I just bought some Wenol chrome polish on a recommendation while at OKC (Thanks Steve O).
On first application (by hand and rather quick), it seems to work better than anything else I've tried on my spinner. I did concentrate on one small area for a second application and a little more elbow grease. It did, indeed, remove all the water spots and shined really well.

There is a blue tube and a red tube. I got both of them and haven't determined if one is better than the other yet. Both seem to work really well.
