Backpack buckles are generally divided into buckles (also known as side buckles), day buckles, ladder buckles, hook buckles, rope buckles, and some more special uses. Now let's introduce the characteristics, uses and strengths of these buckles.

Metal utensils will oxidize to varying degrees over time, whether it is iron, silver, or inert gold. High-purity gold will lose its luster after being worn for a long time, and the surface will be covered with other impurities.

We soaked the cobra buckle in concentrated salt water for 48 hours to allow it to corrode and oxidize. After trying various methods to clean up the recovery buckle, I finally found that the "silver grinding rod" is very effective. The silver grinding rod has two sides, the thick side is used to remove oxides and stains on the metal surface, and the fine side is used for polishing. After sanding and polishing, it looks brand new!

If the belt buckle is made of plastic material, there is no need to worry about rust and oxidation, and it is cost-effective and has a long service life.
