A car sunshade is a protective accessory designed to block sunlight from entering a vehicle. It is typically made of reflective materials that help reduce heat buildup inside the car, keeping the interior cooler and more comfortable. Sunshades come in various sizes and styles, including foldable and retractable options, making them easy to store when not in use. Using a car sunshade can also help protect the vehicle's interior from sun damage. Prolonged exposure to sunlight can fade upholstery and damage dashboard materials. By using a sunshade, drivers can maintain their car's appearance and extend the life of its interior components.
