Iron Melt is an fast acting, acid-free, pH balanced cleaner designed to dissolve ferrous (iron containing) particles and airborne chemical compounds that can penetrate paint surfaces creating corrosive compounds that penetrate deep into the paint's sub-layers. Claying or polishing only removes the particle from the surface of the paint, but not its effects, which will continue to spread beneath the surface. Iron Melt was developed as a method of removing paint contamination beyond what can be removed by washing or claying.
