I recently tried Zymol leather cleaner on my M sport red leather seats. However, since then, the base of the passenger seat seems to have "stiffened" up slightly and the leather doesn't seem quite as soft as before. Is this because I used this cleaner without using a conditioner or some kind of care liquid afterward? To make matters worse, near to a seam on the drivers seat, the leather has cracked ever so slightly - this is only visable close up so not the end of the world, but I really want to condition them or protect them in some way.
