New leather should be treated with our COLOURLOCK Leather Shield within the first three years to protect it against traces of wear and abrasion, as well as discoloration from clothing (dye transfer). The driver's seat (entry bolsters of sports seats and high support cushions) usually begin showing typical signs of wear within the first three years. Leather Shield will prevent this. Treat the driver's seat every three months, the rest of the leather every six to twelve months. Additionally, steering wheels, armrests and shift knobs often suffer from hand sweat so avoid grease- or oil-based leather care. Instead these areas (except those that are old and dry) should be protected using COLOURLOCK Leather Shield. The amount is usually sufficient to treat a steering wheel, small parts or the most heavily strained entry bolsters several times. The Cleaner should only be applied to soiled areas.
