NOMA 686 – Professional Leather Seat Cleaner & Conditioner Kit for Home Use

NOMA 686 is a deep-cleaning leather seat care kit built to American standards, delivering an optimized 2-step process for caring for your car’s leather interior at home. This kit is nothing like ordinary cleaning solutions — it combines deep cleaning and restorative conditioning in one professional detailing-grade process.

Why Does Leather Need Dedicated Cleaning and Conditioning?

After 2-3 years of use, leather car seats commonly develop the same issues: the surface dulls and stiffens, fine cracks appear especially in high-contact seating areas, and sweat and oils build up and become hard to remove. Instead of just wiping with water (which doesn’t clean thoroughly and can actually accelerate leather deterioration), NOMA 686 delivers a 2-step process: Deep Cleaning and Optimal Conditioning.

Replacing leather car seats is expensive ($1,500-$5,000 per set), and professional detailing service isn’t cheap either ($150-$300 per visit). NOMA 686 lets you get professional-level care at home for a fraction of the cost.

NOMA 686’s Deep 2-Step Kit

The kit includes 2 bottles, 200ml each:

Bottle 1 – Interior Cleaning Agent: With a pH-neutral formula, this cleaner breaks down stubborn stains, oils, sweat, and bacteria on the leather surface without stripping or damaging the collagen structure. Mild surfactants preserve the leather’s natural oils, preventing that dry, rough feel after cleaning.

Bottle 2 – Interior Curing Agent: This conditioning formula penetrates deep into the leather’s structure, replenishing moisture and nutrients. It contains a UV blocker to prevent sun damage over time, and forms a thin protective layer that resists new dirt buildup.

Noticeable Cleaning and Conditioning Results

After using the NOMA 686 kit, leather is deep-cleaned with no lingering stains, and the surface becomes soft and supple again. Color looks fresh and even, with no fading or discoloration. The UV-protective layer keeps leather from fading over time, and seats are left with a pleasant, natural leather scent.

The 400ml two-bottle kit is enough to treat a full 5-seat sedan’s leather about 5-7 times. For an SUV or 7-seater, it’s enough for 3-5 full treatments. Cleaning results are visible immediately after step 1, and conditioning results show right after step 2, with soft, naturally glossy leather.

Suitable for Every Type of Premium Leather

NOMA 686 is safe for premium genuine leather (Nappa, Full Grain) and high-quality faux leather. However, you MUST test on a small, hidden spot before applying it broadly, as premium genuine leathers can react differently to chemicals. This product is NOT suitable for suede, nubuck, or fabric upholstery.

How to Use NOMA 686 at Home

Before you start: Park your car somewhere well-ventilated, away from direct sunlight. Thoroughly vacuum the entire seat and all crevices. Prepare the included sponge applicator pad and 2 separate clean microfiber towels, one for each step.

Step 1 – Clean (Bottle 1): Shake the bottle well for about 10 seconds, and apply a moderate amount onto the sponge applicator pad (about 2-3cm in diameter). Work it over the seat surface in small circular motions, starting from the seatback down to the cushion. Scrub gently in circular motions, focusing on soiled areas. Wipe clean with microfiber towel #1 in one direction. Repeat section by section until the whole seat is clean. Let the seat dry completely (5-10 minutes) before moving to step 2.

Step 2 – Condition (Bottle 2): Shake bottle 2 well for about 10 seconds. Apply a moderate amount onto a clean sponge applicator pad and work it evenly over the seat surface in small circular motions, covering it fully. Let it sit for 3-5 minutes so the Curing Agent absorbs into the leather. Wipe gently with microfiber towel #2 in one direction to remove excess and bring out a natural shine. Avoid sitting on the seat for the first 30-60 minutes to let the conditioning layer set. Leave car doors open to let the scent dissipate naturally.

Important Notes for Using NOMA 686

Always follow the correct order: Clean (Bottle 1) first → Condition (Bottle 2) second. Doing it in reverse traps dirt in the leather and prevents the conditioner from absorbing properly. Let the seat dry completely between the two steps (5-10 minutes). Never pour the product directly onto the seat — always apply to the pad first. Scrub gently; scrubbing too hard can scratch the leather surface. Use separate towels for each step to avoid cross-contamination.

How Often to Maintain Your Leather

NOMA 686’s protective layer lasts 1-3 months depending on use and conditions. Recommended schedule: daily drivers should treat their seats every 1-2 months, occasional drivers every 2-3 months, and vehicles parked outdoors frequently should be treated monthly for better UV protection. The product leaves no greasy or sticky residue — leather feels clean and breathable after use.

Safety and Quality Certification

NOMA 686 comes with a complete MSDS meeting GHS (Globally Harmonized System) standards – an internationally recognized chemical safety record. The product is officially imported with full customs documentation. It’s non-toxic when used correctly — avoid inhaling the spray directly, avoid eye and skin contact, and don’t spray near your face or children.

Extend the Life of Your Premium Leather Seats

Instead of investing in new leather seats ($1,500-$5,000), NOMA 686 from Doscom can extend your seats’ lifespan by 2-3 times. With regular care, leather seats can stay looking like new for 5-10 years. It’s a cost-effective solution that keeps your interior deeply clean, soft, and durable.
