Alloy cleaner question

Just did my new car detail yesterday. I'd bought quite a few new products but have so many leftovers previously bought, that it's getting ridiculous.



So, although not my preferred alloy cleaner of choice currently, I have a lot of wonder wheels to use up.



Anyone using this on 403M 19inch wheels and is it safe? Think I read somewhere these wheels are machined.



Don't want to do any damage! They're not curbed (yet)
