There are a lot of opinions about how often you should condition leather seats . There is not really a correct answer to this question. It can vary depending on the exposure to the sun, how many people typically ride in the2010 Mazda B Series or if there are pets and kids in the vehicle. A good rule of thumb is every three months. If the 2010 Mazda B Series is frequently used or spends lots of time in the sun, every two months may be a better timetable. On the other hand, if the vehicle is used gently on an irregular basis, cleaning and conditioning every six months should be sufficient.
