SONAX Wheel Cleaner full effect is a highly effective, acid-free and pH balanced rim and wheel cleaner that is safe for all wheels, including aluminum and alloys. This formulation is also effective and safe for use on painted wheels and will not deteriorate clear coats. SONAX Wheel Cleaner full effect is engineered specifically for wheels that accumulate high amounts of iron-rich brake dust, oil and rubber residue and other road dirt and grime. This SONAX signature product changes colors from bright green to deep red as it interacts with the brake dust, loosening it from the wheel. A imple rinse is the final task to restore your wheels to their optimum shine.
