Through experience on long rides, my windshield comes off with a couple of screws and goes into the bathtub at the motel to soak to remove bugs.

Poly is a little better but not much.

I do use a silicone based stuff given to me to clean my windshields. Looks like old school Armor All. Supposed to make stuff not stick to it.

Is there a hidden reason you are cracking windshields?

The windscreen frame is a soft aluminum, I believe, and quite flexible. Some of the screws used to attach or hold things together, I suspect but don't know with certainty, abrade against the edge of the glass producing a fracture point much like scribing a line on a glass pane with a glass cutting scribe. Sooner or later a bump in the road pushes the windshield against the offending fastener once to often and you have a cracked windshield.
