In most cases steel and alloy wheels are either lacquered or painted. These coatings protect the metallic surface from corrosion and provide attractive finishes to automotive road wheels. As vehicles brake the dust generated from pads, discs and drums is at elevated temperatures, amongst this hot cloud are thousands of hot metallic particles, these bombard the wheels finish and effectively embed themselves on to the wheel. Once lodged these particles are extremely difficult to remove. Acid based alloy wheel cleaners attack these metal particles effectively, reducing its size - allowing the particles and dirt clinging to it to escape. Caustic alloy cleaners are less effective than acid ones on brake dust, but can attack organic coatings such as lacquers and paints on short exposure, they attack any organic matter accumulated around the embedded particles and produce a seemingly clean surface, however with continued use they will dull and diminish the coating, leaving a wheel surface that needs refinishing. The more effective and safe to use auto-wheel works in an entirely different way, and has proved itself by winning yearly independent tests conducted by the UK’s biggest selling automotive magazine! Most recently in 2017 when we were up against both powerful acid and alkaline cleaners. auto-wheel’s pH neutral formulation reacts with the oxidising surface of the metallic particles rendering it water soluble, the rapid removal of this microscopically rusted surface reduces the embedded particle size and releases it from the surface. Unlike acid based alloy wheel cleaners, this method is harmless to the wheel’s finish. The reaction is seen by a rapid colour change from clear to deep red. After a simple hose, rinse down or jetwash it leaves the wheel spotless.
