Washed the FF yesterday.

Used Bilt Hamber Auto Wheel Cleaner for the first time.

Brilliant!

Spray it on ... leave for 10 mins ... agitate with a brush if you need to (I didn't even try) ... rinse off ...

... sparkling wheels!

As it works all the brake dust goes red. And your wheel looks like it's in a horror film

Highly recommended product. What do I put here then?

Sounds very like Dragons Breath alloy cleaner. It’s not the brake dust that goes red, it’s all the metallic bits that react with the fluid and make the wheels bleed.
I’ve used it a few times with positive results  Got - 2017 SDV8 Autobiography in Loire Blue
Had- 2008 TDV8 Vogue SE in Java black
Had - 2007 S/C in Stornoway Grey

And the same as iron-X.
Excellent stuff.

You can even use it on paintwork if you need to, to get brake dust off lower doors etc (eg after track days - not that a FFRR does one very often ) Too many toys, not enough time

2011 4.4 TDV8 AB Black

Chemistry was never my strong point  What do I put here then?
