Chrome wheel cleaner vs all purpose?

Hey guys,
I know I should be using sonax or p21s but I haven't gotten around to ordering yet. I picked up some Meg's chrome wheel cleaner the other day and used it a couple of mins before a wash. I didn't agitate and it worked really well at removing brake dust. Much better than all purpose. Thing is, I don't have chrome wheels. I have painted (I think). Is there any harm in using this product? Should I toss it and grab one of the othe products above? Thx
