There are PH neutral cleaners about, this is what I use after having bad experiences years ago with acid cleaners. Good wheel cleaners that I use are Angelwax Bilberry (buy the big bottle and dilute to the strength you need), Auto Finesse Imperial and for the not very dirty at all very soft approach Auto Finesse Wheel Soap Revolution. I also periodically use a Iron Remover to remove bad brake dust (again, there are good less abrasive ones out there) and Tar remover for black tar spots every so often. Do this and all you'll have to worry about is the stone chips.
