• Ethanol-based hand sanitisers are an important tool in the battle to keep the COVID-19 at bay, but they can age your car’s interior prematurely
• The use of hand sanitiser during the COVID-19 pandemic has seen sales soar; markets like Italy saw sales increase by 18 times compared with the same period in 2019
• Ford helps ensure customers’ vehicles look great for longer by ensuring interiors can withstand these and other new challenges by testing materials in extreme conditions

Due to COVID-19 guidelines more people are cleaning their hands with sanitiser when they get back in vehicles after essential journeys. This is good for the owner’s health, but it could be bad for the interior. Chemicals like ethanol in hand sanitisers can react with surfaces, causing them to wear prematurely unless they are protected by special finishes.

Engineers at Ford have long been tasked with testing new products on materials used in the company’s vehicles. Based on the test results the chemical constitution of protective coatings can be reformulated to ensure vehicle interiors remain looking good no matter what they encounter. Testing also applies to storage accessories, sold through Ford Customer Service Division, such as boot liners and interior plastic covers.

“Hand sanitiser is a product we saw an increasing use of some years back so it’s been part of our testing for a long time now,” said Mark Montgomery, senior materials engineer at the Materials Technology Centre, Dunton Technical Centre, UK, for Ford of Europe. “Even the most innocuous seeming product can cause problems when they come into contact with surfaces, but things like hand sanitisers, sun lotion and insect repellent can be particularly damaging.”

Use of hand sanitisers has boomed since the outbreak of the COVID-19 pandemic, for example Italy saw up to an 18 times increase in hand sanitiser sales when comparing year-on-year weekly data. Some recent forecasts have suggest the global market for hand sanitisers will increase by almost two and a half times in 2020 compared to 2019.  

While hand sanitiser helps kill germs on the user’s hands, and Ford vehicle interiors can withstand their potential damaging effects, it doesn’t mean that the rest of the vehicle is free from germs, especially if shared with other people. When cleaning, avoid using products containing bleach or hydrogen peroxide, as well as ammonia-based products as these can damage anti-glare and anti-fingerprint coatings. Household disinfectant can be an effective way to eliminate the threat.

“Particular attention should be paid to frequently touched areas such as the steering wheel, handles, gear stick, any buttons or touch screens, wiper and turn signal stalks, armrests, and seat adjusters,” said Jenny Dodman, Ford of Britain’s chief medical officer. “Seatbelts should also be high on every driver’s cleanliness check list. The seatbelt sits across you and is likely to bear the brunt of any coughs and sneezes.”

The Ford teams in Dunton, UK, and Cologne, Germany, test material samples at temperatures that can in some cases reach 74°C – the temperature the inside of a car parked at the beach on a hot day might reach. In other tests they simulate extended exposure to the sun, with samples bombarded with ultra‑violet light for up to 1,152 hours (48 days).

They also test plastics for strength at temperatures as low as -30°C when they become most brittle, repeatedly bouncing a heavy rubber ball on them to ensure the plastic doesn’t crack.
