I have water spots etched into the windshield and glass from the sprinklers and i have found a few products and would like opinion on which product works and is the best. keep in mind i already used vinegar with distilled water and used elbow grease but their still there. Heres what i found:

Zaino Z-12 Clear view glass polish

Chemical guys spot remover

PC 7476 with white pad and poli seal

Thanks for you guys help!
