Unfortunately, glass treated with RainX will never again behave like untreated glass. Nothing removes this stuff. I`ve spoken with the manufacturer at length about this effect. They offer little help and seem genuinely unconcerned. Frankly I`m suprised the product has had the success it has.
Have you tried Naphtha (as in Zippo lighter fluid) ? I tried it on the advise of Ron K, and it seemed to remove the Rain-X completely (well the wipers stopped chattering, anyway)
