All Purpose Cleaners can be used to clean, well, virtually anythingâ€¦ upholstery and headlining inside the cabin, engine bays and wheel arches outside the car. They're like a strong shampoo, removing stains, grime and grease from soft and hard surfaces â€“ whilst rinsing out with water and leaving no residue behind. Total Wipe Out is a colourless solution, so it can be used on light coloured carpets and fabrics without staining. This concentrate makes ten times the amount of ready-to-go APC solution, although it may work at weaker concentrations (1:20, 1:40 etc). It is also foam lance compatible at a 1:10 concentration. And you can always use it neat if you come across really heavy contamination.
