I like to clay bar the outside of the windshield, and ISO alcohol on the inside for the plastic vapors. The glass cleaner product doesn't really matter, I have good luck with the cheap concentrate stuff from home Depot. It's all about the clean towel. Also wax on the outside of the windshield is nice, the rain just rolls up. That and a little of the gummy fledge rubber conditioner on the wipers is great for the rain.

I clay the outside of my windshield as well. Typically every spring.
