Degreaser by COLOURLOCK

Dyeing and Repairing Begin with the Degreaser from COLOURLOCK

What is the Degreaser from COLOURLOCK? The preparation step before every leather dye job, repair, or sealing: COLOURLOCK "Degreaser" removes body oils, care product residues, and dirt films from pigmented smooth leather and faux leather without using solvents, ensuring that primers, colors, and top coats adhere permanently. Developed from practical leather repair experience, now under the umbrella of Koch-Chemie.

Degreaser from COLOURLOCK is the work step that detailers call Step 0: creating a grease-free surface before dyeing, repairing, or sealing even begins. COLOURLOCK "Degreaser" removes body oils, residue from care products, and dirt films from the surface of pigmented smooth leather and faux leather without the use of solvents — it is surfactant-based, dries without leaving streaks, and is available in container sizes ranging from 100 ml to 1 liter. This is because fillers, primers, and leather dyes only adhere to a surface that is free of grease.

• Adhesion is created during degreasing, not during color application. Body oils, sunscreen, and care product residues form an invisible barrier layer on which primers and dyes cannot bond. The degreaser removes this layer and leaves behind a matte, uniformly bondable surface — the foundation for any dyeing or repair result intended to last longer than a few weeks.
• Solvent-free instead of using white spirit, acetone, or alcohol. The classic forum recommendations for degreasing leather are all solvents — and these are precisely what attack the existing color and protective layer. COLOURLOCK "Degreaser" works instead with surfactants: it dissolves grease and residues from the surface without damaging the coating or drying out the leather.
• Three container sizes for three project scales. 100 ml is sufficient for steering wheels, gear shift boots, and small parts; 250 ml for individual seats and furniture surfaces; and the 1-liter bottle for complete sets and regular workshop use. Because the product is applied sparingly from a cloth, even the smallest container lasts through several projects.

Practical tip from Detailing1: The most frequent reason why a leather dye job peels off after a few weeks is not a color defect, but a skipped step: the leather was dyed while still "cared for." Leather care products leave behind exactly those grease- and silicone-containing films that no dye can penetrate. Therefore, always perform a wipe test before any dyeing: drag a white cloth with a little COLOURLOCK "Degreaser" across the surface in strips — as long as the cloth turns gray or yellow, grease is still present. Only when the cloth stays clean and the surface appears uniformly matte is it time for the primer and color.

Grease is the barrier layer that causes every leather dye to fail

Leather dye rarely fails across a large area. It peels off where hands have been for years: on seat bolsters, steering wheel rims, and armrests — and almost always, an invisible layer of grease lies beneath.

Body oil, sunscreen, hand cream, and residues of old care products migrate into the leather surface over months. Individually, none of these layers are noticeable, but together they form a film that acts like a release agent. A leather dye needs direct contact with the surface to bond — on a film of grease, it merely sits on top. In automotive painting, no one would think of spraying onto an uncleaned metal panel; the mechanism is the same for leather, just less visible.

The complaints we receive at Detailing1 almost always tell the same story: the dye looked perfect on the first day and began to peel after a few weeks, specifically in the grip zones. Not because the dye was bad, but because it never had contact with the leather. The mistake happens before the first drop of color — and that is exactly where this category comes in.

The problem does not stop at the car seat. Furniture edges where forearms rest daily, bag handles, shoes, steering wheels, and gear levers: everywhere skin regularly touches leather, the same film builds up. The physics of adhesion is the same on a sofa as it is in a vehicle interior — and so is the preparation step required beforehand. Even faux leather is no exception: modern seating systems often combine both, and the same rule applies to the coated plastic surface — without a grease-free surface, there is no adhesion.

Clean first, then degrease, then prime and dye

The order of leather preparation is non-negotiable: thorough cleaning, degreasing, complete drying — and only then primer, dye, and top coat.

The process starts with a leather cleaner: it removes loose dirt, dust, and water-soluble residues. What it does not catch are greases, silicones, and ingrained care films — that is exactly what the degreaser is for. COLOURLOCK "Degreaser" pulls this layer from the surface and leaves the leather uniformly matte. Only this matte surface is the basis for everything that follows.

The leather primer is applied to the grease-free surface: COLOURLOCK "Leather Primer" acts as an adhesion promoter, connecting the leather substrate to the new color layer. Afterward, the leather dyes are applied, followed by a top coat to seal the result. Each of these layers relies on the one below it holding fast. If the chain breaks during degreasing, it breaks everywhere.

The same preparation applies to repairs and sealants. Anyone filling a crack on a seat bolster needs grease-free edges so that the repair compound bonds to the flanks instead of just lying in the crack. And anyone wanting to seal a freshly treated surface afterward will seal the grease film right along with it if they haven't degreased. Therefore, the degreaser is not just a dye-prep product, but the common starting point for all three paths: dyeing, repairing, and protecting.

Between degreasing and priming, drying is a separate step. Residual moisture from the degreaser hinders adhesion just as much as grease does — therefore, wait until the surface has dried completely. This step costs no work time, only patience. It is the moment a quick project becomes a durable one.

Surfactants instead of white spirit. Degreasing without solvent risks.

