What are the small white dots on the windshield?
3 Answers
Small white dots densely appearing on the car windshield could be paint spots or tree sap, which need to be cleaned. Here are the cleaning methods: 1. Tar remover: You can purchase and use a dedicated tar remover, or use paint thinner, commonly known as banana oil. Additionally, gasoline can also effectively remove paint stains—apply it with a towel and wipe. Alternatively, you can buy and use a clay bar, which can polish the glass when rubbed. 2. Polishing treatment: If the front windshield surface is blurry with stains, polishing can be performed. Polishing removes surface pores and stains, restoring the glass to its original clarity. If the front windshield has cracks, small cracks can be repaired using repair tools to fill the cracks with repair fluid. Once the repair fluid solidifies, it can conceal the damage, prevent further cracking, and restore the glass. However, larger cracks cannot be repaired and require glass replacement.
Recently, several small white spots appeared on my car's windshield. At first, I thought it was dust, but it couldn't be wiped off. After asking friends, I learned that these are mostly caused by water stains or lime deposits, especially after washing the car with hard water. Sometimes, dried bird droppings or tree sap can also leave spots. Although these spots are small, they can cause glare when driving in sunlight, affecting visibility and safety. I tried spraying diluted white vinegar on the spots, letting it sit for a few minutes, and then wiping it off with a soft cloth, which worked well. Professional glass cleaner is also effective, but never use hard objects to scrape, as this may scratch the glass. It's recommended to thoroughly rinse the windshield with clean water after washing the car to reduce residue. Regular cleaning can also prevent the spots from growing and affecting the appearance.
Finding small white spots on the windshield while driving should be taken seriously, as they may be caused by flying stones or attached contaminants. Having dealt with similar situations before, I know that failing to remove them promptly can corrode the glass surface. A higher number of spots can cause glare on rainy days, interfering with driving safety. Take immediate action: use a damp cloth dipped in lemon juice to gently wipe the affected areas, or purchase a specialized automotive cleaning spray to apply and wipe. For prevention, avoid parking under trees to prevent bird droppings and tree resin, and choose soft water areas for car washing. Make it a habit to check the condition of the glass; maintaining a clear view is key to safe driving. Don’t wait until the problem becomes severe to address it.
