Is there any particular way to wash flat black, or any flat colors? Heard flat paint is easier to damage, is that true?

I'm looking into getting flat black wheels, so it is definitely helpful to know how to clean the wheels before purchasing them. Also, threads like the one I'm about to show, made me curious to know to to keep flat colors clean. Thanks for any advice

the wheels are most likely clear coated... so should be the same as others

use a good quality car shampoo with a brush. if that doesnt get it, then move to a non-acid based wheel cleaner (p21s makes one for example)- if that doesnt get it, post back cause i dont want to put the dangerous stuff in a beginning thread!!
