does anyone have a way to take care of a scratch in the windshield?

If it isn't too deep, you can go to a reputable auto glass shop and have them buff it out.

~One mans opinion / observations~

Removing water spots / light surface scratches:
·Use detailing clay to remove any `hard' surface granules
·Use water/distilled white vinegar or a 5:1 Isopropyl Alcohol solution (adjust ratio as required) or try equal parts distilled white vinegar, Isopropyl Alcohol and distilled water to dissolve the alkaline-based, surface/etched mineral water deposits.
·Use a clean spray bottle and a 100% cotton Microfiber cloth to apply the solution to the glass surfaces
·Wipe off any residue from glass and dry with a damp waffle weave towel
·If any `water spots' remain apply Distilled White Vinegar un-diluted to a 100% cotton micro fibre towel, using a medium/heavy pressure on glass surface.
·If this does not remove the `water spots' use Autoglym Car Glass PolishTM and #0000 or #000 steel wool, use straight line motions only (circular motions cause swirl marks)
·Or apply a quarter size amount of Autoglym Car Glass Polish TM (See note 1) to a damp foam pad attached to a Porter-Cable random orbital buffer using speed # 4.
·Apply to half of the windshield, polishing first in an up and down motion then in a left-to-right motion and then repeat on the other side
·Wipe off any residue from glass and dry with a damp waffle weave towel
·Inspect glass for clarity and smoothness and repeat if necessary.

For deeply etched water spots' or pits (caused by sand or road stones) 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.

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~
