Honestly as far as wheel cleaners, CG diablo is awesome, I use it on every type of wheel, it performs better as a cleaner and is a lot cheaper, the gel consistency and awesome smell is a bonus too. For heavily soiled rim barrels, I go straight to IronX spray and even the paste. I have tried Uber cleaner by Wolfgang, sonax one and pinnacles wheel cleaner. As far as cost

roduct:usability ratio goes, Diablo is my favourite.
I don't like autoglym product because they are a rip off. I have a bit of the same beef with Swissvax, even though I use their products on a professional level. Majority of both companies products are generic cleaners but they charge an arm and a leg for them. For example I cannot justify paying $110 for a 16 ounce Swissvax shampoo that I know will not perform nearly as good as some of my CG shampoos. Same applies to autoglym, they are overpriced generic products.
