A clean break

Firstly:
Avoid the use of acidic or alkaline cleaning agents as they can damage the wheels and rims.
Secondly:
Only use cleaning agents on wheels that have cooled down. If the tyres are warm, it may cause a reaction with the surface material which will damage its perfect finish.
To remove persistent dirt such as brake shoe residue, use a soft sponge with the cleaning agent to wipe it away. Do not use any other equipment such as brushes or steel wool as these will damage the wheel's surface.
Thirdly:
Avoid spraying any rim cleaning agents on the brake pads or system, and once you have finished cleaning, carry out a quick brake check to remove any possible residue.
Fourthly: When using cleaning agents, please make sure you wear protective gloves to safeguard your skin from any irritation.

Care and Cleaning Instructions

Due to the high temperatures of modern day road cars it is often useful to wash the wheels after any prolonged use where brake dust may sit or eat into the alloy. A similar procedure should be carried out during winter months where alloys have an increased risk of attracting grit and road salt.

Please also note that stone chips from any given road surface which penetrate the coating or a lacquered surface and subsequently oxidise around the wheel, or any part of the wheel is 'kerbed' or mistreated cannot be accepted for or any part of a factory warranty claim. This would be deemed general wear & tear.
 
Please be aware of the correct method to clean the wheel, use only this method.
DO use only mild soap and water to clean your wheels
DO wax your wheels on a regular basis using standard car wax
DO clean your wheels with a soft material such as a terry cloth towel
DO NOT use an abrasive cloth or cleaner
DO NOT use "aluminium wheel cleaners". Most are acid based and may destroy the finish of your wheels
DO NOT allow road salt to sit on your wheels. You should wash them as soon as possible
