Non professional detailers may try a 50/50 blend of vinegar and water with some fine steel wool (00 or 000) for windows.
The following information is more hazardous. Contact your local professional automotive detailer for assistance.
If the spots are very bad, a light blend of sulfuric and hydrofluoric acid is the next step with the steel wool on windows and a soft rag on paint. Cooling the surfaces with water is very important and never let the acid dry on any surface during the application process. In extreme situations where the water spots have baked into the paint for an extended period of time, wet sanding may be required. This will remove spotting but will also dull the surface. Buffing the car with a compound will restore the shine. Always re-apply a coat of wax after these steps.
