What do I do for an oven – can covering it in new silver foil be enough? (all the dishes I put in are Pesach ones?)
Clean the oven (and racks) thoroughly [of course this is easier with a ‘self cleaning oven’] and turn it to the highest setting for 50 minutes. Then you can use it on Pesach. No food can go directly on the racks, but Pesach utensils OK.
