1. Choose Quality Sunshades: Invest in high-quality sunshades that are designed to reflect UV rays. Look for those that fit your windshield and rear window properly to ensure maximum coverage.

2. Install Sunshades: Place the sunshades on your front and rear windows whenever you park your car. For added protection, you can also use side window sunshades. These shades reflect the sun’s rays, preventing the interior from heating up.

3. Use Reflective Sunshades: Opt for reflective sunshades that have a metallic coating. These are more effective at reflecting sunlight and keeping your car cooler compared to regular fabric sunshades.

4. Consider Custom-Fit Sunshades: For the best coverage, use custom-fit sunshades designed specifically for your car’s make and model. These provide the best fit and maximum sun protection.

5. Apply Window Tints: Tinting your car windows can significantly reduce the amount of heat and UV rays that enter your vehicle. Check your local regulations regarding the legal limits for window tints.

6. Select High-Quality Window Tints: Choose tints that offer high UV protection and heat rejection. Ceramic and carbon tints are known for their superior performance in blocking heat and UV rays without compromising visibility.

7. Professional Installation: Have your window tints installed by a professional to ensure they are applied correctly and evenly. Improper installation can lead to bubbling and peeling, reducing the effectiveness of the tint.

8. Use a Combination: For maximum cooling, use both sunshades and window tints together. Sunshades protect your car when it’s parked, while tints provide continuous protection from heat and UV rays even while driving.

9. Maintain Sunshades and Tints: Regularly clean your sunshades and window tints to keep them in good condition. Dust and grime can reduce their effectiveness over time.

10. Additional Accessories: Consider using additional cooling accessories like steering wheel covers and seat covers designed to reflect heat. These can complement the use of sunshades and tints for a cooler car interior.
