I have an Italian espresso coffee maker that has collected a lot of oily stuff inside the upper container (where the coffee is collected). Someone had told me never to wash it, now I have my doubts. Any advice? I do not know the maker of the thing. Many thanks for taking the time to reply.

That oily buildup is certainly from the coffee. I would wash this pot on a regular basis. If you use it several times a day, maybe a rinse between uses would be sufficient, and a thorough washing once a day. I think the whole "not washing the coffee pot " idea is a very out dated one.
