Complete Odor Destruction:
It permanently destroys both surface smells and deep odors trapped inside the core of the suede.
Color Protection:
A dedicated acid rinse locks natural dyes in place to prevent bleeding, color running, or ring stains.
Deep Conditioning:
It replaces the vital fats and oil diminished, returning your suede to its original flexible and soft feel.
Step 1: Smoke & Soot Remover 5.3 (pH 5.3).
Step 2: Acid Rinse Solution (pH 3.0)
- Role: A stabilizer that strips away suspended residue, balances harsh ash alkalinity, and locks down natural suede dyes.
Step 3: Smoke Sanitizer & Deodorizer (pH 4.7)
- Role: A targeted purifier that relaxes the outer fibers to completely neutralize surface-level smoke odors.
Step 4: Hydrator 3.3 (pH 3.3)
- Role: A deep penetrator that chases trapped down sub-surface odors and opens up internal pathways for vital fats and oil.
Step 5: Fatliquor 5.0+ (pH 5.0+)
- Role: Deep fatliquoring that replenished the dried-out core with rich fats and oil, restoring your suede's natural flexibility and softness.
Step 6: Conditioner 3.2+ (pH 3.2+)
- Role: A final surface conditioner that locks the replenishing fats and oil inside the fibers and creates a permanent barrier to repel future dirt.
1. Clean the Surface (Step 1):
Spray Smoke 5.3 to lift the soot, then immediately blot it clean with a white cotton terry cloth.
2. Stabilize the Material (Step 2):
Mist with Rinse 3.0 to lock in the colors.
Let the material air-dry until it feels slightly cool to the touch.
3. Destroy Odors (Steps 3 & 4):
Spray the Smoke 4.7, then follow right away with the Hydrator 3.3.
(For severe odors, wrap the wet material tightly in plastic wrap for 12 to 24 hours to force the product deep into the core).
Vacuum extract or blot the liquid while it is still wet.
4. Soften & Protect (Steps 5 & 6):
Apply the Fatliquor 5.0+ directly to the damp leather and let it dry completely for 24 hours.
Finish by misting the Conditioner 3.2+ to seal in the fats and oil, then gently brush the nap back up.
Can I skip Step 2 and go straight to the Deodorizer?
- No.
- If you skip the Acid Rinse, the leftover residue from Step 1 will mix with the deodorizer.
- This will drive the black soot particles deeper into the leather and cause permanent stiffness.
- Step 2 is mandatory to lock down the dyes and protect the fibers.
Is this kit safe for colored or dyed suede?
- Yes.
- Because Step 2 drops the liquid balance to an acidic pH 3.0, it actively fixes water-soluble aniline dyes in place to prevent bleeding.
- However, you should always test a small, hidden spot first before treating highly visible areas.
What items can I clean with this?
- This system is perfect for professional fire restoration on suede jackets, nubuck boots, fine aniline leather furniture, car upholstery, and luxury bags damaged by tobacco, campfires, cooking incidents, or wildfires.
The 3 Operational Movements and the 6 Steps of the Sequence:
Phase 1: Decontamination & Stabilization.
Phase 2: Sanitizing & Deodorizing.
Phase 3: Replenishing & Conditioning.
Step 1 (5.3) ──►
Step 2 (3.0) ──►
Step 3 (4.7) ──►
Step 4 (3.3) ──►
Step 5 (5.0) ──►
Step 6 (3.2)
Phase 1:
- Decontamination & Stabilization
Step 1:
- Smoke & Soot Remover 5.3 (Target pH: 5.3)
- By keeping the pH at 5.3, the fibers remain relaxed.
- This ensures the oily soot can be completely wiped away before any strong acids are introduced, which would otherwise permanently lock the soot into the material.
- Acid Rinse Solution (Target pH: 3.0)
- Sanitizing & Deodorizing
- Smoke Sanitizer & Deodorizer (Target pH: 4.7)
- The pH swings back upward toward a milder 4.7, allowing the tightly bound fibers to gently relax and expand once again
The Action:
- It targets the upper layers of the material, neutralizing surface-level smoke odors and providing aromatic purification.
