The Allure of #CarTok

The #CarTok community offers a plethora of content: from DIY maintenance tutorials and cleaning hacks to driving tips and insurance advice. The platform’s short-form videos make complex tasks seem simple and accessible.​

However, not all that glitters is gold. A study by Auto Trader revealed that 59% of car-related TikTok videos provide advice that could potentially cause long-term damage to vehicles. ​

When TikTok Tips Turn Troublesome

Some popular TikTok car hacks have been debunked by experts:​

  • Toothpaste for Headlight Restoration: While it might offer a temporary shine, toothpaste can be abrasive and damage the protective coating on headlights.​
  • Using Household Items for Cleaning: Videos suggesting the use of items like dish soap for car interiors can lead to residue buildup or damage to materials.​
  • Repairing Scratches: A viral TikTok hack claims that coconut oil can fix even deep scratches — but in reality, it doesn’t work.
  • DIY Repairs Without Proper Knowledge: Attempting complex repairs, like brake fixes or engine modifications, without proper training can be dangerous.​

Auto Trader’s research found that 81% of car cleaning videos and 90% of repair videos on TikTok were not recommended for the average driver. ​

The Bright Side: Helpful TikTok Car Tips

It’s not all bad news. Many TikTok creators, especially professionals, offer valuable advice:​

  • Routine Maintenance Reminders: Tips on checking oil levels, tire pressure, and brake pads can help drivers stay on top of their vehicle’s health.​
  • Driving Techniques: Videos demonstrating safe driving practices, like proper merging or parking techniques, are beneficial, especially for new drivers.​

According to Auto Trader, 72% of maintenance videos and 68% of driving tips on TikTok were found to be helpful. ​

Before You Try That “Genius” Car Hack, Watch for These Red Flags:

  • 🚩 Too Good to Be True
    If a hack promises miracle results with everyday items (like toothpaste or coconut oil), it’s likely unreliable — or even damaging.
  • 🚩 No Expert Credentials
    Check the creator’s bio. Are they qualified mechanics, engineers, or affiliated with a reputable automotive company? If not, be cautious.
  • 🚩 No Proper Tools or Safety Gear
    If someone is “fixing” major car components with kitchen tools and no gloves, goggles, or proper setup, skip it.
  • 🚩 Overly Dramatic Claims
    “Save €1,000 in 5 minutes!” or “The car companies don’t want you to know this!” — classic signs of misleading advice.
  • 🚩 No Before-and-After Proof
    A genuine tip usually shows clear, verifiable results. If the video cuts straight to “after” or uses flashy filters, it might be hiding poor outcomes.
  • 🚩 Encouragement to Skip Professional Help
    Good advice often includes a reminder to consult a mechanic when necessary. Be wary of hacks that suggest you can do complex repairs yourself with no training.
  • 🚩 One-Size-Fits-All Solutions
    Cars vary massively by make, model, and year. Hacks that claim to work for “every car ever made” are usually oversimplified or risky.

TikTok offers a wealth of car-related content, but it’s essential to approach it with a discerning eye. While some tips can be genuinely helpful, others might lead to costly repairs or safety hazards. Always prioritise your vehicle’s well-being by consulting professionals and trusted sources.​

Stay informed, drive safely, and remember not every viral hack is worth the risk.​
