I have used Griot's Garage products for years - almost exclusively for my cars of course. But for some reason I had never used the Griot's Leather Care. I have several other leather cleaners/conditioners in my cabinets, so I suppose I just figured I'd wait until I was low before giving it a try.Well, I finally did give it a try - as part of the Leather Care Spray Kit. First, here's what the kit contains:- 32 oz. of Griot's Interior Cleaner- Griot's "Finest Sprayer" for the above (a very nice adjustable sprayer by the way)- 8 oz. Leather Care spray bottle (sprayer is included)- 4 microfiber towels (appoximately 12" square)I have had the Interior Cleaner in my inventory of Griot's products for some time, so I am familiar with using it - and it works very well. But I had never really used it much on leather (mostly on the plastic and vinyl interior parts). Seeing that it was part of this kit - and obviously intended to be used on leather - I gave it a try. Works great!!Using the Interior Cleaner, and the green microfiber towel, I chose a formidable test area: a ivory leather couch... that my dog lays on. It gets filthy! I mean right down into the grain of the leather filthy. I usually clean with gentle soap and water and lots of elbow grease... and even then it never seems quite as clean as I'd hoped. The Griot's Interior Cleaner made much shorter work of the dirt than my usual method. Between the Interior Cleaner and the micro fiber towel, it realy gets into the deep grain of the leather and pulls out the embedded dirt. I was fairly astonished. I got the couch cleaner than I am usually able to - in about 1/4 of the time!Next step - apply the Griot's Leather Care, to condition and treat the leather (and clean whatever dirt still remains). Also using the microfiber towel (either a clean towel, or clean section of same towel), applying the leather care and using a gentle but deep wiping motion - back and forth - until the 'wetness' is gone. Then a light buff with a dry section of towel, and you're done! The leather is left with a very clean fresh look, and the surface is well mosturized but not slick or greasy. Running your fingers over it gives no "icky" feel of excess cleaner or the greasy film that some leather conditioners leave behind.Another noteworthy comment about the Griot's Leather Care is that it is (to my nose anyway) almost odorless. Some leather care products have a very strong and unpleasant odor. Some are almost perfumey... but the Griot's Leather Care is a very neutral smell. I actually stuck my nose into the towel after cleaning with it, trying to get a better idea of the smell - and it was still difficult to do.All in all, this is a great kit for cleaning and conditioning leather of all types. In the car, or in the house. I would even be willing to try it on leather clothing, like a jacket. I have not done that yet, but if I do I will update with comments. I will tell you first hand that you can trust it with the "white shades" of leather. I have various shades of "white" in one of my cars, and on family room furniture. Both cleaned up great with the Griot's kit with no side effects at all.
