3. Avoid Corrosive Products: Refrain from using corrosive chemicals such as chloride cleaners, abrasive cleaners, all-purpose cleaners, and chloride bleach. Instead, opt for warm water and mild soap for cleaning. Ensure thorough drying to eliminate moisture, which can cause corrosion.

4. Restoration: If you wish to restore your steel furniture to its original appearance, use an appropriate metal cleaner. Look for cleaners that are non-hazardous, non-toxic, and biodegradable to minimize environmental impact.

5. Removing Marks and Fingerprints: To remove marks and prevent fingerprint marks, consider using oil-based products like baby oil. These can help maintain the steel's appearance and protect it from smudges.

6. Preventative Maintenance: Regularly clean your steel furniture to prevent corrosive particles from accumulating on the surface, which can lead to reactions with the steel.

By following these care instructions, you can ensure that your steel furniture remains sturdy and aesthetically pleasing for many years to come. Proper maintenance will not only preserve its appearance but also contribute to its longevity, allowing you to enjoy your furniture for years to come.
