Lemon against limescale on your windshield — it's an old trick that just went viral all over again. Journalists at an Italian outlet decided to put it to the test, and it turns out there's real substance behind it. Citric acid genuinely is used in specialized products designed to strip mineral deposits off car glass.
But there's a catch. And it's not really the glass that takes the hit — it's everything around it. A professional citric-acid formula made for auto glass is fine on the glass itself. Rubber and plastic nearby are a different story: manufacturers explicitly warn against letting the product touch those materials. Glass with additional coatings comes with its own separate restrictions.
Experts recommend washing your car in the shade on a cool body, using products actually made for cars: on a hot surface, the liquid dries almost instantly and leaves spots, while household chemicals risk being too aggressive for protective coatings. Specialists favor dedicated glass cleaners over homemade mixes.
Tarantas News previously covered how to properly care for your car's body. If you do still want to use lemon, the rule is simple: dilute the juice heavily with water, only work on a cool car, and rinse the glass thoroughly afterward.
