The COVID-19 pandemic changed the way we live, work, and interact with the world. One major lifestyle change has been the frequent use of hand sanitisers to prevent the spread of germs. While hand sanitisers are excellent for keeping your hands clean and reducing the risk of infection, there’s an often-overlooked side effect: hand sanitisers can damage your car’s interior.
Yes, it may sound surprising, but the chemicals found in hand sanitisers, along with some sun creams and other products, can cause premature wear and tear to your car’s interior, including leather seats, plastics, and dashboards. In this guide, we’ll discuss why hand sanitisers can harm your car, the science behind it, and how to prevent damage while keeping your hands safe and clean.
Why Hand Sanitisers Can Be Harmful to Cars
Hand sanitisers typically contain ethanol (alcohol) as the main active ingredient. Ethanol is great for killing germs on your hands, but it’s a potent solvent. When ethanol comes into contact with certain materials commonly used in car interiors—like leather, vinyl, and plastic—it can cause chemical reactions that gradually degrade these surfaces.

While a single incident may not create noticeable damage, repeated exposure over months and years can prematurely age your car’s interior, leaving it faded, brittle, and worn out.
Ford engineers have publicly warned about this risk. Mark Montgomery, Senior Materials Engineer at Ford’s Material Technology Centre, explained:
“From hand sanitisers to sun lotions to insect repellent, consumer trends are constantly changing, and new products are coming onto the market all the time. Even the most innocuous seeming product can cause problems when they come into contact with surfaces hundreds and even thousands of times a year.”
Which Car Materials Are Most Vulnerable?
Different materials in your car react differently to chemicals. Here’s a breakdown of the materials most affected by hand sanitisers:
Leather Seats – Ethanol can strip away natural oils from leather, causing it to dry out, crack, and fade. Leather conditioners help, but frequent exposure to hand sanitisers may still cause long-term damage.
Vinyl and Synthetic Leather – While more resistant than natural leather, vinyl can still discolor or weaken after repeated contact with alcohol-based products.
Plastic and Dashboard Surfaces – Prolonged exposure to ethanol can dull plastic surfaces and make them brittle. Harsh chemicals in some sunscreens and lotions can also leave stains or sticky residue.
Wooden Trim and Laminates – Certain chemical reactions can erode protective coatings, leading to discoloration or peeling.
Common Scenarios Where Damage Can Happen
Many car owners don’t realize how easily hand sanitisers can touch their interiors. Common situations include:
Using hand sanitiser before or after opening car doors.
Accidentally brushing sanitizer-covered hands on leather seats or plastic handles.
Spilling hand sanitiser while applying it inside the vehicle.
Wearing sun cream or insect repellent that comes into contact with interior surfaces.
Even small, repeated exposures can add up and reduce the lifespan of your car’s interior.
How to Protect Your Car While Using Hand Sanitisers
It’s important to remember that protecting yourself from germs is more important than worrying about minor car wear. However, you can take precautions to minimize the risk of damage:
1. Wash or Dry Hands Before Touching Your Car
Whenever possible, wash your hands with soap and water and dry them thoroughly before entering your car. This reduces the chances of transferring chemicals to leather or plastic surfaces.
2. Use Gloves
If you frequently need to sanitize your hands while driving, consider wearing thin driving gloves. This creates a barrier between your hands and the car surfaces.
3. Seat Covers
Using removable seat covers on leather or fabric seats can protect the original upholstery from chemical exposure. Seat covers are easy to clean and replace.
4. Wipe Surfaces Regularly
Keep a microfiber cloth handy to wipe down seats, armrests, steering wheels, and other frequently touched areas. This removes any residue left behind by hand sanitiser or sun creams.
5. Use Interior Protectants
Leather conditioners and vinyl protectants create a protective barrier that helps prevent ethanol and other chemicals from penetrating surfaces. Apply them monthly for best results.
6. Avoid Spraying Hand Sanitiser Directly on Surfaces
Never spray hand sanitiser on the dashboard, steering wheel, or seats. Always apply it to your hands first, let it dry, and then handle your car.
Additional Tips for Interior Care During the Pandemic
Besides protecting against hand sanitisers, you should also:
Clean your car frequently using mild interior cleaners safe for leather and plastic.
Ventilate your car to reduce moisture and prevent buildup of chemical residues.
Avoid prolonged exposure to direct sunlight, as UV rays can compound chemical damage.
Use sunshades on windshields to protect dashboards and plastic surfaces.
Conclusion
While hand sanitisers are essential for hygiene, they can pose a hidden risk to your car’s interior if used carelessly. Ethanol and other chemicals in sanitizers can react with leather, plastic, and other materials, causing fading, cracking, and premature wear.
The good news is that with simple precautions, you can keep your car safe while staying protected from germs. By washing hands, using gloves or seat covers, wiping surfaces, and applying protective conditioners, you can maintain both your health and the longevity of your vehicle interior.
Remember, your health always comes first, so don’t avoid using sanitiser. Just take a few extra steps to protect your car while staying safe.
