Cleaners developed from practical leather repair experience, graded according to leather type and level of soiling: a mild and a strong cleaner for pigmented smooth leather, plus a fiber-friendly specialist for open-pored aniline and nubuck leather.

Instead of a universal cleaner for everything, there are graded formulas: COLOURLOCK \"Leather Cleaner\" (Mild) for regular cleaning of coated smooth leather, COLOURLOCK \"Leather Cleaner\" (Strong) for greasy and long-neglected surfaces, and COLOURLOCK \"Aniline \u0026amp; Nubuck Cleaner\" for open-pored leather that would show water marks if treated with standard damp cleaning.

The specialist for these leathers works with minimal moisture and fiber-friendly surfactants—available in 250 ml and 1000 ml \/ 1 liter sizes.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e The most common mistake in leather cleaning is applying too much liquid directly onto the leather. We frequently receive inquiries about stained seats and marks in the perforation, and almost always the cleaner was sprayed on instead of being foamed. The correct method is the other way around: apply the cleaner to a pad, sponge, or soft brush, work the foam in section by section, and wipe it off with a slightly damp microfiber cloth. The leather should become damp, never wet—especially with perforated or ventilated seats, where excess liquid runs into the holes and leaves marks behind.\u003c\/p\u003e\n\n\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eEvery leather repair begins with cleaning\u003c\/h3\u003e\n\u003cp\u003eBefore a repair shop recolors a seat or closes a tear, the leather is thoroughly degreased—paint and glue will not adhere to skin oils. COLOURLOCK has been supplying exactly these businesses since 1995, and the brand's cleaners originated from this very step: not as an accessory, but as a prerequisite for everything else.\u003c\/p\u003e\n\n\u003cp\u003eYou can tell by the formulas. A cleaner used before recoloring must degrease thoroughly without dissolving the surface, otherwise the paint will adhere unevenly. For you, this means: the same cleaning performance that a detailer uses to prepare a lease return for handover, available in containers for home use.\u003c\/p\u003e\n\n\u003cp\u003eUncleaned leather ages faster than many realize. Skin oil binds dust and abrasion into a fine grinding paste, and every movement on the seat rubs it deeper into the creases—this is exactly where the dull, cracked spots that eventually necessitate repairs appear later. Cleaning is therefore not a cosmetic step, but the most cost-effective way to maintain the value of a leather interior.\u003c\/p\u003e\n\n\u003cp\u003eCleaning with COLOURLOCK is also a diagnostic tool. Only on clean leather can you see what is actual damage and what was merely dirt. We often see interiors where supposedly worn side bolsters turn out to be completely intact after a deep cleaning—the gray haze was just rubbed-in skin oil mixed with denim abrasion, not a damaged color layer.\u003c\/p\u003e\n\n\u003cp\u003eSince the acquisition by Koch-Chemie, the line is sold in our shop as Koch-Chemie × COLOURLOCK. This does not change the formulas or the grading according to leather type.\u003c\/p\u003e\n\n\u003ch3\u003eMild handles the routine and Strong takes care of the backlog\u003c\/h3\u003e\n\u003cp\u003eThe standard case in a car is pigmented smooth leather with an intact top coat, for which the \u003ca href=\"\/collections\/koch-chemie-colourlock-reinigung-lederreiniger-mild\"\u003emild leather cleaner\u003c\/a\u003e is almost always sufficient: COLOURLOCK \"Leather Cleaner\" (Mild) removes dust, light oils, and signs of use, maintains the matte factory look, and does not dry out the leather. At the same time, it prepares the surface for conditioning or sealing—both adhere significantly better to degreased leather. Available as 100 ml to try out and as 1000 ml \/ 1 liter for the ongoing routine.