Alumax is a formulation of citric and hydrochloric acids and wetting agents designed to clean and brighten aluminium with the minimum effort for maximum effect. Alumax is ideal for the cleaning and restoration of fixtures and fittings such as window frames and doors. Alumax can be spray or brush applied at the dilution rate of 10-1 with water, treating a small area at a time. Rinse off with clean water to complete the process. N.B. do not use on anodised aluminium or stainless steel surfaces. Alumax may also be used to etch steelwork prior to painting.
