Interiors at 80 degrees: leather, plastics and the slow bake
Cabin temperatures in a car parked in the UAE sun routinely pass 70–80 degrees, and the surfaces facing the glass get hotter. Leather is skin — tanned, but still collagen — and heat drives out its moisture and oils, leaving it stiff, faded and eventually cracked along the seat bolsters and the top of the dashboard. The steering wheel and driver's seat go first because heat damage compounds with abrasion and sweat, which is acidic and salty. Interior detailing here is therefore less about vacuuming and more about chemistry: proper cleaning to lift the salt and grime out of the grain, followed by a conditioner or protectant that replaces oils and adds UV inhibitors.
Two cautions from the failure-mode file. First, silicone-heavy dressings — the ones that leave a wet glossy shine — feel like protection but attract dust, can make steering wheels dangerously slick, and in the heat they outgas and contribute to the oily film on the inside of your windscreen. Matte-finish, water-based protectants are the professional choice. Second, perforated and ventilated seats, common in UAE-spec cars, cannot be soaked; a good detailer uses controlled moisture and extraction rather than flooding foam into the perforations where it sits and sours.