The classic forum recommendations for leather degreasing are white spirit, acetone, alcohol, and isopropanol. All four do indeed degrease — and all four have the same problem: they do not distinguish between the grease and the color layer underneath.

Solvents can dissolve the binders of the existing leather dye, extract plasticizers from the coating, and dry out the fibers. On robust, pigmented leather, this sometimes goes well — professionals also work with solvents in controlled doses. But the line between degreased and dissolved is thin, and you only see it when it has been crossed. We regularly receive photos of steering wheels that were "cleaned" with alcohol: dull, light-colored scuffed areas where there was previously only greasy shine. A degreasing problem has turned into a dye project.

COLOURLOCK "Degreaser" takes a different path. Its surfactants encapsulate greases and polymer residues; the dissolved layer is absorbed and removed with a cloth. The color and protective layer remain untouched, the leather does not dry out, and the degreaser evaporates without streaks or residue from the surface. This is why it is used before dyeing and repairs without changing the substrate it is meant to prepare.

Surfactants also reach things that are not even body oils: silicone films from cockpit sprays, residues of gloss-enhancing care products, and the polymer residues of old sealants. These layers do not feel greasy, but they act as release agents nonetheless — and these are precisely what most instructions overlook. A pass with the degreaser clears both: the grease and the films on top of it.

You can see the result with the naked eye: the treated surface appears matte instead of greasy. Do not let this confuse you — matte is the working state here, not the final state. After dyeing and applying the top coat, the desired finish returns, this time on a layer that holds.

Apply sparingly to the cloth, work in strips, let dry completely

The application can be explained in one sentence: apply a little COLOURLOCK "Degreaser" to a cloth or pad, work it into the surface in smooth, steady strips, and remove dissolved grease with a clean cloth.

The degreaser belongs on the cloth, never directly on the leather — this way, you control where and how much product is working. On high-stress zones like seat bolsters, steering wheel rims, or furniture edges, repeat the process until the cloth stays clean. The wipe test from the practical tip is your progress indicator: gray or yellow on the cloth means keep going; a clean cloth means you are finished.

Two mistakes we see more often than any others: too much product and circular scrubbing. A soaked cloth only redistributes dissolved grease instead of removing it — applying it sparingly and turning the cloth often works better than pressure. And you should work in overlapping strips, not in circles: strips are controllable, while circles leave untreated islands that later appear as gaps in adhesion. Then there is the temperature: on sun-heated seats or a steering wheel in the middle of summer, the degreaser evaporates before it can work — it is better to work in the shade or with the door open, just as with any detailing step.

Afterward, wait until the surface has completely dried before applying filler, primer, or dye. From our own professional experience: a steering wheel can be degreased including drying in a good fifteen minutes; a complete seat set takes about an hour. Measured against the hours that a clean dye job takes, this is the smallest item in the entire project.

Aniline leather, suede, and absorbed grease stains are different challenges

The boundaries are clearly drawn: COLOURLOCK "Degreaser" belongs on pigmented smooth leather and many faux leathers — not on open-pored aniline leather and not on suede.

The reason lies in the structure. Pigmented leather carries a closed color and protective layer upon which the degreaser can work without penetrating. Aniline leather and suede do not have this layer: their open pores absorb liquid, and instead of a uniformly degreased surface, you get rings and dark spots. For these types of leather, the path is through a gentler, leather-specific preparation — not through the degreaser.

The second boundary is depth. The degreaser works on the surface and prepares areas — it does not reach grease that has migrated into the fiber structure over months. When we receive inquiries about dark, greasy spots on headrests or armrests, we first check whether the grease is on or in the leather: if the wipe test does not make it lighter, it is too deep. Then the degreaser takes over — the COLOURLOCK "Grease Absorber Paste" pulls absorbed grease out of the fiber structure instead of working on the surface.

And a third boundary that needs to be honestly stated: degreasing repairs nothing. Scuffed-off color, cracks, and faded areas remain exactly as visible after degreasing as they were before — often even more so because the greasy shine that was masking them is gone. The degreaser does not make these damages go away. It makes them treatable.

Which container size fits which project

The choice is uncomplicated because it only depends on the project size: 100 ml for a steering wheel, gear shift boot, and small parts; 250 ml for individual seats and furniture surfaces; 1000 ml / 1 liter for complete sets and regular use. If you are dyeing for the first time and don't yet know how many passes your surfaces will need, 250 ml is the safe middle ground: enough reserve for repetitions in the grip zones without having to jump straight to the workshop format.

All three sizes are the same product: the solvent-free COLOURLOCK "Degreaser". Because it is used sparingly from the cloth, even the small bottle is enough for several attempts — if you only want to prepare a greasy steering wheel for recoloring, 100 ml is fully equipped. The liter bottle belongs where dyeing and repairing happen regularly: in detailing shops, upholstery workshops, and repair centers.

Anyone planning the complete setup has already seen the next steps above: primer, dye, top coat — each layer on top of the one before it. The other problem solvers of the brand, from stain removers to adhesive removers, are collected in the category above: Back to Stain & Special Removers from COLOURLOCK.

And the thought that carries this category: a leather dye job is not decided at the color application stage, but in the fifteen minutes before. Those who degrease dye once. Those who skip the step dye twice — and end up degreasing the second time anyway.
