Cleaning my Pastels

Ever had one of those paintings where your pastels just go crazy and your pastels get all mixed up and muddy? You just zone out being all creative and then you look down.... Oops - dirty pastels. You can no longer determine if it is blue or a red! Time to spring clean your pastels.....Here is how I do it. Using oat bran I fill a ziplock bag half full. In go the pastels. With a bit of a shake and shuffle for 30 seconds - hey presto! Clean pastels.
