BlackJack is Duel Autocare's solvent based tar and glue remover, used as a decontamination step after washing and before polishing, waxing or sealing. It dissolves road tar and adhesive residue chemically rather than through scrubbing, so it lifts away with a wipe once the 2 to 3 minute dwell has done its work. It is safe on clear-coated paintwork, glass and wheels, though plastic trim, rubber seals and headlight covers should be avoided, and extra care is needed on vintage or single-stage paint. It pairs well with an iron fallout remover and a clay bar to complete the decontamination stage, and comes supplied with a chemical-resistant trigger spray across 500ml, 1L and 5L sizes.
