Many are actually excess clay from the chip edge of one, scraped onto the face of another -- and magic eraser helps remove it, but not very well. Scraping it off with the blunt edge of an x-acto blade often is necessary to remove it all.Are these just marks that can be removed with a Magic Eraser? Those aren't dented are they?
And yeah, if the rack check was intense or severe enough, the chip face and/or inlay surface can show a physical depression line(s), even after it's been cleaned up. And there is also sometimes one chip (or more) with a rounded edge in just one spot, where the chip was used to 'check the rack' for full barrels. It's a barbaric practice.
EDIT: i wa referring to rack check marks above.
I haven't experienced the stacking marks that @Tommy showed, although I have had racks -- not chips -- damaged by tight-fitting new chips where apparently the inlay material or adhesive (or possiblly excess machining fluid) attacked the inner ends if the acrylic rack barrels.