\u003c\/p\u003e\n\n\u003cp\u003eIf the grease is deeper, the \u003ca href=\"\/collections\/koch-chemie-colourlock-reinigung-lederreiniger-strong\"\u003estrong leather cleaner\u003c\/a\u003e takes over: COLOURLOCK \"Leather Cleaner\" (Strong) dissolves greasy steering wheels, old conditioning films, and deposits from years of neglect—the classic deep clean before the first conditioning, during detailing, or for lease returns. Despite the higher cleaning power, the formula remains tailored to leather; the pigment layer is not attacked.\u003c\/p\u003e\n\n\u003cp\u003eA different rule applies to open-pored leather, which is where the \u003ca href=\"\/collections\/koch-chemie-colourlock-reinigung-anilin-nubukreiniger\"\u003eAniline \u0026amp; Nubuck Cleaner\u003c\/a\u003e comes in: COLOURLOCK \"Aniline \u0026amp; Nubuck Cleaner\" cleans aniline leather, nubuck, and other suede-like leathers with fiber-friendly surfactants and so little moisture that the absorbent structure does not become soaked—the specialist in the series for surfaces where the two smooth leather cleaners should not be used.\u003c\/p\u003e\n\n\u003cp\u003eThe grading is intended as a system: the Mild maintains the condition, the Strong resets it, and the Aniline cleaner protects the exception. Those who keep up the routine with the mild cleaner rarely need the deep clean—that is exactly the idea behind it.\u003c\/p\u003e\n\n\u003ch3\u003eFirst, the leather type counts, then the degree of soiling\u003c\/h3\u003e\n\u003cp\u003eThe most important decision is not driven by the dirt, but by your leather. Whether the surface is coated or open-pored determines the choice of cleaner—how strong it needs to be is only the second question.\u003c\/p\u003e\n\n\u003cp\u003ePigmented smooth leather has a thin polyurethane top coat: a flexible color and protective skin that sits like a varnish over the actual hide. Skin oil, abrasion, and dust settle into its microstructure and rarely penetrate deeper. This means for you: the surface can handle a damp, foam-based cleaning because the top coat shields the leather underneath.\u003c\/p\u003e\n\n\u003cp\u003eMild and Strong differ in surfactant strength. Surfactants are wash-active molecules where one end grabs onto the grease and the other stays in the water—this makes grease that was stuck in the structure rinsable. The Strong version uses them in a significantly higher concentration. You can tell by this: where the Mild has to be applied twice to a greasy steering wheel, the Strong removes the grease in one pass.\u003c\/p\u003e\n\n\u003cp\u003eAniline and nubuck leather do not have this protective skin. Liquid is drawn in by capillary action—the open pores absorb it like a wick, and a normal cleaner leaves behind exactly the dark marks it was supposed to remove. The \"Aniline \u0026amp; Nubuck Cleaner\" therefore works with low moisture and lifts dirt instead of massaging it in. Semi-aniline falls in between: thinly pigmented and significantly more sensitive than fully coated leather—in case of doubt, treat it like open-pored leather.\u003c\/p\u003e\n\n\u003cp\u003eThere are two things none of these cleaners can do, and these should be stated honestly. Worn-off pigment layers, scratches, and faded color are a case for the COLOURLOCK dyeing and repair line, not a cleaning issue. And deeply embedded stains in open-pored leather—oil, ballpoint pen, old water marks—can only be partially removed by the Aniline cleaner; for this, there are \u003ca href=\"\/collections\/koch-chemie-colourlock-reinigung-spezialentferner\"\u003estain and special removers\u003c\/a\u003e with targeted formulas for each type of stain.\u003c\/p\u003e\n\n\u003ch3\u003eThe cleaner belongs on the pad and never on the leather\u003c\/h3\u003e\n\u003cp\u003eThe basic rule is in every COLOURLOCK manual, yet it is still the most frequently ignored: the cleaner goes on the pad, sponge, or brush—never directly onto the surface. This allows you to dose it in a controlled manner and keeps the moisture exactly where it belongs.\u003c\/p\u003e\n\n\u003cp\u003eThe process itself is completed in just a few minutes. Remove loose dust dry, foam up the cleaner, work it into section by section with circular motions, and wipe up the dissolved residue with a slightly damp microfiber cloth. Then let it air dry. For aniline leather, an additional rule applies: work from seam to seam, evenly and without strong rubbing, to ensure no visible transitions appear.