I noticed my windsheild looks like it's been parked under a Maple tree when it gets moist. It was like this when I bought it so I don't know the source of this contamination. I have tried 0000-steel wool but it did not come off. Tar & Bug Remover don't work either. All suggestions welcome. Thanks.
 
I've seen this sort of thing on my Mom's Yukon. It is like there are areas where there is wax buildup or something on it. It is very noticable when it is raining. I wonder if wax stripper would help?
 
The stains appear without the wipers moving and only are visible when there is a morning dew. i thought the steel wool worked because until a few days ago I could not seee anything. I was headed to work at 5AM this past saturday and they all showed up because of the morning dew. The are white-ish in appearance and vary in size from very small to 3/16th of an inch, give or take.

~One manâ€â„¢s opinion / observations~



They may be etched spots that when â€Ëœfilledâ€â„¢ with moisture becomes visible

Removing etched (below surface) water spots from glass--- are caused by acid rain or industrial fallout causing a chemical reaction, if left for any length of time they will etch the paint film surface leaving a concave circular mark.



These can usually be removed using detailer's clay to remove any hardened surface deposits and then using Autoglym Car Glass PolishTM with #0000 synthetic steel wool or a random orbital buffer (speed # 4) and a cutting foam pad (LC orange or yellow) to level the surface.



Notes:

1.Do not use abrasive cleaner; glass polish or any grade synthetic steel wool on after market-tinted glass or you will probably scratch the surface.

2.For deeply etched water spots' in the glass surface, do not attempt to polish them out, consult an automotive glass vendor as glass used on later model cars is soft and thin (this may vary by manufacturer) due to weight / cost savings by vehicle manufactures and polishing could cause glass to crack.

3.Be cautious with polishes that contain abrasives like aluminium or cerium oxide as they have the potential to damage glass beyond repair.

4.Some windshields and mirrors have a tinted plastic coating or a blue tint that will scratch or be damaged, only polish or use synthetic wool on uncoated glass.



~Hope this helps~

What does alcohol do to enhance the clay work? And do I just apply it then let it dry before I use the clay?

No, apply alcohol as a solvent. Use it to clean the window. Then clay using a QD (quick detailer) or diluted car shampoo (either in a spray bottle or applied via a wash mitt or MF (micro fiber) towel) as a lubricate. Be aware that the alcohol may strip your wax or sealant if you get it on the paint. It will not harm the paint though. For alcohol we're talking about isophol not eythol. Although, there was a post here about someone using vodka to clean windows. :rolleyes:
