An alternative that isn't an acid is Meguiars Non-Acid Wheel Cleaner. I use it 2:1 on my daily drivers (VW rear brake dust, ugh!) and 1:1 on nasty ones. It will harm uncoated aluminum wheels however. Both work great, some people don't like the acid. Either way there's some scrubbing that's gonna be required. On something like that there is no easy spray and rinse option...
The D143 Non-Acid version also works as a great tire cleaner.
At full-strength, the D143 is quite similar in performance to the D140, but requires more scrubbing on stubborn deposits.
With that said, I really doubt that the D143 is significantly safer than the D140. The D143 is a high-alkaline type product, which can be just as caustic.
However, D140 is significantly cheaper than D143.
Anyone who's having to use these types of products frequently on their personal cars, should really consider Opti-Coat for their wheels. It makes cleaning a lot easier and you will not have to resort to these cleaners on a regular basis.
Generally how much should someone expect to pay to have their wheels done in Opti-Coat?
Just do it yourself - a tube of the stuff runs between $55-$70 depending on where you get it.
Clean the wheels really well, degrease. Hand polish if necessary. Wipe down the areas to be coated with a strong IPA solution. Then use a foam applicator and apply it on. Wipe off any high spots after 5 min; if you miss any high spots, no one will ever see 'em on wheels...
