Papercord is a natural material and has no surface finish. Over time through exposure to daylight, it will gain a beautiful natural patina.
Clean using a solution of 1/4 dl white soapflakes in 1 litre of clean lukewarm water. Wipe the surface gently using a soft cloth or sponge wrung out in the solution and dry at room temperature.
It is important that the papercord is not drenched in the solution and that it is moistened evenly to avoid staining as the surface dries. Repeat the process if the cord is badly soiled. The spillage of liquids that will stain (such as red wine) should wiped away immediately and not left to stand on the surface .
