I use spray glass cleaner (windex or whatever equivalent is in the house) with cheap paper towels. Soft ones don't work as well.

The problem space is the inside (not on Cobras, but regular vehicles). The outgassing of the plastic creates a nasty film that is really hard to get rid of. It always streaks. When I got my windshield replaced I got a can of a foamy spray stuff from the glass company and that works really well. I've also used a water/vinegar/denatured alcohol concoction that cuts through it too.
