To clean the tires I use OXO scrub brush and a 50/50 mixture of Eiman Fabrik HI-Intensity/water. I wet the tire with a spray of water, spray on 50/50 mixture, I then scrub with OXO brush. I also have a 3 gallon bucket of water with a small amount(half capful) of Auto International C car wash shampoo to rinse my brush in and supply additional soap/lubrication to wash the tire with.
Now, that said, I don't scrub and scrub. I scrub medium pressure all the way around the tire. I then rinse off, and then clean the wheel with a seperate brush. (and no, I don't rinse the wheel brush in the tire brush bucket!)
Before applying Vinylex, I wipe the tire down with a soft cloth. Then apply Vinylex with Eagle One Tire swipes. I let the Vinylex sit on the tire for about 30 minutes to one hour while I vaccum the interior etc. This allows the dressing to sit on the tire for a while.
Before I drive off I wipe down the tire again with a soft cloth, and remove any excess dressing. If I don't like the "black" level, I re apply the Vinylex and wait another 30 minutes or final wipe.
My car is 11 months old, I have seen mild greying at times, but normally that is just due to the tire being dirty. Other than that, I have had no problems. (tires Goodyear Eagles)
I complete this process once per week.
Hope this helps
