There is a lot of choice Ultimate finish sell many different products and brands. It’s a bit like oil choice some use Mobil some use Castrol some use Millers, I have used many branded products I tend to have a mixture and mainly Maguires. Always striving for the best for the money.
I use car chem iron detox mostly as I got it cheap at £38 for 25 litres black Friday last year. Bilt Hamber is indeed the best fallout remover but very expensive. Another good one for me was P&S Brake Buster at 1:1. Great for cleaning the tyres too.
Car chems clean wheels is also good at a reasonable price. Make sure you check out the car chem black Friday sale. They usually do up to 70% off – I’ll put on a thread when I hear more.
If you have the forged alloys I’d recommend you get some wheel woolies. Best and safest wheel brush IMO.
