Really like my windshield and I want to clean and protect it. They recommend their own cleaner, but near impossible to find in Canada ( and I don't want to pay $20.00 frt from USA). I had used Plexus for years with great results but Klock Werks were concerned about possible problems with the aerosol propellent? Has anyone used Plexus on their Klock Werks windshield? Or another cleaner ? Novus is readily available here. Apologies for another "cleaner" thread!
