we have a new oven. I have only used it once to roast a chicken but the juices splatted everywhere ,onto the actuakl element. so now it smokes when turned on. I am pretty useless with these matters. How can i clean the element without damaging it. Im really looking for a natural -home remedy rather than the oven cleaning products. A freind suggested vinegar. any ideas. help would be much appreciated. need to use this oven again!
