■ If the dirt cannot be washed by neutral detergent, the detergent containing
no organic solvent may be used.
■ Do not wash the leather with organic substances such as volatile oil, ethyl
alcohol, gasoline, or acid or alkaline solution, as they will cause color fading
of the leather.
■ Using a nylon brush or man-made fiber cloth will damage the good patterns
on the leather surface.
■ Dirty leather trims always produce mildew. Pay special attention to
avoiding greasy dirt and always keep the trims clean.
■ Long-time exposure to the sun will cause surface hardening or shrinking of
leather. Therefore, be sure to park the vehicle at a shady and cool place,
especially in summer.
■ Avoid placing any objects made of vinyl plastics or materials containing
wax on the trims in hot summer, because temperature inside the vehicle
rises up easily. Such objects will stick to leather in a high-temperature
environment.
■ Incorrect washing of leather trims will cause color fading or generate spots.
