For best results, Gyeon Q²M LeatherCleaner Strong should be sprayed on to the supplied microfibre buffing towel and then wiped over the leather surfaces in straight lines using light to moderate pressure. Stubborn soiling may sometimes require a deeper clean using the supplied Gyeon Q²M LeatherBrush, again using light to moderate pressure. To finish off, wipe up any excess product with the supplied microfibre buffing towel and then leave the leather to dry fully before applying Gyeon Q² LeatherCoat. Gyeon Q² LeatherCoat should be applied in a warm dry place out of direct sunlight. To apply Gyeon Q² LeatherCoat, lightly wet the supplied Gyeon Q²M MF Applicator with product and wipe it in evenly, using light pressure and overlapping strokes. Once all of the leather surfaces are treated, leave them to dry naturally for a minimum of two hours before sitting in the car.
