Review on CLARKS Mens Shoda Sneaker Nubuck Men's Shoes for Fashion Sneakers by Nick Moo

It is very comfortable to walk on and has an excellent travel impregnation. Worn in Zurich and then in Vietnam and Cambodia in January 2020. My only downside was that all the dust was in Siem Reap and my attempt to remove it with a damp cloth resulted in the light blue color fading significantly. It doesn't look like the same shoes. Otherwise it is in good condition. Anyone know how to clean up this stuff to keep the color?
