I so often see cleaning advice like "use a soft microfiber cloth" but nobody ever bothers to mention that microfiber cloths are really good at getting hard bits like crumbs stuck into them and that if you reuse that cloth, it'll badly scratch up whatever you're trying to clean
@joepie91 true, we bought a bunch of quality ones that are machine washable (not all of them are) .
It'd have to check brand it was.
I've never had this problem since we bought these new ones
