Before cleaning your car, check the recommendations made in your owner's manual and on the labels of any products you use.

It is just as important to keep your car windows clean on the inside as it is on the outside. A film caused by smoke, fingerprints, condensation, and other pollutants can build up on the glass.

• While ammonia works well in the home, it can harm many car surfaces, including window tinting, vinyl, rubber, and leather, and can be hazardous to your health. Therefore, using an auto glass cleaner specially formulated to be ammonia-free is recommended.
• When tackling the windshield from the interior, sit in the passenger side to get unobstructed access.
• For best results, use a microfiber towel to obtain a streak-free shine and clean the glass out of direct sunlight, which can evaporate glass cleaners too quickly, leaving a streaky residue.




• Spray the cleaner directly on the towel or use a glass-cleaning wipe. This will help minimize overspray and dripping caused by the steep angle of the interior windshield.
• Use an up-and-down motion, which allows you to easily identify streaking.
• For the hard-to-reach curves of the windshield and the rear window, try wrapping the towel around the back of your hand. Be careful not to damage the defrost lines. A small brush like a toothbrush is helpful for reaching corners and trims that have accumulated dust and grease.
• Lower windows about an inch so that you can clean the top part of the glass.
• Some experts recommend using balled-up newspapers for drying, as they are lint-free and the ink has a polishing effect.
• After cleaning the glass, consider using an anti-fog treatment. Anti-fog treatments use hydrophilic polymers or pigments to flatten water droplets into non-scattering water films.
• Keep a package of glass cleaning wipes in your car for touch-ups, such as cleaning fogged-up windows or wiping off sticky handprints.
