My husband purchased this oven for me and I am very disappointed with the drip pan. It stained with burn on food marks the first time I used the oven. I soaked it for two hours in hot water and dish washing liquid to no results. Even used a non abrasive pad to scrub, still no results. The second time I used my oven I placed aluminum foil over the top and it helped some but still has some burn marks. I am using the correct time and temperature as per the book. Is this to be expected or did I just get a bad drip pan? Thank you, Sharon Bowyer 1939 Wilson Avenue St. Albans, W.v-25177--(3**) **7-8946
