I have used similar before, and yes, can be a nightmare to remove without 'swirl' marks.
Try using a new microfibre cloth, can get them all over the place now for £1+ and remove as much as possible.
Newspaper can be a good way to finish off, but usually I give the area a quick wipe with the leather, and may need a couple of rinses in between, but keep it as dry as possible. It may remove a small ammount of the glass product, but should not make any difference in performance.
