Oxalic acid and detergent-based cleaner for removing embedded iron dust particles and surface rust contamination from vehicle paintwork. Targets the gritty texture and rust spotting that accumulates during vehicle transport and storage — dissolves and lifts iron fallout without compromising paint integrity. Dilute one part CI AutoBrite to two parts warm water; apply by sponge to wetted surface after initial pressure wash, keep wet until contamination is cleared, rinse thoroughly. For persistent particles, repeat with a nylon bristle brush for added mechanical action. Not for prolonged contact with anodized aluminum or stainless steel — avoid surface staining on sensitive trim components. Built for auto detailers, dealerships, transport hubs, and vehicle prep facilities where iron fallout removal is a standard step before final detailing and delivery.
