If it still looks new after years of intensive use, then it’s staynu. This revolutionary newly-developed technology makes skai® upholstery materials and artificial leather particularly resistant to soiling and easy to clean. A special coating seals the surface so that dirt particles don’t stick to the material, or if they do, can’t penetrate deep into the coating. Whether permanent markers, foodstuffs, cosmetics or even discoloration of jeans and shoe creams: With suitable cleaning agents even stubborn soiling can be completely removed from skai® surfaces with staynu technology.
