You must be VERY careful with solvents because you will unavoidably get some on the bodywork... whether by atomization or just plain drips and splashes.
I use white vinegar full strength, works like magic. Pour a cup or 2 in a bowl and use a small terry cloth towel soaking wet with vinegar and wipe it anywhere there are spots, dissolves the waterspots almost instantly without harming paint. Rinse well with a hose when done & wash the car as you normally would. I'd hesitate using anything stronger. I used some full strength muriatic acid (hydrochloric acid, 35%) a few weeks ago to clean some stainless steel parts, worked well on the stainless but was pretty brutal on all the surrounding stuff it spilled on and totally dissolved some aluminum parts that accidently were nearby. Home Depot has muriatic acid in their garden section, comes 2 gallons for $7.59 in a cardboard box for shocking pools & hottubs. It's pretty harsh stuff, I can't recommend it but if you do use it, use propper precautions.

steel wool on glass does wonders... it sounds scary, but it won't scratch!
Brings a great shine to the windshield, I have a friend with a body shop and I saw him use some on my windshield.
I jumped and asked why, but he reassured me and he was correct.
