Re: New KM rust?
Have you tried wetting it a little, putting some baking powder on and getting after it with a brush? I bough a used KM and the only spots on it were some leftover burnt coal (or shisha) marks
What type of metal is the KM, while KM's don't normally rust (or so I have come to believe) it depends on the metal period, you can't make certain metals not rust. Also, water could have been left on during shipping. Are you sure it isn't a knock-off?
