I want to cry. Brand new caesarstone work tops in pure white are a joke..been in 36 hours and already stained with what seems to be water rings leaving grey smears...we left a wooden chopping board on the draining grooves and it has left a huge stain that we can't remove. What's the point of a work surface you can put anything on?! I wouldn't it recommend to anyone. So confused as I had read such great things. Just fuming. Anyone else have a problem?
