The inside of my Jeep Grand Cherokee is black leather.  As much as I love the black leather and the interior of my Jeep, dust might as well be neon and flashing with as well as it shows up on the surfaces.  I try to keep ahead of it, but over the winter, it was cold, and I got lazy.  By rights, before taking Griot's Garage 11259 Leather Care Spray Kit for a spin, I should have vacuumed the seats, dash, cupholders, inside panels of the doors- you know.  But it's still kind of nippy outside, and I was just lazy.Because it's been a little while since I cared for my car interior, and a little bit of grubbiness was also showing, along with the dust (I'd blame this on my toddler, but I'm messier than she is), I used the cleaner first, like the instructions say for especially soiled areas.  The bottle of cleaner in this kit is good-sized.  I used it liberally and also used the included microfiber cloths.  I have lots of microfiber cloths at home, and these are on par with the rest of my microfiber cloth collection, but I think you can't have too many of these cloths, since they get "borrowed" for other household chores, or wind up up at the garage.  The microfiber cloths clean well.  I was able to get into the crevices with just the cloth and my hand.  This cleaner works well on leather, plastic, and fabric.  It even isn't a tragedy if you accidentally get some on your windows.  It buffs right off windows, no streaks.  I probably could have gotten really particular and used a cotton swab to get into the really tight spaces, but I didn't take the time to do so today, and the Jeep still looks practically new inside!Like I said, it's been a little while since I've taken care of the inside of my car- pre-winter, we're talking.  So of COURSE I used the leather care spray in the smaller spritz bottle.  It looks really milky and viscous in the bottle, and the instructions say to spray it onto a microfiber first, and then apply it to the perfed leather, which I do have on my seats, so that's what I did.  On the areas that aren't perforated, though, I spritzed directly on the leather, and that was fine, too.  I wanted to make sure the dash area was really conditioned, so I gave the entire interior a once-over with the conditioner, and went back to give the dash a second helping.  The interior gleams now!As for the smell, the cleaner doesn't really have much of a smell, and that's fine.  The leather conditioner has a good smell- there used to be a store at the mall I frequented as a kid called Wilson's Leather.  When I'd walk by that store, it smelled like rich leather.  This leather conditioner smells just like that.I'm really happy with the way this kit performed on the interior of my car.Now, I also have a leather motorcycle jacket I've worn all winter.  I wipe the outside with a damp-dry cloth when I need to, but I figured the leather on it seems similar to the leather in my Jeep, and that jacket's been out in the elements all winter long, so I used the cleaner and conditioner on my leather jacket, and it worked great on it, too.  I know I could get a product made just for leather jackets, but the Griot's worked just fine on it, and I had the Griot's out, anyway.  And I think it's fun to find a two-fer use out of a product.I still have a lot of this product left, too.  As it gets warmer, there'll be no excuses for not keeping my Jeep's leather interior well-conditioned and well-taken-care of!
