2005 - 2014 Corvette: GM TechLink: Excessive Brake Dust on Wheels
Source: GM TechLink, Page 6, July 2014
The wheels on some 2010-2014 Camaro, 2005-2014 Corvette, and 2014 SS models may collect an excessive amount of brake dust. This is due to the high-performance brake pad material — one of the by-products of the pad material is black dust — and the large openings in the wheels between the spokes, which highlights the brake dust.
The brake dust is considered a normal characteristic. Refer to the Exterior Care section of the vehicle’s owner manual for cleaning instructions.
The vehicle may have either painted, aluminum, or chrome-plated wheels. It's recommended to keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied.
TIP: Chrome wheels and other chrome trim may be damaged if the vehicle is not washed after driving on roads that have been sprayed with magnesium, calcium or sodium chloride. These chlorides are used on roads for conditions such as ice and dust. Always wash the vehicle's chrome with soap and water after exposure.
The surface of these wheels is similar to the painted surface of the vehicle. Use only approved cleaners on aluminum or chrome plated wheels. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes.
Use chrome polish only on chrome-plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application. Do not use chrome polish on aluminum wheels.
Do not drive the vehicle through an automatic car wash that has silicone carbide tire cleaning brushes, which could damage the aluminum or chrome-plated wheels.
