The interior glass is exposed to different contaminants than the exterior, including oils from hands, dust from the cabin, and fumes from cleaning products. Using the right materials and techniques ensures a thorough and streak-free result. Below, we break down the best practices for DIY automotive glass cleaning, including product recommendations and step-by-step instructions.

Step-by-Step Cleaning Process

- Apply Cleaning Solution: Spray a small amount of glass cleaner onto a microfiber cloth, not directly on the glass, to avoid overspray.
