Although I like the time-management angle, I would personally encourage other readers to stick with approved brake pads. Others on this list have reported creeping problems with brake fade and squealing with low-dust pads.
To me, having absolute confidence in my brakes being able to handle a panic stop without any problems is worth the extra effort of cleaning my wheels.
FWIW, the wheels on my car were neglected by the PO. I did take 2 or 3 hours getting them into shape. Now, it is literally a 10-minute (or less) proposition to KEEP them clean each week.
I recommend P21S gel wheel cleaner. Works wonders!
