Cleaning Lexan windshields needs the right approach to keep them clear and scratch free. The Best Lexan Windshield Cleaner helps lift grime, haze, and road film without harsh abrasion. Start by rinsing loose dirt, then apply the cleaner using a soft microfiber cloth. Work gently in straight passes. Avoid ammonia and strong solvents that can cloud the surface over time. After wiping, rinse thoroughly and dry with a clean cloth for streak free results. Regular cleaning improves visibility and helps protect the Lexan finish, especially after winter salt or heavy dust.
