If the weather means your car is hotter than the seventh circle of hell this summer – you might be interested in this DIY top tip from an Arizona driver and content creator to help you stay cool.
The simple hack from ilovemegapixels went viral, amassing over 254,500 views on TikTok.
It’s cheap and easy to DIY using just aluminium foil to lower the car’s temperature.
The best part? People who’ve tried it say that it really works.

While leaving windows open – even slightly – to vent heat in summer can help, it may increase the possibility of theft or break-ins.
This TikToker seems to have a solution to help you stay cool.
In the video, he pulled open the car’s sunroof to reveal that he’d placed a sheet of aluminum foil or reflective sunshade under his car’s sunroof. Why? To block sunlight.
“Little tip for you,” he simply said before closing it.
That might seem counterintuitive, as aluminium is commonly associated with keeping food warm. But it turns out that he could be onto something.
The reflective surface of the foil reflects sunlight. And as result, it reduces heat buildup inside the car, especially through the glass of a sunroof.
Plus, it’s nowhere near as bulky or indiscreet as a windshield shade or foam insulation.
In fact, when another driver gave it a go, he reported a significant temperature drop of up to 30°F in the interior roof area using an infrared thermometer.
It might have been useful when a video emerged of cars in China becoming ‘pregnant’ in a heatwave.
While some solutions, like tinted windows or an entire roofless Lambo, are more cost-intensive, this hack is cheap, using materials like aluminum foil, home insulation, or heat-reflective mats.
Easy to cut and slot into your sunroof area without tools or permanent modifications – it’s doable even for the most DIY-averse driver.

However, it has nothing on these artists who turned unsuspecting cars into DIY masterpieces or this one who turned his couch into a car.
If your home is heating up too, you can also use it for home windows to reflect sunlight and reduce indoor heat – perfect for the TikToker’s home state of Arizona.
While some comments raised concerns about potential glass damage, tempered automotive glass is designed to handle heat.
The majority of commenters were delighted at the prospect of being able to stay cool in the heat this summer.
“I live in Texas! I will try ANYTHING!!!!!!!!” one said.
“Thank you! From an Arizonian,” another commented.
“Much appreciated – I’ll try that,” said a third.

All Supercar Blondie contributors undergo editorial review and fact-checking to ensure accuracy and authority in automotive journalism. After gaining her BA Hons in French and English at the University of Nottingham, Amelia embarked on a vocational diploma from the National Council for the Training of Journalists (NCTJ). This led to numerous opportunities, from interning at Vogue to being on the small team that launched Women’s Health magazine in the UK, which was named the PPA Consumer magazine of the year for three years running. As Health, Beauty and Fitness editor, Amelia personally received a Johnson & Johnson Award and was shortlisted for both PPA and BSME titles. Since then, Amelia has created content for numerous titles and brands, including the Telegraph, 111 Skin, Waitrose, Red magazine, Stylist, and Elle, as well as being Head of Content at Vitality and Editor in Chief at INLondon magazine. “My superpower is translating technical jargon about the mechanical workings of a supercar into a relatable story you’ll want to share with your friends after you’ve read it.” After joining the SB Media family as a senior journalist in September of 2023, Amelia’s role has evolved to see her heading up the SEO output of the editorial team. From researching the most ‘Google-able’ key terms to producing evergreen content - it’s been a time of hard work, growth, and success for the editorial team and the Supercar Blondie website. “I like to think of myself as a ‘method journalist’. In other words: I live and breathe whatever I am writing about. When writing about fitness, I trained as a personal trainer, and as a beauty editor, I completed an ‘expert’ in scent diploma with the Fragrance Foundation. “During my tenure at Supercar Blondie, however, I did something I never thought possible: I passed my driving test at the age of 36. One day I’d love to train as a mechanic to better understand what happens under the hood, too. “My sweet spot is providing readers with a ‘takeaway’ (read: something new they didn’t know before) after reading every one of my stories. While I don’t claim to be an expert in the automotive world, I know the experts and bodies in the field to rely on to provide our readers with an informative and thought-provoking story every time they visit the site.”
