Definitions

  • automotive wheel cleaners have historically been acidic or alkali in nature. These automotive wheel cleaners may remove brake dust but they also have the potential to damage a wheel, especially when a metal surface is uncoated or if a coating has been damaged and the metal has become exposed. Acidic wheel cleaners are extremely good at removing brake dust but can only be used on coated wheels. If there is any damage to a wheel coating, a wheel is uncoated, or a wheel is made from materials such as chrome, acidic cleaners cannot be used since acid promotes corrosion of metals. Additionally, acidic cleaners have to be applied carefully to avoid contact with tires, bodywork, and/or friction components.
  • US 2005/0197277 A1 discloses an automotive cleaning formulation adapted to be applied to a wheel surface, comprising a cleaning composition and a brake dust barrier composition, said cleaning composition comprising water, sodium lauryl sulfate, a modified polycarboxylate copolymer, tetrasodium ethylenediaminetetraacetate (EDTA), an ethoxylated alcohol nonionic surfactant, and a buffering agent.
