The short version
The key is an acid-free wheel cleaner: spray on, let it act (it turns red, that is the dissolved iron fallout), work over with the wheel brush, rinse off. Never on hot wheels or in the sun.
Brake dust is aggressive: fine metal abrasion that eats into the wheel if it stays too long. Regular cleaning protects the wheel and keeps it looking good. With the right product this is gentle, without attacking the coating.
How the wheels shine again
Let the wheels cool
Never work on hot wheels, the product dries on instantly and can leave stains. Work in the shade.
Rinse off loose dirt
Rinse loose dirt with water, that saves product and prevents scratches when brushing.
Spray on acid-free cleaner
Apply acid-free wheel cleaner generously and let it act briefly. The red colour shows the fallout being dissolved.
Work over with the wheel brush
Use a soft wheel brush into the spokes and the rim well, that loosens stubborn brake dust.
Rinse & dry
Rinse thoroughly with clear water and dry, so no water spots remain.
Sealing saves work
A wheel sealant after cleaning makes brake dust stick less, the next wash is easier. Use acid-based cleaners only in exceptional cases and never on sensitive or polished wheels.
