I have been using Quick Detailers and Waterless Car Wash sprays to clean my vehicles for years.  Indeed, my two cars have had a minimal number of traditional car washings with water and bucket because I use these products so often.Therefore, I was extremely excited to try a waterless wash product that I had not yet tried, Griot's Garage Spray On Car Wash Kit.  A 32-ounce bottle of the waterless wash and and three microfiber clothes are included in a beautifully printed box.First reaction, it was fun to receive an entire kit with everything you need to get started.  If you have caked on dirt, mud, tar, etc. you probably want to stick with a traditional wash.  However, if you're like me, most of the time, it's simply dust on the car, so a product like this can work great.I immediately went to remove the tags that came on the towels.  Tags can potentially scratch the paint's finish.  While the towels seemed of high quality, the tags did not cleanly rip from the towel.  Therefore, I had to constantly make sure I was not using the portion of the towel where the tag was torn off.  The towels also seemed to become concentrated with the spray on wash quickly, but if it had not been for the tag issue, I would have liked them more or less.  They are approximately 12 inches by 12 inches.  I quite like Meguiar's Supreme Shine towels as the tags remove cleanly and they are a great 16 by 12 inch size.Second, the wash product itself was great.  It cleaned the dust on my vehicles nicely.  The spray nozzle was another slight weakness though.  There isn't a fine enough setting, so you get a lot of overspray.  This is not a problem when you're washing the entire vehicle with the product, but say you wanted to just "touch up" the front bumper or hood, you might find you get overspray on nearby panels and have to clean them too.However, the product left a great slick, smooth, and glossy shine.  It not only cleans, but adds a bit of slickness and shine too.Overall, Griot's Spray on Car Wash is up there with other quality quick detailers and spray on car washes that I have tried.  However, considering its price and slight flaws, I will be sticking with my Meguiar's products most of the time.  Meguiar's Ultimate Wash & Wax Anywhere is a superb product combined with Meguiar's Supreme Shine Microfiber towels.  I find the Meguiar's offering is overall probably a better experience at a lower cost.  Griot's offering is a good product, but for the price, it should be refined.
