I will use their pressured water if it's to cold to break out my pressure washer (or i'm out of gas) to knock off the big stuff then into the garage for a WW or RW.
I had to experiment with it in a few different ways as I have quite a few different materials on my inside. For certain ones it works better to spray directly on the surface, some better on the towel. Some require just one pass for perfection, some I have to "work" a little more for that perfect look. At the end of the day I really like the scent as well as the very matte finish that it leaves and just slightly darker than before but it does behave differently based on the material.
when you go to trade in your model year 2007 with 115K miles and the guy asks you if it a 2012 or 2013 model and think you are kidding until you show him the registration and odometer..
This is absolutely correct, much cheaper to buy in gallons for products you use a lot of. I am actually considering getting a 5 gal of the DWC this time around....
I typically hose mine off to get the loose dust off, hit them with compressed air to dry, apply the cleaner, let sit for about 20 seconds, agitate, let sit a little longer to let it work, then rinse.
