Lexan windows, made from polycarbonate, require careful cleaning to maintain clarity and prevent scratches. This guide offers practical, step-by-step instructions using non-ammonia cleaners and soft tools to keep Lexan surfaces looking clear and new.
Quick Answer
Use a polycarbonate safe cleaner or a non-ammonia cleaner designed for Lexan, applied with a soft microfiber cloth or pad. Gently wipe in a circular motion, rinse with clean water, and dry with a microfiber towel to minimize streaks and scratches.
What You’ll Need

Before You Start
Prepare the area to prevent dust from resettling on the surface. Use soft, non-abrasive tools and avoid household cleaners containing ammonia, solvents, or abrasives that can cloud or scratch Lexan.
