Wheel and Tyre Detailing: A Step-by-Step Guide

Wheels are the dirtiest part of any car and the first thing people notice. Brake dust bakes onto them at temperatures the rest of the car never sees, winter salt attacks them from November onwards, and a pair of tired wheels can make a clean car look neglected. This guide takes you through a proper wheel and tyre detail, from the first rinse to a coating that keeps them clean for up to two years.

Why wheels get so dirty

Every time you brake, the pads and discs shed fine particles of metal and friction material. Those particles are hot when they land, so they fuse onto the wheel surface rather than just sitting on it. Add road film, tar and, in a British winter, a steady coating of salt, and you have a layer that ordinary shampoo cannot shift.

Left long enough, that contamination pits the lacquer on alloy wheels and leads to corrosion, particularly on diamond-cut finishes. Hybrids and electric cars are not exempt either. Because regenerative braking means the discs are used less, they rust more, and that rust gets thrown onto the wheels as fine orange dust.

What you need

• A pH-neutral wheel cleaner for regular washing, such as Wheel Cleaner
• An iron fallout remover: Iron+ gel or Iron Hunter liquid
• Soft wheel brushes: one for the faces, a long barrel brush and a small detailing brush for the wheel nuts
• A separate bucket and mitt used only for wheels
• A dedicated microfibre for drying, such as Yellow Bahama
• A tyre dressing such as Quartz Tyre Dressing
• For long-term protection, a wheel coating such as Gravity
• Nitrile gloves

Keep your wheel kit completely separate from the kit you use on paint. Brushes and mitts that have been on wheels are full of metallic grit and will scratch bodywork.

Step 1: Start cool and rinse

Never clean hot wheels. After a drive, brakes and alloys can be hot enough to dry products instantly and leave stains, so give them time to cool and work in the shade.

Rinse each wheel thoroughly with a pressure washer or strong hose, including the barrel and the arch behind it. This removes loose grit and sand so you are not grinding it into the finish with a brush. Take your time around the wheel arches, where mud and salt collect.

Step 2: Clean with a pH-neutral wheel cleaner

For regular washing, Wheel Cleaner is all you need. Spray it onto the cool, wet wheel. It foams and the foam stays in place, which gives it time to break down fresh brake dust and road film. On lightly soiled wheels, you can often just rinse it off.

Because it is pH-neutral, it is safe on every wheel finish: painted, polished, anodised, satin, matte and diamond-cut, as well as on wheels that are already coated. It works on tyres and rubber mats too, and it smells of lemon sweets rather than chemicals.

Step 3: Agitate

Work the cleaner in with soft brushes. Use the face brush on the spokes, the barrel brush to reach behind them, and the small brush around the wheel nuts and valve. Rinse the brushes often so you are not dragging dirt from one wheel to the next.

Never use stiff household brushes or abrasive pads. They leave fine scratches that dull the finish, especially on gloss black and diamond-cut wheels.

Step 4: Remove bonded iron contamination

If the wheels still look grubby after cleaning, or feel rough to the touch, the dirt has bonded. That calls for an iron fallout remover, typically a few times a year and always before applying a coating.

Apply it to a cool, clean wheel and watch it work. As it reacts with iron particles it changes colour and appears to "bleed". Work to that reaction rather than a clock, and never let the product dry on the surface. Agitate stubborn areas gently, then rinse thoroughly.

Both Ultracoat iron removers are pH-neutral and safe on coatings, and neither carries the sulphur smell this type of product is known for. The choice comes down to consistency:

• Iron+ is a gel that clings to wheel faces, barrels and vertical panels, so it stays where you put it for a longer dwell. It turns deep purple and smells of marzipan.
• Iron Hunter is a liquid that sprays fast and evenly, better when you are decontaminating all four wheels and the paintwork too. It turns red and has a mint scent.

Step 5: Clean the tyres

Tyres collect old dressing, road grime and brown residue that stops a new dressing from bonding evenly. Spray Wheel Cleaner onto the sidewall and scrub with a stiffer brush. The foam will turn brown as the dirt lifts. Keep going until it stays white, then rinse.

A properly clean tyre looks matt and dark grey. That is the surface a dressing needs.

Step 6: Rinse and dry

Rinse everything from top to bottom, including the barrels and the tread, so no product is left behind. Then dry the wheels with a dedicated microfibre. Blow water out of the wheel nut holes and around the centre cap with compressed air or a blower if you have one, as trapped water runs out later and leaves streaks.

If you plan to coat the wheels, make sure they are completely dry and wipe them down with a panel wipe such as Finest Wipe first.

Step 7: Protect the wheels

This is the step that changes how your wheels behave for the next two years. Gravity, from the InteliGraph series, is a graphene-ceramic coating built specifically for brake heat, winter salt and aggressive wheel chemicals. Once it has cured, brake dust sits on top rather than baking in, and a rinse with Wheel Cleaner does what a scrubbing session used to.

Apply a small amount to the applicator, spread it in a cross-hatch pattern, leave it for around 30 seconds, then remove the excess with a clean microfibre and buff with a dry one. Leave the car for 24 hours to cure. If your wheels are satin, matt or anthracite, try a hidden area first and check it in daylight.

Gravity works on exhaust tips, brake calipers and unpainted exterior plastics too, and a 50 ml bottle covers the wheels on up to six cars, depending on wheel size and design. For the best result, take the wheels off and coat the inner barrels as well.

Step 8: Dress the tyres

A tyre dressing finishes the job and protects the rubber from drying out and UV. Quartz Tyre Dressing is silica-based, so it lasts for weeks rather than one wash, beads water and does not sling onto your paint on the first drive.

You choose the finish. Leave it in place for a deep, wet-look gloss, or wipe off the excess with a microfibre after a few minutes for the satin look that suits most modern cars. Apply it with the sponge applicator or spray it straight onto the tyre and spread.

How often to do it

• Every wash: Wheel Cleaner, brushes, rinse and dry.
• A few times a year, and always after winter: a full iron decontamination with Iron+ or Iron Hunter.
• Every few weeks: refresh the tyre dressing.
• Every two years: recoat with Gravity after a full decontamination.

Summary

Good wheel care comes down to using the right product for the job. A pH-neutral wheel cleaner handles everyday brake dust safely on any finish. An iron remover deals with the bonded contamination that washing leaves behind. A proper wheel coating keeps brake dust from sticking in the first place, and a silica dressing finishes the tyres. Keep your wheel tools separate, never work on hot wheels, and your wheels will look after the rest of the car's appearance for you.
