I recently became aware of a sort of unseen characteristic of OG Cherry double shot key caps, and it is that their smooth surface, along with the material they are made of, do not keep dirt as easily as other plastics and surfaces tend to do. For example, I had one copy of Matt's Skull Squadron that I used for a couple of weeks, the caps keep considerable amounts of dirt in their rough surface, even when they are ABS double shots. In a second dirt magnet place comes Granite, that tend also to get dirty, but it takes more time to accumulate it, maybe a couple of months, the third place comes for a PBT set in Cherry profile that I had that takes over three months to get very dirty. In all the cases I was in need to soaked them in water with soap for hours, and then gently scrub the dirt off. The Beige DS OG Cherry I am typing now, has been clean two times in three years, it is being used in the same conditions as the others, and it looks pristine.
