Removing Surface Dust: Regularly wipe the briefcase gently with a clean, soft, dry cloth to remove surface dust and dirt. This is the most fundamental and important step in daily maintenance, effectively preventing dust accumulation from damaging the briefcase's material.
Treating Stains:
Leather Briefcases: Use a specialized leather cleaner for stains. Spray the cleaner onto a clean, soft cloth and gently wipe the stained area. Afterward, wipe the area again with a cloth dampened with water to remove any residual cleaner, then dry it with a dry cloth.
Nylon or Canvas Briefcases: For briefcases made of these materials, use a mild detergent diluted with water and gently scrub the stained area with a soft-bristled brush. After scrubbing, rinse thoroughly with water and allow to air dry.
