Professional Leather Stitch Masking Fluid for Recoloring

LeTech Leather Masking Fluid is a professional water-based stitch masking solution designed to protect thread and contrast stitching during leather recoloring and refinishing. This fast-drying formula forms a flexible protective film over seams, preventing overspray, dye penetration, and unwanted color contamination.

Contrast stitching plays a critical visual role in automotive interiors, furniture, and luxury leather goods. During recoloring, even minor overspray can permanently alter thread color and ruin the final appearance. Leather Masking Fluid creates a removable barrier that keeps stitching clean, sharp, and original.

What This Stitch Masking Fluid Does

This professional masking compound temporarily seals leather seams and threads before spraying or applying leather dye. Once dry, it forms a thin elastic coating that shields the thread without damaging texture or color. After refinishing, it can be easily removed without leaving residue.

Prevents dye overspray on stitching
Protects contrast thread during recoloring
Maintains original thread color and texture
Forms flexible removable protective film
Supports precise professional restoration work

Professional Applications

Automotive Interiors: Contrast seat stitching, dashboards, door panels

LETECH LEATHER LIQUID DEGREASER

EXPERT LINE — DEEP OIL EXTRACTION & SURFACE DEGREASING

A professional solvent-active liquid degreaser designed to extract embedded oils, body grease and contamination from leather surfaces.

Removes deeply absorbed oil, perspiration, silicone and greasy residues without aggressive stripping — restoring a clean, stable surface ready for repair and refinishing.

LeTech Leather Degreaser (Gel) – Professional Oil & Grease Remover for Leather Restoration

(0)

$43.90 USD

Professional Leather Degreaser for Oil & Grease Removal

LeTech Leather Degreaser is a professional absorbent gel designed to remove deep oil stains, body oils, grease, sweat, and contamination from leather before recoloring and restoration. Darkened steering wheels, shiny headrests, greasy jacket collars, and sticky leather surfaces are all caused by oil saturation inside the leather structure — not just on the surface. This product extracts embedded oils from within the fibers, preparing the leather for high-quality repair and refinishing.

Formulated with Vibrant Plus+ technology, this thick extraction gel penetrates the leather grain, absorbs contamination, and transforms into a powder as it dries — physically pulling grease to the surface. It acts as a visual indicator: white on clean areas, yellow to dark brown where oil has been successfully removed.

What This Leather Degreaser Does

Unlike surface cleaners, this professional leather degreaser targets oil trapped inside the leather structure. Complete oil removal is a critical step before recoloring, coating, or repair. Skipping this stage can lead to poor adhesion, peeling, or premature coating failure.

Removes body oils (sebum) from steering wheels and armrests
Extracts grease from furniture headrests and cushions
Eliminates oil stains from food and air freshener spills
Reduces ink transfer and ballpoint pen marks
Prevents coating failure during leather recoloring

Professional Applications

Automotive Interiors: Darkened steering wheels, gear shifters, seats, and armrests
Furniture Restoration: Oil-saturated sofa headrests and hand-contact areas
Leather Apparel: Greasy jacket collars and cuffs
Luxury Leather Goods: Handbag handles, footwear, equestrian items
Marine & Aviation Interiors: High-contact leather surfaces

Why Oil Removal Is Critical Before Recoloring

Oil contamination blocks adhesion. If grease remains inside the leather, new dye or coating will not properly bond. LeTech Leather Degreaser improves adhesion performance by ensuring the leather structure is fully decontaminated before refinishing. This significantly increases durability and longevity of restoration work.

Technical Specifications

Technology: Vibrant Plus+ oil extraction system
Form: Thick absorbent gel
Drying Time: Approximately 30 minutes (depending on environment)
Application Method: Brush application
Indicator System: White when clean, yellow/brown when oil extracted
Compatible Leather Types: Aniline, Semi-Aniline, Pigmented, Pull-Up, Antique Finish
Not Recommended For: Bi-cast leather (may become tacky)

Compatible Leather Types

Aniline leather
Semi-aniline leather
Pigmented leather
Pull-up waxed leather
Antique two-tone finishes

Suitable for use on leather of all colors and textures.

Frequently Asked Questions

Does Leather Degreaser remove body oil from leather?

Yes. LeTech Leather Degreaser is specifically designed to extract body oils (sebum), sweat, and grease from deep within the leather structure. It removes contamination that regular surface cleaners cannot reach.

Is this product necessary before leather recoloring?

Absolutely. Oil trapped inside leather prevents proper adhesion of dyes and coatings. Degreasing is an essential preparation step to ensure long-lasting restoration results.

Can it remove dark shiny areas on steering wheels?

Yes. Darkened and shiny steering wheels are typically caused by oil saturation from hands. This product extracts embedded grease and prepares the surface for refinishing.

Does it remove ink stains from leather?

It can help reduce ballpoint pen marks and certain dye transfers, especially when used as part of a professional restoration process.

How many applications are required?

Severely oil-contaminated leather may require multiple applications. Repeat the process until the dried product remains white, indicating full oil extraction.

Is it safe for all types of leather?

Compatible with aniline, semi-aniline, pigmented, pull-up, and antique finished leather. Not recommended for bi-cast leather.

Why does the product change color while drying?

The color change is a visual indicator. Yellow or brown discoloration shows that oil and grease have been successfully absorbed from the leather.

How to use

1) Applying Surface Repair

Apply in any convenient way: sponge applicator, spatula, or brush.
Carefully fill fine cracks with thin layers.
Dry using a hair dryer. The water-based formula dries within minutes.
Expect slight shrinkage while drying—apply multiple thin layers, drying each layer thoroughly.
If you need tinting: add 10% LeTech Leather Colourant (by volume) to achieve the desired shade.

2) Applying Leather Colourant

Shake the colorant thoroughly before use.
For the best decorative result, apply evenly in thin layers by spraying (spray gun or airbrush).
Pneumatic spraying: dilution with distilled water is allowed.
Nozzle diameter: 0.5–1.2 mm
Pressure: 1.1–8 bar (depending on equipment)
Compressed air must be free from water and oil.
Before spraying: mix thoroughly and filter through 190 micron filter.
Manual application (sponge/brush/roller) is also allowed for spot repairs, base layers, and color restoration.

3) Protective finishing

After recoloring, protect the surface with LeTech Leather Top Coat.
For enhanced durability: add Cross Linker X (5–10%) of total product volume.
Top Coat is best applied by spraying (airbrush or spray gun) for an even layer.
Avoid overly thick coats—excess finish may affect color and increase leather stiffness.
Usable after 2–3 hours, but full curing/crystallization takes 8–12 hours (depends on temperature and humidity).
Do not use cleaners or apply care products during the first week. After one week, use without limitations.

4) Tool cleaning

After completing all steps, wash tools thoroughly with water.
If needed, use LeTech Leather Prep paint solvent.

Important notes

Follow the manufacturer’s instructions to ensure effective and safe use.
Always test on a small, inconspicuous area before full application.