The Synergy:
- This step acts as a chemical bridge.
- It safely prepares the fiber matrix for deep liquid penetration without shocking the material with an immediate, drastic chemical change.
Hydrator 3.3 (Target pH: 3.3)
The Science:
- The pH drops back down to 3.3 to maximize surface tension reduction and increase deep core wetting.
The Action:
- It drives deep into the cross-sections of the fiber matrix, chasing down sub-surface smoke vapor molecules that are trapped deep inside the material's core.
The Synergy:
- The Hydrator completely opens up the deep inner pathways of the fibers.
- This creates a wet, perfectly prepared channel for the essential oils and nutrients in the next stage to travel through.
- Replenishing & Conditioning.
Fatliquor 5.0+ (Target pH: 5.0)
The Science:
- The pH is raised to 5.0, which perfectly balances the internal electrical charge of the leather fibers, making them highly receptive to oils.
The Action:
- It replenishes vital fats and oil, back into the dried-out core of the material.
- This replaces the natural fats and oil that were destroyed by the intense heat and dry conditions of the fire.
The Synergy:
- Because the Hydrator (Stage 4) already mapped out and opened up the pathways, the Fatliquor can coat every individual fiber, restoring the material's original flexibility and velvety softness.
Conditioner 3.2+ (Target pH: 3.2)
The Science:
- The final step applies a permanent drop down to an acidic pH of 3.2, which acts as a final chemical "lock."
The Action:
- It seals the surface, binding the nourishing Fatliquor oils permanently to the fiber walls so they cannot leak out or migrate over time.
The Synergy:
- This completes the restoration.
- It forms a protective barrier against future soil, locks the nap of the suede into its ideal structural state, and guarantees that the neutralized smoke odors remain permanently destroyed.

1. Purpose:
3. Massage:
4. Reaction Time:
Let the product stand for 5 minutes to destroy surface odor molecules.
1. Purpose:
2. Controlled Saturation:
Generously spray Hydrator 3.3.
The pH drops to 3.3 to maximize surface tension.
For very stubborn odors, cover the area with plastic wrap for 12 to 24 hours.
4. Check:
The suede must be evenly softened and moist, ready to receive the fatliquor.
1. Purpose:
2. Wet application:
Apply Fatliquor 5.0+ directly onto the still-damp suede from step 4.
3. Capillary Penetration:
The fats and oil will follow the path traced by the Hydrator 3.3 to replenish the fibers deeply.
4. Complete Drying:
Allow the suede to air dry completely (preferably 24 hours).
As the water evaporates, the fats and oil bind to the fibers, restoring the suede's suppleness.
1. Purpose:
Once the leather is completely dry, vigorously brush the suede against the grain to recreate its velvety appearance.
3. Conditioning:
Spray a thin layer of Conditioner 3.2+ over the entire surface.
Allow to dry for 30 minutes .
Professional Tips
Phase 2:Do not allow the suede to dry completely between these steps.
The fiber matrix must remain slightly damp to allow the pH adjustment to occur evenly across the suede.
Tactile Assessment:
Feel the suede surface.
If it feels sticky, slick, or soapy, a heavy surfactant film remains.
Perform one more dry terry cotton towel blotting pass before proceeding.
Visual Inspection:
Ensure no visible black streaks or loose carbon ash remain on the surface.
If streaks are visible, spot-treat immediately with a light mist of Smoke 5.3, blot, and extract before moving to Phase 3.
───► (Apply Rinse 3.0) ───► [pH 3.0: Tightened/Stabilized Suede]Cross-Hatch Mist Application:
- Hold the Rinse 3.0 bottle roughly 10–12 inches (25–30 cm) away from the surface.
- Apply a light, even coat using a cross-hatch pattern (horizontal passes followed by vertical passes).
Chemical Penetration:
- Allow the Rinse 3.0 to dwell on the damp suede for 2 to 3 minutes.
