For anyone who cleans vessels and lines in paint, coating and ink
"One trace of old paint can ruin a whole new batch. This free guide shows you how to get everything truly clean, faster and cheaper"
A free guide from our own lab. For every type of paint and ink: what dissolves it, how to rinse, and how to switch colours fast without throwing anything away.
(This is what we see in our own lab every week)
100% privacy. No spam. No calls.
Same machine, different chemical


Left: dried-on old colour. Right: the same wall, ready for the new batch.
Why your next charge comes out pink (and it is not the paint)
There is still a smear of red on the wall. The vessel has to run. The white charge goes in.
And it comes out pink. That is not a scratch in the paint. That is 8,000 litres of reject over one trace of pigment.
To stop that, you chase thinner through the line for an hour. It still runs back coloured. More thinner is not the answer. It is only more fumes and more waste.
And the resin you let dry in yesterday? It is on the plan today as a scraping job. Someone gets to climb into the vessel with a scraper. Every stroke is a scratch.
That is only step 1 of the plan. Below you can see where the colour hides as well: in the line, in the nozzle, in the filter.

What is in it for you?
Faster changeover
Less time lost between two colours. Every minute is a minute more production.
No failed batch
A clean final rinse keeps the last colour out of the next one. That saves scrapped product.
Less solvent
Alkaline where you can, solvent only where you must. Cheaper, safer and less waste.
Vessels stay sound
Soak loose instead of forcing. That way you do not attack the wall and your gear lasts longer.
The plan: each step hits a spot where the colour hides
Everyone thinks: if colour still comes out, I chase more thinner through it. But the residue does not leave because of more litres. It leaves because of the right agent on the right type of residue. Water based, thinner based, resin and pigment each need something different. One agent for everything is the reason you are still rinsing after.
We make cleaning chemicals for factories, in our own lab. There we see the same thing every week: almost every line leaks money in the same spots. The smear in the blind corner of the vessel, the shadow in the last few metres of line, the hole in the nozzle, the filter that clogs. That plan is now in a free guide. In plain words. Per step it says: which agent, how strong, how long, and how you see that it is done.
Inside the guide you will find:
- Step 2 of the plan: which residues you soak loose with a soap agent, instead of chasing thinner through the line for an hour. On most residues that saves fumes and a heap of waste.
- Step 4: how you get the shadow of the last colour out of the final metres of line before the light colour goes in. That is the spot no one checks, and where the pink charge begins.
- Step 6: how you let hard resin soak loose, so no one has to climb into the vessel with a scraper and the wall stays sound. Plus the soak time that lets it release without you standing over it.
- Step 8: why your machines suddenly run crooked or uneven from dried paint or ink in the small holes, and how you flush that loose from the inside without stripping everything down.
- Step 10: the check that tells you the line is truly clean. Catch some rinse water and hold it up to the light. If you still see a tint, colour is still in there. This is exactly where people stop too soon and lose the white charge.
- Step 12: the first ten minutes after the batch. What you pre-rinse now is not on the plan as a scraping job tomorrow. Plus which residues are fine to let wait a bit.
What the people who tried it say
Our customers are paint, coating and ink factories all over the Netherlands. We keep their company names private, that is part of doing business. You may read their words.
“We chased thinner through the line for an hour at every change. Turned out half of it was not needed. On most residues their soap agent does the work. Saves fumes and a lot of waste.”
“They did not show up with a folder. They asked: send us your dried ink. Two weeks later there was an agent made for our own grime.”
“We always let the resin layer cure. Then someone had to go in with a scraper. Since we pre-rinse right after the batch, I soak it loose. No more scratches on the wall.”
“I thought: another supplier. But the rinse water came back truly clear for the first time. The white charge after it passed just fine.”
“Our nozzles kept spraying crooked. Stripping them down every time. Now I flush the build-up loose from the inside. The line does not just drop out anymore.”
“Half an hour on the phone, and I had an approach I could run with myself. Only became a customer months later. Nobody called me back to chase it.”
An honest letter from the our lab bench
Dear professional,
We are a Dutch factory. Our place smells of chemistry. We make cleaning chemicals, every day, for years.
Every week people send us their grime. A coupon with dried ink film on it. A tub of cured resin. Pigment lodged in the rim of a manhole. In our lab we work out which agent gets it loose. That is our trade.
And in all those years we kept seeing the same thing. Factories reject batches and chase hours of thinner away. Not because their people work badly. But because one agent is used for every type of residue, and because the eye trusts the wall too soon.
We always gave that knowledge away to customers. Now we put it in a free guide, for everyone.
Why free? Simple. We hope that after reading you think: if their free guide is this good, what would their chemical do? That is our whole business model. Now you know the motive, and you can read the guide in peace.
The Cleanline teamOur own factory and lab
Honest: our chemical is often not the cheapest per litre.
We are open about that. A drum from us sometimes costs more than the drum you work with now.
But you do not pay per litre. You pay per colour change. And per charge you do not have to reject. A chemical made for your ink and resin gets the last colour out faster, with less thinner.
Do the math. One rejected white charge of 8,000 litres costs you many times a drum of cleaner. One colour change that goes from two hours to one, several times a day, is half a production shift a week regained. Then you know what the lowest litre price really costs.
That is why we let you test for free first. Your own numbers convince better than we do.
How one customer did it
An ink maker in Brabant halved the time between two colours
A factory that makes printing ink ran the step plan. They pre-rinsed right after the batch, instead of later. And they soaked the residues loose instead of staying on and scrubbing. The final-rinse check became a fixed part of every changeover. Do the math: a colour change from two hours back to one, several times a day, is half a production shift a week regained.
“We thought more solvent was the answer. It was in the order. Pre-rinse on time and rinse out properly. That was all.”

To be honest: we are a factory, not a call centre. Our lab people make each test sample themselves, on your ink or paint. So we only do a few a month. When full, it is full.
Our guarantee, in black and white
Test our chemical? If it does not get your vessel at least as clean as your current one, with the same or less solvent, we make a new formula for free. As long as it takes to get it right.

The products that go with this
Questions we hear a lot
Solvent works, but it is expensive, it gives VOCs and waste, and your people breathe it in. Many residues also emulsify with an alkaline, water based cleaner. Then you keep solvent only for the residues that truly need it. The guide shows where that difference sits.
Yes. The wall can be clean while the nozzle sprays crooked and the filter clogs. The guide shows how you circulate through lines, nozzles and filters, so you soak the build-up loose from the inside instead of stripping it out or breaking the filter pack loose.
You do not have to. You tell us which residues stay behind. Our lab makes the sample for your ink or resin. You run one cleaning and check if the rinse water comes back colourless. That is all we ask.
That is why material compatibility comes before the cleaning. Too high a concentration or too aggressive an agent attacks the passivation and plastic. We test on your material before it goes into your line, and soaking loose does less damage than scraping. The guide explains how you check that.
Nothing. The guide is free, the test sample too. You are tied to nothing. You read the guide, you test what you want, you decide. We only earn when you become a customer later.
P.S. Still in doubt? Reading the guide takes you 15 minutes. One rejected charge costs you many times that. And most teams win time right at the first colour change. Doing nothing costs you those same litres of reject and those same hours of scraping, every changeover again.
P.P.S. You get the guide straight in your inbox. No calls after. We supply companies, so we only ask for your email and your company name.
