I believe that the Lemon type has a small amount of lemon oil in it. They used it on the brushed stainless elevators in my office building. It DOES leave a slightly oily surface which if not wiped off would likely make dust stick to it but the beauty is that it is so easily cleaned off again with a spritz onto a dusting rag and a quick wipe down. With a bit of practice I'll bet the whole frame could be "cleaned" this way in about a minute or less.
