How to prevent metal zipper pencil case from rusting

Metal zipper pencil cases are prone to rust due to moisture or contact with water. To prevent rust, you can take the following measures:

Keep dry: Keeping the pencil case dry is the most effective way to prevent rust. Avoid placing the pencil case in humid places, such as bathrooms, basements and other places with heavy humidity.

Clean regularly: Wipe the metal parts with a dry cloth regularly to remove dust and moisture and keep the metal surface clean. Avoid long-term accumulation of moisture.

Use rust inhibitors: You can use a special anti-rust spray or anti-rust oil to apply it to the metal parts to form a protective film to prevent moisture in the air from contacting the metal surface.

Avoid contact with moisture: Try to avoid placing the pencil case in a water-containing environment. If it gets wet accidentally, wipe it dry immediately.

Apply clear nail polish: Apply a layer of clear nail polish on the metal surface, which can form a thin film to prevent moisture from directly contacting the metal.

Use moisture-proof bags for storage: When not in use, you can put the pencil case in a moisture-proof bag to avoid direct contact with humid air.

Avoid contact with corrosive substances: Avoid contact between the pencil case and corrosive substances such as acids and alkalis, especially in a humid environment, as these substances can easily accelerate metal rust.

Through these measures, the service life of the metal zipper pencil case can be effectively extended to prevent it from rusting.
