Removing list elements in x by list y

I have simple question. Given two lists x = {u, v, w, w, d}; y = {u, d}; I wish to "subtract" y from x, i.e. remove exactly the elements in x which belong to y giving x "-" y = {v,w,w} Complement[] gives instead {v,w}. Note that we are talking about lists rather than sets. I'm sure there is a simple standard command, but I can't find it. Can you? Regards, Wolfgang
