A typical interior detail uses three or four specialist products: one for fabric, one for plastic, one for leather, one for the dashboard. That is three or four bottles of mostly water sitting in a cupboard, and three or four price tags. This is concentrate. One bottle, diluted to suit the job in front of you.
Strong for engrained carpet stains and grime on plastic wheel arches. Mid-strength for door cards, dashboards, kick panels and door shuts. Gentle for leather and headlinings. The chemistry stays the same. The water ratio is how you scale it.
Inside the car
Carpets and floor mats, fabric upholstery, leather seats (at light dilution), vinyl and rubber, plastic trim, dashboards, door cards, headlinings, gear sticks, steering wheels, seat belts.
Outside the car
Plastic wheel arches, door shuts, fuel cap surrounds, exterior trim, rubber seals, alloy backs. Anywhere a degreasing clean is needed beyond what a shampoo will lift.
Concentrated, so a bottle goes a long way
One litre of concentrate makes up to 33 full cleans. A 5 litre bottle is over 160 cleans,32p each. The 250ml entry size is still 8 jobs in a bottle, useful for trying it without committing to the larger bottle.
1:10for dashboards, door cards, plastic trim, general interior wipe-downs
1:20for leather, headlinings, sensitive surfaces, any coated exterior trim
Patch-test on a hidden area first if you are not sure how a surface will react.
Spray onto the cloth or brush, not directly onto the surface, to avoid overspray on screens and electronics.
Agitate with a microfibre cloth or an interior detailing brush.
Wipe clean with a separate dry microfibre.
Around ceramic coatings
Stay at the weaker 1:20 dilution on any exterior coated surface to avoid stripping protection. If in doubt, snow foam and shampoo the panel first and save APC for the spots that resist the gentler products.
