The interiors of the cars are exposed to a multitude of external agents that cause them to deteriorate. Now in summer, the use of sunscreen increases a lot, which has been shown to have negative effects on some materials. To this we must add that in recent years the use of hand sanitizers has grown, some of which are harmful to cars. Luckily, some manufacturers like Ford are already taking it into account. The oval brand engineers are constantly testing all kinds of products on the materials they use in their interiors. It is made with the purpose that they maintain a good state with the passage of time that they age in the best possible way. And these products that are good for our health are not so good for the vehicle, as Ford has been able to verify during his continuous studies.
Sunscreens, especially those with the highest protection factor, contain high amounts of titanium oxide. That chemical compound can react with car plastics or with the natural oils of leather upholstery when it’s hot. On the other hand, insect repellent, also very much used now in summer, are composed of diethyl toluamide (DEET), which can also cause premature wear in some components, special mention for hand disinfectants (gel, foam or wipes), a product that is expected to grow by 60% in the next five years. Many of them have ethanol in their composition, in some cases in a percentage of up to 80%, which does not contribute positively to the maintenance of the vehicle. Ford continues to work for its interiors to survive these products and testing at extreme temperatures (from 74 ºC and ultraviolet light, to -30 ºC while being hit)
