I'm a bit surprised by this but my White silestone worktops seem to be staining when a coffee ring is left there for a few days - I thought this stuff was stain proof but on googling it seems that loads of people have had similar problems - the stain is subtle but I can stil see it. No more slack housekeeping for me!
Anyone else experience similar? Apparently silestone refuse to do anything under warranty because they only suggest surface is stain resistant not stain proof!
