Do white people get scum in their skin?

I am a brown guy (Indian)
Sometimes when I haven't showered in a while, on rubbing my skin I will get a little bit of scum or dirt (which is skin itself, dead skin cells probably)
I was curious if white people also got it or maybe its just a non-white problem?
It doesn't happen with dry skin, it happens with wet moisturized skin
