A local glass company that I use for rock chips uses Sprayway. The owner, a neighbor, told me that they have tried all brands and this works best for them. Plus, they use Bounty paper towels to wipe with.
He said that they have tried all brands of paper towels as well and Bounty towels don't leave a 'waxy' residue behind.
All I know is that after he repaired a rock chip on my windshield and cleaned it, the view was crystal clear....in my eyes. Good enough for a glass company that's been in business a long time is good enough for me.
On another note, I remember seeing a Motor Week show on PBS years ago that Bon-Ami is good for polishing glass....at least that's what Ed Goss said.
