Hi folks, I've got an Iwachu round grill pan which I've just brought out of retirement and am loving a lot. The problem is that after cooking fatty foods such as sausages on it, although I can remove any stuck on/burnt crud with a stiff brush and soaking if necessary, I'm having trouble getting rid of all the oil and fat in between the ridges. The only method I've found so far is to get a wad of paper towels and go along every nook and cranny, which is time consuming and a big waste of paper. I could use cloth, but they end up staining and the stains are impossible to wash or bleach out. Is there something I haven't thought of (I can be really stupid sometimes and miss the obvious)? Any tips, advice, bits or bobs?
