Milsek leather cleaner and conditioner is strong enough to gently clean dirt and remove stubborn stains from your furniture that were caused by pets or spills by children and effective enough to condition as well. Milsek's natural orange leather cleaner and conditioner moisturizes leather and vinyl, which prevents drying and cracking. All that's left behind is the ultimate shine and fresh scent of mandarin orange. It will not build up because it does not contain wax or silicone.
