Hi, we're hoping someone can help offer us some advice as I've just come back from a few days away to a pumpkin related disaster. The pumpkins we had on our mantlepiece for a Halloween party on Thursday and then promptly forgot about when we went away, have rotted and seeped on to our hearth which is a black slate like material and have left white stains on it. Does anyone have any idea on how we might be able to get rid of the staining? Many thanks!
