Spray-On Wheel Cleaners

Cleaner Selection
Because today's wheels are available in a wide variety of materials and finishes, spray-on wheel cleaners are formulated to treat specific surfaces. For example, polished aluminum and clear-coated wheels have softer skins than chromed steel, mag, wire or even rough-cast-alloy wheels. In effect, an aggressive cleaner that can remove surface rust from chromed-plated rims (and often from bumpers too) can unfortunately etch a polished-aluminum wheel.


Most car-care companies offer two formulations of spray-on wheel cleaners. If in doubt about what your wheels are made of, play it safe and start with a product that's intended for polished aluminum and clearcoats. On the same note, household cleaners/degreasers can be too harsh for today's custom alloy wheels.

Wheel Cleaning
Regular cleaning is the key to keeping fancy wheels looking good as new. Spray-on cleaners set out to attack contaminants before they become permanent fixtures so don't expect miracles on long-neglected rims. (Rehabbing rusty and/or etched wheels falls into the polishing realm.)


Begin the process by parking the car in the shade. Then, hose off the wheels to remove any loose dirt. Make sure that the wheels are cool before applying the cleaner so it won't dry prematurely and cause spots.


Next, arm yourself with the proper cleaner for your wheel style. Spray it liberally onto the wheel and let the product dissolve the grime for about a minute or however long the manufacturer recommends. For wheels that have deep contours and cavities, consider using special wheel-detailing brushes, pads and sponges (available at most car-parts stores) to help loosen hidden dirt.
