One concentrate, dialled to the job. A good all-purpose cleaner replaces half a shelf of single-use sprays — strong for the dirty work, gentle for delicate trim.
An APC is the most versatile cleaner in the kit: diluted heavy for engine bays, wheel arches and ground-in grime, light for door shuts, plastics and upholstery. What matters is chemistry that cleans hard without discolouring fabric or drying out trim. Labocosmetica DÙCTILE is Alcantara®-approved and uses cationic surfactants that leave fabric soft and fluffy, while OMNÌA 2.0 adds tested virucidal and bactericidal action for interiors.
Dilute to suit the surface and you've got one bottle for the whole car, inside and out.
