What is the recommended cleaning agent for preparing any pinchweld surface?

The recommended cleaning agent for preparing any pinchweld surface is glass cleaner. Using glass cleaner is effective because it helps to remove dirt, dust, oils, and other residues that could interfere with the bonding of adhesive materials used in windshield installation. Glass cleaners are specially formulated for the surface properties of glass and often contain agents that do not leave streaks or residues, ensuring a clean and smooth surface for optimal adhesion.

In contrast, while soap and water can clean surfaces, they may leave behind residues if not thoroughly rinsed and dried, which could compromise the adhesive bond. Acetone and alcohol are effective solvents for some applications, but they can be harsh and potentially damage some surfaces or seals. Therefore, glass cleaner is the most suitable choice for preparing pinchweld surfaces in the context of windshield installation.
