FEYNLAB® interior portfolio — product map and three myths

FEYNLAB® interior portfolio — product map and three myths

FEYNLAB® interior range is segmented by substrate. This article is the hub: which cleaner, conditioner, and coating fits leather, Alcantara, textile, plastic, and matte trim — plus three myths that still drive bad DIY habits.

Portfolio map

Key products

Interior Cleaner

Universal interior surfactant cleaner — leather, plastic, Alcantara, textile, glass, dash. Smart surfactant chemistry:

• Neutral pH (~7.5).
• No silicones, oils, or petroleum.
• Surfactants collapse after cycle → minimal residue, no resoiling.
• Body-shop safe — no film that blocks coating adhesion.

Apply via towel (not direct on fabric), circles, short contact (≤10 s on Alcantara, ≤30 s elsewhere).

Leather Treatment

Water-based conditioner without petroleum oils. On pigmented leather it tunes surface behavior; on semi-aniline/aniline it hydrates the binder layer.

Frequency:

• Pigmented: 3–4× per year.
• Semi-aniline: every 1–2 months in heating season.
• Under ceramic: 2–3× per year.

Leather Coating

Silane-based ceramic for leather — covalent bond to PU clearcoat. Life 2–3 years; annual top-up.

Effects:

• Hydrophobic — sweat, water, coffee bead off.
• Barrier to denim dye transfer.
• UV protection for PU → longer leather life.
• Wears sacrificially instead of topcoat.

Textile / Textile V3

Coatings for fabric and carpet. Textile V3: nano-ceramic matrix + dual cure (RT + UV-assist).

• Textile: ~6 months, simpler application.
• Textile V3: 12+ months, UV block >99 %, 8 h + 24 h full use cure.

Apply with clay cloth or soft applicator — not a sprayer.

Plastic V2

Interior plastics (dash, door cards, tunnel). Preserves OEM gloss or matte — no silicone shine. ~12 month life.

Black Plastic

Renews and protects exterior black plastics; also door edges and tunnel trim in cabin. Restores carbon black without siloxane sling.

Matte Ceramic

Mat-safe ceramic for matte lacquer — common on matte dash inlays. No unwanted gloss (unlike standard Ceramic Lite on matte).

Three interior care myths

Myth 1: “Leather must be fed with oil”

On modern pigmented leather, oil does not feed the hide — it builds a grease film that traps dust and slowly abrades PU. The grain under 50 µm polyurethane does not absorb external “nutrition.”

Reality:

• Pigmented (~90 % of cars): water-based care or light coating only.
• Semi-aniline / aniline: hydration possible with proper water-based products only.

Detail: Why oil conditioners harm PU leather.

Myth 2: “Enzyme cleaner is always better”

Proteases, lipases, amylases need moisture and ~30–40 °C for full activity. In a dry winter cabin or a 70 °C summer cabin they denature.

For typical cabin soil (dust, sweat, cosmetics, coffee) modern smart surfactants outperform enzymes and leave less residue. Enzymes need full rinse or they can attack polymers (PU, PES). Combined with warmth and moisture, mold risk rises.

Reality: for ~95 % of cabin work, Interior Cleaner is faster, safer, residue-free. Enzymes belong in studio for specific organic cases (blood, pet) under control.

Myth 3: “Ozone is universal disinfection”

O₃ is a strong oxidant (E° = 2.07 V). It attacks rubber seals, PU foams, sensitive trim, some plastics. By-products: aldehydes, VOCs — new odors.

Safety: above ~0.3 ppm is toxic to people. Car must be sealed; long venting after. Ozone poorly reaches evaporator biofilm under the HVAC cover.

Better default for most cases: chlorine dioxide (ClO₂) — gentler on materials, shorter exposure, better leather/PU compatibility.

Detail: Ozone vs chlorine dioxide — risks and use.

DIY vs studio

DIY handles:

• Monthly Interior Cleaner maintenance.
• Semi-aniline Leather Treatment hydration.
• Light Alcantara dry brushing.
• Vacuuming carpets.
• Fresh stains (<24 h).

Studio handles:

• Full fabric/carpet extraction.
• Coating application (Leather, Textile V3, Plastic V2, Matte Ceramic).
• Alcantara de-pilling with electric tool + P1200 finish.
• HVAC decontamination (evaporator scope, ClO₂).
• Set denim dye transfer with top remover.
• Pre-sale / lease interior restoration.

Takeaways

• Start from the portfolio map — there is no universal interior product.
• Oil, enzymes, and ozone have niches, not default roles.
• Monthly Interior Cleaner is ~80 % of long-term result.
• Preventive coating saves money vs reactive studio correction.