- During this time, the acid actively neutralizes the alkaline smoke salts and locks down water-soluble dyes/tannins.
Resetting the Corium Nap:
- While the suede is still damp from the Rinse, take a clean, dry, stiff-bristle suede brush and gently groom the nap back up.
- Brush against the natural lay of the fibers to ensure the acid penetrates the roots evenly.
Final Moisture Control:
Blot the entire surface one last time with a fresh white terry cotton towel to remove any neutralized alkaline salts and excess moisture.
Dye Bleeding / Color Transfer:
If you notice color bleeding onto your white microfiber cloth during the Acid Rinse application, immediately stop.
This means the suede's original dye is highly unstable.
Lightly mist the area with Rinse 3.0 again without rubbing, blot instantly with a dry towel, and force-dry the area with a cold-air blower to lock the dye in place.
Fiber Stiffening:
If the suede feels stiff right after applying the Acid Rinse, the pH drop occurred too rapidly due to leftover alkaline ash deep in the suede.
Do not scrub.
Proceed directly to Stage 3 (Smoke 4.7 - pH 4.7) or Stage 4 (Hydrator 3.3) to re-relax and open the fibers safely.
Avoid using heat guns or temperatures above 30°C (86°F), as heat combined with an acidic environment will permanently bake and harden the wet collagen fibers.
Relative Humidity (RH):
If humidity is too high (>65%):
The acid rinse will sit wet for too long, increasing the risk of unstable dye migration.
Lightweight Suede (Garments, thin jacket linings, fine gloves):
45 to 60 minutes .
Medium Weight Suede/Nubuck (Upholstery, car interiors, standard footwear):
1.5 to 2.5 hours .
Heavy Weight / Thick Split Leathers (Rugged work boots, thick tool belts, heavy rugs):
3 to 4 hours.
- The Tactile Coolness Test: Press the back of a bare hand firmly against the suede surface. The material must feel cool and slightly damp to the touch, but not wet. It should hold roughly 15% to 20% residual moisture. [1, 2]
- The Nap Resiliency Test: Run a clean finger against the grain of the suede. The fibers should move completely freely, and a clear tracking line should be visible in the nap. If the fibers feel sticky, crunchy, or glued flat to the skin, the surface is not ready and requires more drying time or another gentle grooming pass with a soft suede brush. [1]
- Draft a troubleshooting checklist for technicians if the drying room humidity spikes unexpectedly.
- Provide the technical instructions for Stage 3 application once these drying conditions are met.
- Draft the Technical Data Sheet (TDS) layout for the Acid Rinse 3.0.
- Detail the drying times and environmental conditions (humidity/temperature) required before moving to Stage 3.
Leather Doctor® Kit S3.so, suede smoke and soot deodorizer kit is designed to eliminate soot and smoke odors. d’Smoke-4.7 is used in conjunction with Prep-4.4 to effectively remove the sticky micron size smoke particles that lodges in the leather pores and stitching seams.
It is the scrutinizing and removing of these off gassing sticky particles that will eventually solve the odor problem.
The sticky residue is removed with Cleaner-3.8 follows with Rinse-3.0. Hydrator-3.3 helps relax the leather structure, reduce surface tension for fat and oil replenishing.
Fatliquor LS-5.5 diffuses a classic leather scent besides penetrating and lubricating the leather structure for softness, suppleness and strength when dry.
The surface wear of the leather is greatly reduced with a rub-resistant Protector-S+ that enhances a non-stick silky-feel to shield against sticky soiling, besides healing and concealing lightening scuff and abrasion marks.
Note that the mentioned products suffix numbers denotes its pH value in this holistic approach in decontaminating body odors from suede leathers. For fine suede, treat it as nubuck (Kit N3.so) using nubuck Brush-2 / Eraser-4 instead.
This kit comes with reduced weight option to save on shipping thus the 250ml concentrate ratio such as Clean-3.8, Rinse-3.0, d’Smoke-4.7, Hydrator-3.3 and Fatliquor LS-5.5 has to be filled up with distilled water prior to use.
