CARPRO IronX is a highly effective, non-acidic and pH-balanced metal plaque remover. “Using IronX saves you time and avoids the car clay cleaning process used in traditional car care regimes. This CARPRO IronX formula is safe and effective for use on all car surfaces. Chemical compounds and black particles (particles containing iron) in the air actually penetrate the paint/varnish and create corrosive compounds that burrow deep into the paint/varnish layers. It is a gradual process that is not obvious until it is too late. IronX contains unique chemical ingredients that effectively dissolve sintered iron to form a water-soluble iron complex.
