What are the cleaning & care sets from COLOURLOCK? Each set pairs a cleaner with the care product matched to it and includes the tools for both steps. They're available for car leather by leather age, for sneakers, for removable leather items in the washing machine and for fabric convertible roofs.
Cleaning & care sets from COLOURLOCK are matched pairs of cleaner and care product, packed with the tools the job calls for. They cover four very different ways of working: seat leather gets wiped, sneakers get foamed, removable leather items get washed, and the fabric roof gets brushed and sealed. The formulas come from leather repair, where COLOURLOCK has been at home since 1995 — today under the Koch-Chemie umbrella.
Detailing1's tip from the shop: The most expensive mistake with a set is cutting corners on the step in between. We regularly get enquiries from customers whose freshly sealed convertible roof stops beading water after four weeks — and almost every time, after brushing it clean they only gave it one damp wipe instead of a thorough rinse. The cleaner's preservatives then stay in the fibres and act like a release agent: the sealant finds nothing to cross-link with. On a leather seat the same thing happens on a smaller scale, and it shows up as blotchy care sitting on the surface. So the same rule applies to every set: remove the cleaner completely or rinse until there's no foam, let it dry through, and only then apply the care product.
Care only works where the cleaner has done a clean job first. Anything else is preserved dirt.
Three things get in the way of the care product, and all three come from the cleaning step. The first is residue from the cleaner itself: preservatives and leftover surfactants form an invisible film that oils and polymers slide off. The second is residual moisture — water sits in the top coat and pushes out exactly the care that's meant to go in. The third is dirt that was loosened but not taken off, which shows up over a bigger area once it dries than it did before.
This is exactly where a set earns its money. The cleaner and care product in a set are tuned to the same residue balance: the cleaner loosens as much as the included tools can take back off, and the care product is tuned to what's left afterwards. Two random bottles from two different shelves don't share that understanding.
With the COLOURLOCK "Leather Wash Set" this becomes especially clear, because a third component comes into play. Before the actual wash, the leather soaks for an hour in a bath of colour fixative — an acidic solution that anchors the pigments in the fibres like a peg in the ground. The tell-tale sign: dark stitching on light leather doesn't bleed in the wash. Without that pre-soak, the wash concentrate would be a risk for any multi-coloured item, despite its mild formula.
There's a simple reason the brand thinks this way. COLOURLOCK comes from leather restoration and knows how a botched cleaning job ends: with re-dyeing. So a set is less a bundle deal than an insurance policy against exactly that.
The sets aren't split by vehicle class but by what you're holding in your hand. Four groups cover everyday use.
The usual case is fitted car leather. That's what the Leather-age care kits by COLOURLOCK are for, graded in three stages: the COLOURLOCK "New Leather Care" Set for leather up to about three years old, the COLOURLOCK "Smooth Leather Care" Set for aged factory leather beyond that, and the COLOURLOCK "Classic Car Leather Care" Set for well-worn classic car leather. What separates the stages is how much they re-nourish: restrained on young leather, which needs protecting on top, and much richer on a dried-out classic car seat that has to soften up again from the inside.
Sneakers are a substrate of their own, because one shoe has smooth leather, mesh, suede, faux leather and a rubber sole side by side. The COLOURLOCK "Sneaker Cleaner Set" handles this with a pH-neutral foam from a dispenser, plus a soft leather brush, cleaning sponge and viscose cloths. pH-neutral here means the cleaner sits at the same value as water and doesn't attack the tanning agents in the leather. Day to day, you'll notice it on suede that doesn't fade once it's dry.
Removable leather can go a step further. The COLOURLOCK "Leather Wash Set" handles leather jackets, motorcycle leathers, seat covers and sheepskins on a wool cycle at no more than 35 degrees, because its wash concentrate, made to a tanner's recipe, puts oils back in instead of rinsing them out. Regular detergents are alkaline and strip the leather of its softeners — leaving you with an item that feels like cardboard.
The fourth group doesn't touch leather at all. The COLOURLOCK "Cabrio Care Set" cleans and seals fabric convertible roofs: a pH-neutral concentrate that you mix 1:10 with warm water, and a water-based textile sealant that's massaged in with a sponge rather than sprayed. It dries breathable, so residual moisture from inside the car can escape and the roof doesn't go mouldy from the inside out.
All four ways of working differ in a single factor: how much water the material is allowed to see.
On a car seat, the answer is barely damp. The cleaner goes onto the sponge and never directly onto the leather, the foam carries the loosened dirt, and a damp cloth takes both off again. Spray onto the leather instead and you drive moisture into seams and perforation, where it stays for days.
With sneakers, the tool takes care of the dosing. The foam from the 200 ml dispenser is pumped onto the damp brush or sponge, not onto the shoe. The reason is down to how the shoe is built: the midsole glue is water-based, and once the upper is saturated, water runs into the seam and the sole starts to come away from the shoe. Micro-foam instead of free liquid isn't about convenience here — it's insurance for the material.
