The West Village Collection straps are made from nubuck leather. Nubuck has a sanded surface which gives it a unique natural velvety finish. However, nubuck tends to stain more easily than normal leather. The nubuck already has a water repellent finish but it is still important to treat regularly. You can use a general nubuck water and dirt repellent spray to do this.
In case the strap gets stained, please use a special nubuck rubber gum or sandstone block to clean it. Carefully brush the stain out of the strap. Once the strap is clean, apply the water and dirt repellent spray for extra protection.
