The only way to truly remove ferrous particles is with a dedicated iron remover like Iron X. Iron X opens up the paint’s pores to release iron particles and to neutralize the caustic compounds that have developed as a result of the particle. In one step, you can eliminate the cause and its effects. Put an immediate stop to paint damage before it’s too late. Iron X should not be used on chrome, bare metal parts, brake calipers, wheel balancing weights, or SMART paint repairs. Mask off these areas. Avoid letting Iron X dry on any surface. Iron X is a clear solution in the bottle but it turns purple when it comes into contact with sintered iron particles.
