Wait at least 24 hours after a windshield replacement
to wash the vehicle. Definitely avoid the car wash as their high-pressure jets can act on the yet-to-dry sealants used to replace the windshield. It is also possible for the cleaning agent used by the car wash to have an abrasive effect on the sealant. If you must, wash your windshield at home gently using a mild soap. Spray water softly on the glass. In the unfortunate circumstance that your windshield has been replaced incorrectly, the mistake will become evident during driving. A whooshing sound, wavy patterns on the glass or blurred vision while driving are signs to watch out for.
