Most of the stains were from pens, markers, body oils, and everyday office use. Over time office chairs collect a lot more dirt than people usually realize, especially on armrests and seat cushions.
Protective chair covers can definitely help extend the life of office furniture and reduce wear, but eventually deep professional cleaning is still needed to fully remove embedded soil and buildup from the fabric.
Regular upholstery cleaning not only helps the chairs look better, but can also help them last longer and keep the office feeling cleaner overall.
