The Auto Finesse Imperial Acid-Free wheel cleaner contains a powerful blend of cleaning agents and degreasers to separate the brake dust and road dirt from the wheels on contact. Its high-foaming formula makes light work of a heavy task, and will take your rims from shameful to sparkling in a matter of minutes. Its highly concentrated formula is economical, safe to use on all modern coated wheel finishes, and is gentle enough that it can even be used for cleaning tyres. Unlike the 5L product, it is not concentrated, and doesn't have to be diluted.
