Wheels are the dirtiest part of any car. Brake dust is hot, metallic and bonds to the surface; tyres collect road grime and layers of old dressing. Cleaned properly, they transform how the whole car looks — a spotless car with brown wheels still looks unfinished.
Rule one: wheels first
Always clean wheels before the paintwork. Wheel cleaning splashes abrasive brake dust around — do it after washing the body and you'll be re-contaminating clean panels. And keep dedicated wheel tools: whatever touches your wheels should never touch your paint.
Step 1: Rinse and apply wheel cleaner
Rinse each wheel and arch to knock off loose dirt, then apply your wheel cleaner and give it a few minutes to work. A dedicated cleaner will dissolve what water can't touch.
Step 2: Scrub the tyres
Tyres need proper agitation. A stiff tyre scrubbing brush digs into the sidewall texture and strips out browning and old dressing — you'll see the foam turn brown as it lifts. Scrub until the foam runs white; dressing applied over dirty rubber goes patchy within days.
Step 3: Work the wheel faces and barrels
For spokes, calipers and behind badges, a finger mitt gives you glove-like control in the gaps a brush skates over. For heavily soiled faces and inner barrels, a drill brush on low speed makes short work of baked-on brake dust — the smallest head fits between spokes.
Step 4: Arches, then rinse
Wheel arches hold more mud than anywhere on the car. Rinse them out — a strong fan pattern does most of the work — then rinse the whole wheel thoroughly before moving to the next corner. Work one wheel at a time so cleaner never dries on the surface.
Step 5: Dress the tyres
Once the tyre is clean and dry, apply dressing for that deep, satin-black finish. On a properly scrubbed tyre it absorbs evenly and lasts weeks rather than days.
Do this once properly, and weekly maintenance becomes a two-minute job per corner — exactly how we keep our regular maintenance valet customers' wheels looking new.
