Motorcycle windshields are commonly made of Plexiglas or polycarbonate plastic. These materials are a lightweight, affordable, shatter-resistant alternative to glass that requires special care. Although it is far safer than glass polycarbonate, it cannot be cleaned like glass or it will quickly dull and scratch. Motorcycle windshields are often over-cleaned or cleaned with the incorrect materials which make a windshield appear cloudy. Cleaning a Plexiglas or plastic motorcycle windshield with extra care will assure the windshield does not scratch or cloud prematurely.
Items you will need
Clean soft cloth or towel Mild dish soap
Wet the surface of the windshield with a wet cloth. If the windshield surface is covered with stuck on debris or bugs set the wet cloth over the windshield to soak the dirtiest regions. Alternatively, fill a clean spray bottle with tap water and spray the surface of the windshield.
Ring out the wet cloth in clean water and gently wipe the windshield. Avoid using pressure during the cleaning process and allow the water to remove the dirt as much as possible.
Rinse the cloth and repeat wiping the windshield until the visible debris is removed. Do not scrub the windshield as this could grind dirt into the Plexiglas and create scratches. If the debris cannot be removed with just water dilute a small amount of a mild dish detergent in a bucket of water and use this dilution for cleaning.
Douse the windshield several times with clean water from the cloth. Repeat this process until all dirt and soap are removed. For extremely dirty windshields change the rinse water several times to avoid re-introducing dirt onto the windshield.
Dry the windshield with a clean cloth. Begin the drying process only after all the visible dirt has been removed. Pat the windshield gently and do not use excessive pressure while drying the plexiglass.
