My father-in-law has done it. My friends have done it... They grab a big ole dollop of saddle soap, rub it all over their leather jacket, and treat saddle soap like leather polish. The problem is that saddle soap is an astringent. It has lye and other acids that will actually hurt your leather over time if you don't completely remove the saddle soap after application. In this video, I'll show you how to properly apply saddle soap and how to condition and protect your leather jacket so it can stand up to the elements, work, and play.
