What the precautions for cleaning and maintaining desks and chairs?

Daily cleaning:

Wooden/steel tables and chairs: Wipe with a slightly damp cloth and avoid corrosive detergents.

Plastic tables and chairs: Spray with neutral disinfectant and wipe dry to prevent mildew.

Regular inspection:

Check whether the screws are loose (especially adjustable parts).

Repair the paint loss to prevent metal rust or wood cracking.

Long-term storage: Avoid direct sunlight to prevent fading or deformation, and use cushions to separate when stacking.
