Logic
All Purpose Interior Cleaner
Size
Logic is our concentrated all-purpose interior cleaner. Its active foaming action lifts everyday grime and stains from most interior surfaces – plastics, trim, vinyl, fabric and upholstery – leaving a fresh, natural factory finish. Dilute it to suit the job, work it in with a brush, then wipe away with a microfibre cloth. One bottle handles the whole interior.

Why You'll Love It
Plastics, trim, vinyl, fabric seats and carpets — Logic handles most interior surfaces, so you're not juggling a different bottle for every job. Dilute it to suit and work your way around the cabin.
It foams as you work it in, lifting grime and stains up out of textured plastics and fabric where a simple wipe would just move dirt around.
Logic cleans without leaving a greasy or glossy residue, so surfaces come up looking like they did from the factory — clean and matte, not artificially shiny.
It's concentrated, so a 500ml bottle makes up to five litres of ready-to-use cleaner. Dilute right down for everyday jobs and a bottle lasts a very long time.
What Does Logic Actually Do?
A car interior collects a particular kind of dirt: skin oils, food and drink spills, dust and general grime that get worked into textured plastics and down into the fibres of seats and carpets. A quick wipe smears it around; it doesn't lift it out.
Logic is a concentrated all-purpose cleaner with an active foaming action. Its cleaning agents — the surfactants that grab and hold dirt — loosen that grime and foam it up so it lifts away from the surface rather than spreading. Because it's a concentrate you dilute to suit the job: mixed stronger for ingrained grime, or right down for a light everyday clean and more delicate surfaces.
The result is a genuinely clean interior with a natural, factory-style finish — no greasy residue and no artificial shine. One important note: it's an effective alkaline cleaner, so it's worth testing colour fastness on fabrics first, and it isn't intended for continuous use on leather, which has its own dedicated products.

How To Use Logic
Always test for colour fastness on an inconspicuous area before you start, especially on fabrics and coloured trim. Skip continuous use on leather.
Dilute to suit the job — around 1:10 for general cleaning, 1:5 for heavier grime. Full detail is in the dilution ratios below. A trigger isn't supplied, so mix into your own spray or dilution bottle, and wear gloves and eye protection.
Apply the diluted cleaner to the surface — a light, even coverage is enough. Don't oversaturate fabric or let it pool.
Work it in with a detailing brush to lift grime out of textured plastics and the fibres of seats and carpets. Let the active foam do the work.
Remove with a clean microfibre cloth, turning to a dry side as you go. On fabric, blot to lift the loosened dirt and let it dry.

Dilute to suit the surface — lighter for delicate fabrics, stronger for ingrained grime. A trigger isn't supplied, so mix into your own bottle.
