Oil film on a windscreen, often baked on by sunlight, can be removed with a dedicated cleaning process beyond a regular car wash. An abrasive cleaner specifically designed for automotive glass is the key.
Steps to Remove Oil Film:
-
Clean the Windscreen: Begin by washing the windscreen with regular car soap and water to remove loose dirt and debris. Rinse thoroughly and dry. This prepares the surface for the abrasive cleaner.
-
Apply Abrasive Cleaner: Select a dedicated automotive glass cleaner designed to remove oil film. These often come in the form of:
- Liquids: Apply the liquid cleaner to a microfiber cloth.
- Wipes: Use pre-moistened wipes specifically for this purpose.
-
Scrub the Windscreen: Using firm, even pressure, scrub the windscreen in a circular motion. Ensure you cover the entire surface, paying particular attention to areas with visible oil film.
-
Rinse Thoroughly: Rinse the windscreen completely with clean water to remove all traces of the cleaner. Any residue left behind can cause streaking or reduce visibility.
-
Dry the Windscreen: Use a clean, dry microfiber cloth to dry the windscreen thoroughly.
-
Inspect and Repeat (If Necessary): Check the windscreen for any remaining oil film. If necessary, repeat steps 2-5. Stubborn oil film may require multiple applications.
Types of Cleaners to Use:
- Glass Polishes: These often contain mild abrasives to remove bonded contaminants.
- Dedicated Oil Film Removers: Look for products specifically labeled for removing oil film from automotive glass.
Important Considerations:
- Avoid Harsh Abrasives: Do not use household cleaners or abrasive compounds that are not designed for glass. These can scratch or damage the windscreen.
- Microfiber Cloths: Always use clean microfiber cloths to avoid introducing new scratches.
- Consider a Clay Bar: For particularly stubborn oil film, a clay bar designed for automotive use can help remove embedded contaminants before using an abrasive cleaner. Use it after the initial wash but before the cleaner application.
By following these steps and using the appropriate products, you can effectively remove oil film from your windscreen and improve visibility.
