Leather interior is a fantastic option if the person can take care and also afford it. They come in a variety of colours, thicknesses and are extremely robust compared to the usual fabric seats that the majority of cars have nowadays.
If you were to spill a drink or sticky food onto the leather then all you would require is a damp cloth that has been soaked in hot soapy water and rub vigorously across the effected area. This should have all of the stain removed from the seat effortlessly.
However, regular maintenance of leather seats should be adopted because they can become crinkly if they aren’t looked after with due care. Leather cream will be your best best as this stops the leather from drying out, a common occurrence with leather after a number of years since the material has been purchased.
