My husband and I like to travel with the top down on our convertible. However, this usually leaves a greasy film on the inside of our windshield. Last night, after a day of top-down driving, we realized that the film was making it impossible to see clearly in the headlights of oncoming traffic. We pulled over at a gas station to wipe the window with a cloth, which actually made things worse. Remembering lemon essential oil’s ability to cut grease, I put a few drops on my palms and smeared the inside of the windshield with it. Rubbing with a cloth to remove the oil, we were thankful to see that the greasy film was gone, and it was safe for us to get back on the freeway.
