Dawn will not remove enough of theZaino to bother with, if any. The most commonly available thing to remove Z is denatured alcohol. Isopropyl alcohol (common rubbing alcohol) will remove it, but denatured is more pure and won't leave as much residue. Of course, always use caution when working with any kind of chemicals, use outside and away from any ignition sources (alcohol burns!). You can also get wax removers from body supply companies that will remove Zaino. But, as stated, if you are going to use any type of abrasive swirl remover or cleaner, it should remove any existing Zaino from your finish.
