How to remove stains off windows.

How do you remove like water spots off windows. Is there any professionals that will do it or any products. Like on my s13. The rear quarter windows where the 240sx emblem is etched in. The black area you can really notice the water spots. Is there anyway of removing this?

It's kinda like scouring powder, but less harsh.

Yes there are ways to remove the spots, both professionals and products. Before I got my '97 240sx, I had a 2000 Stratus, and it had lots of water spots (supposedly caused from acid rain, pollen, and other air pollutents). But anyways, I dropped my Stratus off at a guy's house that used to detail for dealerships. I picked my car up about 2 hours later, and all I could think was "daaaaamn that looks good". I had gotten 15 percent tint a few months before and after I had the spots removed it made it look a hell of a lot better and a lot cleaner. But anyways, I'm trying to find out what he used so I can do it myself and I don't have to pay him $100 or so to do it.
