Treating oil stains on car windows, especially during rainy days, requires specific methods to ensure visibility and safety. Here's a step-by-step guide:

Materials Needed:

• Glass cleaner or vinegar
• Baking soda
• Soft cloth or sponge
• Microfiber cloth
• Water
• Dish soap
• Rubbing alcohol
• Spray bottle

Step-by-Step Method:

1. Initial Cleaning:

   Spray ac or a mixture of water and vinegar (1:1 ratio) onto the window.    Wipe it down with a soft cloth or sponge to remove any loose dirt and debris.

2. Baking Soda Scrub:

   Make a paste using baking soda and a small amount of water.     Apply the paste to the oil-stained area and gently scrub with a soft cloth or sponge.      Rinse thoroughly with water.

3. Dish Soap Solution:

   Mix a few drops of dish soap with water in a spray bottle.     Spray the solution onto the window and scrub with a soft cloth or sponge.     Rinse with water and wipe dry with a microfiber cloth.

4. Rubbing Alcohol Treatment:

   Dampen a cloth with rubbing alcohol and gently wipe the oil-stained area.  This helps to break down and dissolve any remaining oil residues.   Wipe dry with a microfiber cloth.

5. Final Cleaning:

   Spray the window again with a glass cleaner or the vinegar-water mixture.  Wipe it down with a microfiber cloth to ensure no streaks are left behind.

Additional Tips:

Avoid Abrasive Materials: Do not use abrasive scrubbers or pads, as they can scratch the glass.

Rain Repellent Products: Consider using a rain repellent product on your windows to help prevent oil and other contaminants from sticking.

Regular Maintenance: Regularly clean your car windows to prevent the buildup of oil and other residues.

By following these steps, you can effectively remove oil stains from car windows, ensuring clear visibility even on rainy days.
