Moulded plastic decoration on the glass, Has anyone come across this, I should have taken a photograph of it. all I can say is it was some sort of plastic moulding that sat up from the class and seem to be stuck to the glass starting from the corner if my memory serves me right it was something like a musical note shape. what is the best way to deal with this sort of thing it's on the ground floor. Got a feeling it's going to trap a load of dirt behind it.. The double glazing itself looked quite old. This is the first clean and the client is going to be out I may be tempted just to do it and see if it's streaks then microfibre cloth it.
