Toxin is Duel Autocare's ready-to-use gel iron fallout remover, designed to dissolve embedded iron particles and brake dust from paintwork, wheels and glass. It turns purple as it reacts, giving a visible sign of where contamination sits and when the job is done, with a dwell time of 3 to 5 minutes and a pH of 6 to 8. The maker lists it as safe on all paint colours, clear-coated wheels, glass and rubber seals, with a cranberry scent. It comes in 500ml, 1 litre and 5 litre sizes to suit a single car or a fuller detailing kit. It sits early in a decontamination routine, best paired with a wheel brush, a tar and glue remover and a clay bar before waxing or coating.