Machine washing is the only case where leather can go fully under water — and only because the fixative bath has locked in the pigments beforehand. 5 to 10 litres of lukewarm water, 60 minutes' soaking time, a quick move around every quarter of an hour. Then the item goes into the drum damp and without rinsing.
On a convertible roof the rule flips: lots of water is a must there. After brushing it clean, keep rinsing with clean water until it runs off foam-free. Cut that short and four weeks later you'll be having a debate about how long the sealant lasts that's really a debate about the rinse.
The common thread is unspectacular, but it carries all four uses: you control the amount of water with the tool, not the bottle. That's exactly why every box includes the right tool.
The step that's most often missing isn't a step at all. It's the break between cleaning and caring.
The dwell times themselves are short and similar across the board: 5 to 10 minutes, during which the cleaner works and must never dry on. Then the waiting starts. A cleaned leather seat needs a good half hour at room temperature before care makes sense. A roof needs several hours, ideally overnight. Sneakers dry at room temperature with shoe trees — no heater, no hairdryer, no sun.
The second wait comes at the end. The textile sealant from the Cabrio set cures for 24 hours and wants to stand at between 10 and 40 degrees while it does; the protector from the set for new leather needs twelve to 24 hours and no blazing sun. With the sneaker set, the application window is between 15 and 25 degrees — in the cold the foam won't wipe off properly, in the heat it dries on too soon.
So don't plan the job in working time, plan it in calendar time. From day-to-day at Detailing1 we know exactly one type of complaint about sets, and it starts on a Saturday morning: clean, quick wipe, care straight away, gone by the afternoon. Two thin applications a year are more than enough for well-kept leather — and both can be spread over two days.
Drying leather clothing has its own rule, because heat changes the material permanently. Working it through by hand when half-dry, or fluffing it up in the dryer on cold air, keeps the fibres supple. Heater air and sun drive out residual moisture too fast and leave an item that feels like someone else's the first time you wear it.
A set is calculated for one single item and the two sessions a year it needs. Beyond that, the maths flips.
As soon as a second and third car are on the list, or you detail commercially, litre containers pay off. You then set the pairing once yourself and work through it the same way every time. The components are available separately: the matching care under Leather care from COLOURLOCK, the matching cleaner under Leather cleaner by COLOURLOCK. The same goes if you've already got a tried-and-tested cleaner on the shelf and only need the care.
The sneaker set has a clear upper limit, and we'll say it openly: it's care for good shoes, not a reset for trodden-in mud. Deep-seated road grime, winter salt marks or oil stains go beyond its mild cleaning power — for those you need the stronger formulas from Shoe & sneaker cleaner by COLOURLOCK. Buy the set for your everyday sneakers in November rain and you'll be disappointed.
The Wash Set has its no-gos too, and they're non-negotiable. Open-pored aniline leathers soak the wash solution straight into the fibres, furs with a wash-out tannage lose their structure, and fitted car seats don't go in the machine anyway. With the Cabrio set, the most common false expectation we see is a different one: it cleans and seals, it doesn't dye. A faded grey roof comes out clean and water-repellent after treatment, but it won't turn black.
The last limit applies to all sets equally. None of them repairs. Once the top coat on the side bolster is worn through or the colour has cracked, no amount of conditioner helps — only colour does, and that's a job for Repair by COLOURLOCK. Care keeps the condition you've got — it doesn't bring back one you've lost.
The choice comes down to two questions, and the first is basic: what are you holding in your hand?
If it's fitted car leather, the first cleaning pass gives you the answer. Take a damp sponge with a little cleaner and work a palm-sized area somewhere hidden. If only grey dirt comes off on the sponge and the area stays even afterwards, the finish is intact and a gentler set will do. If the spot dries dull and drinks up the first care straight away, the leather has aged and needs the richer conditioning. If, on the other hand, the sponge picks up the leather's colour, the top coat is already open — and then a care set isn't the next step. The three stages for the first two cases are in the Leather-age care kits by COLOURLOCK, with the set for aged smooth leather being the one we're asked about most.
If it's removable — leather jacket, motorcycle leathers, seat cover, sheepskin — the way to go is the COLOURLOCK "Leather Wash Set" with its pre-soak. If it's sneakers made of mixed materials, the COLOURLOCK "Sneaker Cleaner Set" is the right choice. If it's a fabric roof, reach for the COLOURLOCK "Cabrio Care Set", the only one in this series that works with fabric rather than leather.
Two cases fall outside this series. Open-pored aniline and nubuck leather needs its own products instead of a standard set, and if you're only after one part of the routine, single containers will serve you better. You'll find all the brand's other combinations, from repair to colour sets, one level up: Back to Sets from COLOURLOCK.
And the line no box comes with: don't plan the work, plan the waiting. A complete interior is cleaned and cared for in a good hour, but the drying phases in between take several times that. Unpack the set in the morning wanting to be done by lunchtime and you'll make the one mistake no formula can catch — no matter which of the sets is sitting on the table in front of you.
