There is a type of suction cup-style aluminum foil insulated sun shade, which is simple and convenient to use. After unfolding the sun shade, attach it to the car window glass using the suction cups. Another type is the no-trace magnetic sticker, similar to commonly used double-sided tape, which has good adhesion and leaves no marks when removed. Simply fix the no-trace magnets on both sides, cut out the middle part of the sun shade fabric, and then pull the fabric apart on both sides to attach it. Below are detailed introductions about car sun shades: 1. Function: The primary function of car sun shades is to block sunlight, preventing light from entering the car in the shaded area, which helps reduce the heat inside the car to some extent. They also protect leather seats and the dashboard from UV damage and enhance privacy. 2. Classification: Car sun shades can be categorized into front, side, and rear shades based on their position.

I use a sunshade every time I park my car—it's crucial for protecting the interior. In summer, I unfold the aluminum foil sunshade with the silver-coated side facing outward to reflect sunlight and heat. I press it firmly against the inside of the windshield, tucking the edges into the gap above the glass to secure it. For suction cup models, simply attach them directly to the glass. In winter, I also use it to prevent frost and snow, making it easy to remove before starting the car in the morning and saving the hassle of scraping the windshield. The key is to choose one that fits the windshield perfectly for optimal shading, and don’t skimp on quality—cheap ones tend to become brittle and flake.

Using sunshades is actually quite simple, mainly divided into interior and exterior types. On scorching summer days, I opt for a foldable aluminum foil interior sunshade. After parking, I simply unfold it from the driver's seat with the foil side facing outward and tuck it behind the sun visor. For winter, a thicker frost/snow cover resembling a blanket is used externally over the windshield, secured at the corners with door clips. When choosing, don't just focus on cute patterns—prioritize even foil coating distribution, thicker materials for durability, and edges preferably with magnetic strips or soft rubber seals for better insulation.

As someone who drives long-term in the south, a sunshade is my summer essential. Using it is a three-step process: after parking, unfold the sunshade with the silver reflective side facing outward; gently press it along the inner edge of the windshield; finally, tuck the top part into the glass gap. The suction cup version is even simpler—just press it onto the glass like an inspection sticker. Key reminder: when parking, try to avoid facing the car westward to minimize sun exposure, and combining this with the sunshade can lower the temperature by 15 degrees. Even for quick shopping trips, don’t skip it—just five minutes can significantly reduce steering wheel heat.
