Why do I always find new little scratchers in and on my paint?

Hey, I’m going crazy because now within a year, by now, I would have to notice the third time a nasty surprise to my beloved paint. Smaller scratches formations on three different body parts, the first thought I had was that my Fix40 wash glove was not 100% free of stones etc., but I don’t think anything. Really polish away the scratches didn’t let themselves either. lg
