The answer to how to maintain upholstery is to regularly clean and care for your upholstered furniture. This will help extend the life of your upholstery and keep it looking its best. Start by vacuuming the upholstery weekly using the hose attachment to remove dirt and dust. Every 6-12 months, deep clean the upholstery using a mild soap and water solution or a professional-grade upholstery cleaner. Always test the cleaner on a small, inconspicuous area first. Avoid using harsh chemicals or scrubbing too vigorously, as this can damage the fabric.
In between deep cleanings, spot clean spills and stains immediately using a clean, damp cloth. Blot the area gently, don't rub. If a stain persists, consult an upholstery cleaning professional. They have the right tools and techniques to safely and effectively clean your upholstery without causing damage.
