water spots
If those do not work, you need to tape up all the trim and surrounding paint areas and hit it with #0000 steel wool and a 90/10 mix of water/car wash soap. Just be gentle and work it in the same manner as a clay bar. Allow it to do the work for you. Just be sure to not allow any little filing to fall on the paint, it will scratch.
Hope this helps.
This has gotten off some heavy water spot transfer from a bad roof in the garage I had my car at. Works like a charm.
IF its REALLY bad they do sell kits that you can "polish" the glass but thats VERY involved and cost much more then trying swirl x.
