Professional Steering Wheel Restoration and Sanitisation Guide (Jan 2026)

Determine if your wheel is finished in top-grain leather, bonded leather, Alcantara (suede-like), or textured plastic/urethane. This is critical as Alcantara requires specific 'dry' cleaning methods, while leather requires pH-balanced moisture. Testing a small, inconspicuous area at the bottom of the wheel is mandatory to check for colour transfer.

Ensure the vehicle is parked in a shaded area and the cabin has cooled. Working on a steering wheel that has been sitting in 40°C heat will cause your cleaning chemicals to flash (evaporate) instantly, leading to chemical spotting and ineffective cleaning. Aim for a surface temperature below 30°C.

Use a vacuum with a soft brush attachment to remove loose red dust, sand, or salt crystals from the stitching and the gap between the airbag cover and the wheel rim. Removing these dry abrasives prevents them from scratching the surface once you introduce liquid cleaners.

If using a concentrated cleaner like Koch Chemie Pol Star, dilute it according to the soil level. For maintenance, 1:10 is sufficient. For heavy oil buildup (common on work utes), a 1:5 ratio may be required. Use distilled water to ensure no mineral interference in the chemical reaction.

Spray your chosen cleaner directly onto the horsehair brush, not the wheel itself. This prevents the liquid from running into sensitive electronics like the clock spring or steering wheel buttons. Apply enough product to dampen the bristles but not so much that it drips.

Work in small 10cm sections. Use light, circular motions with the horsehair brush. You should see the clear liquid turn into a greyish foam; this is the surfactant encapsulating the body oils and dirt. Spend extra time on the 10 o'clock and 2 o'clock positions where hand contact is highest.

Stitching is the most vulnerable part of the wheel. Use a soft detailing brush to gently agitate along the seam lines. In Australia, red dust often settles here and acts like sandpaper. Ensure the bristles reach deep into the thread grooves to lift trapped particles.

Before the foam dries, use a clean, dry microfibre cloth to 'wipe away' the lifted contaminants. Use a rolling motion with the cloth to pull the dirt away from the surface rather than scrubbing it back into the pores. The leather should start to look matte.

If the cloth comes away dark brown or black, repeat the agitation. For extremely stubborn grease, you may use a steam cleaner. Wrap a microfibre cloth around the steam nozzle and pass it quickly over the leather. The heat opens the pores, allowing the cloth to wick up deeply embedded oils.

For volume controls and cruise control buttons, use a slightly damp (with 1:10 IPA/water) soft-bristle brush. Ensure no liquid ingress occurs. Use a toothpick or a dedicated detailing 'grabber' to remove any wax or skin buildup from the crevices around the buttons.

Often forgotten, the rear of the wheel rim accumulates significant sweat. Rotate the wheel 180 degrees to access the back easily. Repeat the cleaning process used for the front, ensuring the entire circumference is treated.

Wipe the entire wheel down with a fresh microfibre dampened with distilled water. This removes any lingering surfactant (soap) residue which, if left behind, can attract more dirt and cause the leather to feel 'sticky' in high humidity.

Allow the wheel to air dry naturally for 10-15 minutes. Do not use a heat gun or hair dryer, as this can shrink the leather or cause it to become brittle. The surface must be completely dry before applying any protection.

Apply a pea-sized amount of UV-protectant or leather conditioner to a foam applicator pad. Wipe it evenly over the wheel. In the Australian sun, look for products with 'SPF' or high UV-blocking capabilities. This prevents the sun from bleaching the pigment out of the material.

After 5 minutes of 'dwell time' for the protectant, use a final clean microfibre to buff the wheel. This ensures a uniform matte finish and removes any excess product that could make the wheel slippery—a major safety hazard.