\u003c\/p\u003e\n\n\u003cp\u003eFor nubuck, one extra step is added before and after: brush off the loose dirt carefully before cleaning, and after drying, fluff up the pile with a soft brush. This brings back the velvety feel instead of having the fibers lie flat and shiny.\u003c\/p\u003e\n\n\u003cp\u003eFor greasy areas—steering wheel rims, seat bolsters, entrance edges—a second pass is the method of choice, not more pressure. We receive most application questions regarding the steering wheel, and almost always the answer is the same: cleaning patiently twice with the appropriate cleaner beats cleaning once aggressively. Pressure polishes the grease into the structure instead of drawing it out.\u003c\/p\u003e\n\n\u003cp\u003eFreshly cleaned leather is degreased and therefore unprotected. Consequently, \u003ca href=\"\/collections\/koch-chemie-colourlock-pflege-lederpflege\"\u003eleather conditioner\u003c\/a\u003e should be applied to the surface immediately afterward—it keeps the fibers supple and makes it harder for new dirt to adhere. A proven rhythm is: mild cleaning every one to four weeks depending on usage, and deep cleaning with the Strong version only at the start of the season or when taking over a vehicle.\u003c\/p\u003e\n\n\u003ch3\u003eAll-purpose cleaners clean leather too thoroughly\u003c\/h3\u003e\n\u003cp\u003eAll-purpose and interior cleaners degrease reliably—and that is exactly the problem with leather. They do not distinguish between the skin oil on the top coat and the natural oils that keep the leather itself supple.\u003c\/p\u003e\n\n\u003cp\u003eFurthermore, there is the chemistry: many universal cleaners are alkaline, meaning they have a high pH value, which saponifies oils particularly aggressively. This is the right choice for plastic and carpet. On leather, regular use leaches the surface—the leather becomes dull, dry, and brittle in the creases. COLOURLOCK cleaners are tailored to the top coat and leave the plasticizers that keep it flexible intact.\u003c\/p\u003e\n\n\u003cp\u003eWe advise against home remedies just as strongly as we do for conditioning. Dish soap degreases in an uncontrolled manner, curd soap leaves alkaline residues, and wet wipes often contain conditioning additives that remain as a greasy film. We regularly see seats that have been treated like this for years—the deep cleaning then takes longer than any normal routine because the residues of the home remedies must be removed first.\u003c\/p\u003e\n\n\u003cp\u003eAnd sometimes you don't need a cleaner at all. For occasional dust, a damp microfiber cloth is perfectly sufficient. A leather cleaner comes into play as soon as grease is involved—recognizable by a greasy shine, sticky feel, or the gray haze on light-colored leathers. This honesty is part of the classification: those who dust their leather weekly purchase new supplies less often.\u003c\/p\u003e\n\n\u003ch3\u003eWhich leather cleaner fits your leather\u003c\/h3\u003e\n\u003cp\u003eThe decision comes down to two questions. First question: How does your leather react to a drop of water in an inconspicuous spot? If the spot darkens, the leather is open-pored—then the COLOURLOCK \"Aniline \u0026amp; Nubuck Cleaner\" is the clear choice, regardless of the level of soiling. If the drop beads up, your leather has a coating and can handle the two smooth leather cleaners.\u003c\/p\u003e\n\n\u003cp\u003eSecond question: What does the leather look like today? Well-maintained and regularly cleaned means COLOURLOCK \"Leather Cleaner\" (Mild) is your permanent solution. Greasy, sticky, or untouched for years means using COLOURLOCK \"Leather Cleaner\" (Strong) once for the deep clean—afterward, the Mild handles the routine, and the Strong goes back on the shelf for a long time. It is simply oversized for the weekly round—used in a targeted way, it remains a tool, but as a permanent solution, it would take more from the leather than necessary.