Metal filing cabinets are prone to rusting in humid environments. To prevent rust, regularly inspect the cabinet surfaces for scratches or areas where the coating has peeled off. If localized damage is found, promptly repair it using anti-rust paint that matches the cabinet's color; ensure all rust is thoroughly removed and the area is dry before applying the paint.
For cabinets frequently exposed to humidity, place desiccants inside and replace them regularly. Additionally, maintain an appropriate gap between the cabinet and the wall to facilitate air circulation. If condensation forms on the cabinet surface, wipe it dry immediately.
Wooden filing cabinets require protection against insects and mold. Place camphor wood blocks or natural insect repellents inside, avoiding direct contact between chemical repellents and the wood. Periodically check for mold spots; if any are found, wipe them immediately with a soft cloth dampened with a small amount of diluted white vinegar, then allow the area to dry thoroughly.
