Have had the Posi-Quiet pads on for over 24 hrs now and the wheels look as clean as they did 24 hrs ago.
That is a first.

Great improvement!

Also I tried the new Meguiars Hot Rims All Wheel cleaner - probably the best wheel cleaner I have tried. I did lightly brush the rims and the grime "liquified" almost instantly.

Luckily I wont have to use it very often .....now
