Interior Detailing From Scratch: The Complete Guide

The exterior gets all the glory in detailing circles, but a car's interior tells just as much of a story. Dust-coated vents, grimy leather, sticky trim, and stale smells are things you live with every single day — and they're all entirely fixable. Here's how to detail your car's interior properly, from empty seats to a genuinely fresh finish.

What you'll need

Before starting, gather everything together so you're not hunting for products mid-job. For a full interior detail you'll need:

Step 1: Remove and vacuum

Take out the floor mats, any boot liners, and any loose items. Give every surface a first pass with the vacuum — seats, carpets, footwells, and the boot. Use the crevice tool to get into seat rail gaps, between seat cushions, and along the base of the dashboard.

Don't skip under the seats. An extraordinary amount of debris accumulates there and it'll circulate around the cabin every time the door opens if you don't deal with it now.

Shake out and vacuum the floor mats separately, then set them aside to deal with later.

Step 2: Brush out vents and crevices

Air vents are dust magnets and they're almost impossible to clean properly with a cloth alone. The Duel Autocare "The Soft One" Detailing Brush — the smaller 17cm version — is perfect for working into each vent slat and dislodging the built-up dust inside. Brush into a running vacuum nozzle held nearby to capture the dust as it comes out.

Use the same brush around the gear lever, handbrake, cup holders, and any intricate trim areas. Getting dust and debris out of these crevices before applying any product means you're cleaning rather than just moving things around.

Step 3: Clean hard trim and the dashboard

For plastic and hard trim surfaces, a microfibre cloth lightly dampened with water works for light dust. For stickier grime, fingerprints, or ingrained dirt, a diluted interior all-purpose cleaner applied to the cloth (never directly to the surface near electronics) cleans effectively without leaving residue.

Work from the top of the cabin downward — dashboard first, then door cards, then centre console, then lower trim. This way any dust or debris you dislodge falls onto areas you haven't cleaned yet.

Step 4: Clean the leather

Leather needs a dedicated cleaner — household products and generic wipes are too harsh and can dry out or crack the surface over time. Infinity Wax Leather Cleanser is specifically formulated for all types of modern leather and faux leather. It removes ingrained dirt, body oils, and daily wear while leaving a soft, restored finish — without any drying or stripping effect.

Apply a small amount to a soft microfibre cloth or applicator and work into the leather in circular motions. Focus on the areas that take the most contact — seat bolsters, steering wheel, gear knob, and headrests. Wipe away residue with a clean cloth.

Once clean and dry, apply Gyeon Leather Coat. This hydrophobic sealant bonds to the leather and provides up to 3 months of protection against spills, sweat, UV fading, and the kind of dye transfer you get from dark jeans. It's the leather equivalent of waxing your paintwork.

Step 5: Clean the carpets and floor mats

For light soiling, a thorough vacuum is often enough. For heavier staining — mud, drink spills, general grime — a fabric cleaner and stiff brush does the job well. Use the Duel Autocare "The Stiff One" brush to agitate carpet fibres and loosen embedded dirt before vacuuming it out.

For the floor mats, clean them outside the car where you have room to scrub and rinse properly. Allow them to dry completely before putting them back in — damp mats under carpet can lead to mould.

Step 6: Clean the glass

Interior glass is often neglected but makes a significant difference to visibility and the overall look of the cabin. The inside of windscreens in particular build up a greasy, hazy film from outgassing plastics — this causes glare and is worth tackling properly.

Use a glass cleaner applied to a clean microfibre cloth, and work in overlapping strokes. Finish with a second dry cloth to buff off any streaks. Work on a cloudy day or in the shade if possible — glass cleaner drying too quickly in direct sun makes streaking much more likely.

Step 7: The finishing touch

With everything clean and protected, finish the interior with Duel Autocare Havana Air Freshener. This premium oil-based fragrance — notes of sugar cane and zesty lime — is applied by spritzing onto fabric surfaces and floor mats. Unlike aerosol fresheners that fade within days, Havana's zero-water, high-quality formula lasts considerably longer.

The result: a genuinely clean, fresh, properly detailed interior that feels as good as it smells.

Maintenance tips

Keeping the interior in good shape between full details is much easier than starting from scratch each time:

  • A quick vacuum and wipe-down once a fortnight takes 10 minutes and prevents build-up
  • Keep a pack of quality microfibre cloths in the car for quick wipe-downs
  • Re-apply Gyeon Leather Coat every 3 months to keep leather sealed and protected
  • Deal with spills immediately — the longer they sit, the harder they are to remove
