When cared for properly, the Linear Steel Series is designed to last. Follow these simple rules to care for your design in the best possible way. Clean the chair with a damp cloth after use. If necessary, use a mild detergent or dish-washing liquid, not concentrated. Always wipe with a dry cloth afterward. To minimize the risk of stains and marks, liquids, grease, etc., should be removed immediately. Lacquered surfaces can get scratches and chips if hit by other hard objects.