\u003c\/p\u003e\n\n\u003cp\u003eLeather doesn't end at the car seat, and neither does this cleaning line: from leather detergent for clothing to upholstery and Alcantara cleaners, and shoe and sneaker cleaners, you can find all other cleaning products from the brand one level higher: \u003ca href=\"\/collections\/koch-chemie-colourlock-reinigung\"\u003eBack to COLOURLOCK cleaning\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eAnd the philosophy behind these cleaners: COLOURLOCK has been earning its living for three decades with repair and recoloring—the cleaners are the tool that clarifies beforehand whether it even needs to come to that. The difference between \"needs to be recolored\" and \"was just dirty\" is surprisingly often a half-hour with the right cleaner. Only clean leather can be truly evaluated, and the verdict is usually better than feared.\u003c\/p\u003e\n","products":[{"product_id":"koch-chemie-colourlock-leather-cleaner-mild-lederreiniger","title":"COLOURLOCK \"Leather Cleaner\" (Mild) — cleaner for normally soiled pigmented smooth leather","description":"\u003ch2\u003eCOLOURLOCK Leather Cleaner (Mild) — a gentle cleaner for regular leather care\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eWhat does COLOURLOCK Leather Cleaner Mild do? — It lifts everyday grime, light grease and wear marks off pigmented smooth leather extra gently, keeping the natural matte surface intact without drying it out.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eCOLOURLOCK Leather Cleaner (Mild)\u003c\/strong\u003e is your first pick when you want to clean pigmented smooth leather regularly and keep the material happy.

For the best result, follow up with a suitable care product or impregnation to shield the open-pore fibres from future soiling.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCommon questions about COLOURLOCK Aniline \u0026amp; Nubuck Cleaner\u003c\/h2\u003e\n\u003ch4\u003eCan I use the cleaner on all nubuck and aniline leathers?\u003c\/h4\u003e\n\u003cp\u003eYes.

The formula comes straight from professional COLOURLOCK technology and lifts deep-set build-up where milder cleaners just give up.

Since modern automotive leather has a PU topcoat, grease and abrasion tend to settle into the micro-structure of that layer. The cleaner breaks those bonds without softening the protective coat. According to the maker, the formula is dialled in to be strong enough for stubborn residue yet soft enough to keep the matte factory look. On greasy steering wheels you really see it work: it pulls the oils out of the grain and brings back the original grip and the matte finish.\u003c\/p\u003e\n\u003ch3\u003ePrep, application \u0026amp; the best cleaning routine\u003c\/h3\u003e\n\u003cp\u003eBefore you get going with \u003cstrong\u003eLeather Cleaner Strong\u003c\/strong\u003e, knock off loose dirt with a microfibre cloth. You put the cleaner onto a cleaning pad, a brush or a cloth — never straight onto the leather. Work the foam in with circular motions until the dirt lets go. Then wipe the residue off with a clean, slightly damp cloth. On really greasy spots like steering wheels you may need a second pass. After every deep clean it pays to follow up with a matched care product or a rub protector, so the leather stays supple and dirt has a harder time taking hold next time.\u003c\/p\u003e\n\u003ch3\u003eResults, typical use cases \u0026amp; where it differs from mild cleaners\u003c\/h3\u003e\n\u003cp\u003eAfter the treatment the leather looks cleaner, more matte and feels noticeably grippier. Heavy soiling, shiny patches from skin oils and worked-in abrasion are clearly reduced or fully gone. The \u003cstrong\u003eStrong Cleaner\u003c\/strong\u003e is the one to reach for on heavily used cars, full reconditioning jobs, lease returns or older interiors. For light dirt, though, the mild version is enough to clean the surface gently. The Strong Cleaner is no substitute for scratch or colour correction — for visible wear in the pigment layer, products like Leather Fresh or Fluid Leather are the way to go.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCommon questions about COLOURLOCK Leather Cleaner (Strong)\u003c\/h2\u003e\n\u003ch4\u003eCan I use the Strong Cleaner on any leather?\u003c\/h4\u003e\n\u003cp\u003eOnly on pigmented smooth leather.
