This product is a cleaning alternative to dangerous combustible solvent cleaners. Premium Blue dissolves grime and brake dust without damaging your chrome and alloy wheels and rims. It's a highly effective wheel cleaner that can also double up as a high quality degreaser to safely remove brake dust, oxidization, dirt oil and grime. Made from a unique and non hydrofluoric acid formula. This is a factory approved way to remove brake dust safely and effectively. The product can be diluted in the ratio 7:1 which means one bottle will be enough for 1 liter of alloy wheel cleaner. This can be used more concentrated for heavier deposits.
