Selden Blitz 5L is a highly concentrated acidic cleaner intended for use as a periodic solution for removing brake dust and stains from alloy wheels. Containing a high concentration of hydrochloric acid and with a pH of 1 this product rapidly restores the appearance of alloy wheels and contains surfactants to lift dirt and rust inhibitors to minimise the acid attack on base metals. Not suitable for use on magnesium alloy wheels of wheels that have been finished with a decorative anodised effect, this is an acidic product that should be used with caution.
