You bet your jerk it is!! :bow
Just for the sake of testing...I tried Four Star Ultimate Wheel Cleaner Gel and Spray & Rinse Wheel Cleaner on the two front wheels of our Sequoia which recently have attacked by dusty TRD pads. I know this probably won't be the fairest comparison since 4 Star's gel requires you to use sponge or whatever to wipe down the wheel during the process, so I gave PB slight handicap by not spraying cold water onto the wheels before applying PB's S&R.
Here you can see how bad both wheels were..
As you can see both wheels were at the same level of "dirtiness"
Right front before 4 Star

4 Star is still one of my favorite wheel cleaner, and since I did not do any wipe down during the process as instructed, I did not expect it to do as well as PB's S&R. Plus, PB's S&R is advertised only need to "Spray AND Rinse" I'm very impressed with the PB S&R, it took out just about 95% of the dust and curd on that wheel...while without wiping the wheel 4 Star took about 80% of the junk off the other wheel. But with my passed experience I know 4 Star should do just as well with some wiping...
I can't wait to get the PB's S&W.
Pretty excited about their products. Maybe sometime this week I will try out their new car wash I bought. I chose that over the Meguiar's Shampoo Plus from their Detailer's line. http://www.properautocare.com/meshpl1ga.html
It's almost 4 times more expensive, but I think it should perform just as well as other PB products.
