Not had the Caddy long, one of the wheels has a really thick crust of brake dust or something, originally just thought the finish was knackered and needed a refurb. But on closer inspection it’s just s build up of baked on crap.
I’ve been using wonder wheels and a wheel brush, it’s painfully slow but it is coming off. Do you wonderful lot know of any other products or tips that will make lighter work of cleaning the wheel up?
You might have better luck with iron and fallout remover. Otherwise I’ve had success with things like wd40 or a tar remover but often it’s a bit of trial and error.
Gyeon Iron I've found to be the best fallout remover,
Spray on, leave for 30 mins and/or agitate with a brush, rinse off, repeat (a lot in your case)
Autosmart Red7 I've not tried, but can be bought by the gallon, so might be more economical.
I use iron reactor by sams detailing but you may be better taking the wheels off and steam cleaning them with a hot pressure washer.
I've heard of people using things like cillit bang etc, it's good to know the harsher the 'detergent' the shorter the time it should be on the wheel. The iron reactor I use shouldn't be on longer than 5 minutes or any coating on the wheel like clear coat etc will start getting damaged.
Somthing like some clothes detergent mixed with sugar (so you have a soft grit) may work well.
But I'm no cleaning expert by a long way.

Iron fallout would be my go to. I use either gtechniq or bilt hamber one.
However, if it as been baked in to much you may need to get them refurbished.
These products are great but not always miracle workers.
Depends what you want them to look like and what you deem acceptable to yourself.
