I tried gummi-pflege myself several times without success. Michele fixed it in a single attempt with some silicon product.
Its not the rubber door seals themselves you need to be looking at, but the felt strip, on the very top edges of the seals. They rub on the painted surface of the door surrounds. If you get some silicon spray, spray some into a small container, then brush the silicone into the felt strips, you should have no more creaking. Also, polishing the door surrounds, where the felt strips rub against, is a good idea, regards, SIMON.
