Remove dust from the leather often, using a cloth or vacuum cleaner.
Otherwise, particles of dust and road grime chafe in pores and folds, and lead to increased wear and premature degradation of the leather surface.
To guard against discoloration, such as from clothing, provide leather care roughly every two months.
Clean light-colored leather more frequently because soiling on such surfaces is substantially more visible.
Use leather care products; otherwise, dirt and grease will gradually break down the protective layer of the leather surface.
Suitable care products are available from the service center.
