1. Appropriate use of iron sandpaper for maintenance. For example, iron crafts have caused serious scratches and fire burns. We can use iron sandpaper to polish the appearance to prevent further oxidation damage.

 

2. Keep away from strong acids and bases. Special attention should be paid to prevent iron crafts accessories from contacting with strong acids, strong alkalis and other substances. Do not use hard objects or sharp objects to scratch the appearance of iron crafts that have been touched.
