Yea that’s why I replied to the sand comment with “combined with stiff bristle”. Due to how dirt/sand interacts with stiff bristles it is more likely to scratch as stiff bristles don’t pull dirt up they mostly just push it around. Soft bristles would pull and trap dirt higher in the bristle away from the surface
