Smateria net products can be hand washed and hung out on the clothes line to dry - this material is extremely durable. Smateria plastic products can be wiped with a wet cloth. Please remember that Smateria's smoto products are made using recycled motorcycle seats, it is the nature of theproducts that they will have a worn look as the materials they are made from have seen a million bottoms during their lifetime! A wet cloth or a wipe down with a mild cleaning product like spray & wipe will restore the black sheen on the fabric. The seats are washed carefully when they are received by Smateria but they are all different and are one of a kind so you will receive products made from fabric with different textures and wear.
