It simply doesn't get any cleaner or better than this.

We guarantee it!

We claim to be the cleanest all-around cleaning company in the country.
And we live up to that claim every day. Our clients can attest to that. Will you be next?

From Office Cleaning to Crime Scene Cleaning

At 12B Clean, we don’t shy away from anything—and I mean absolutely anything—when it comes to cleaning. Our three divisions are staffed by intelligent and highly trained people who know exactly what is expected of them.

The Workers are experts in all standard cleaning tasks. Offices, schools, vacation parks, commercial buildings, student housing, etc., are their daily work environment. The Masters are trained for more specialized and demanding cleaning tasks. The Profs , finally, are trained for highly specialized work, such as crime scene cleaning at the sites of murders, crimes, deaths, and suicides, as well as handling cadaveric odors, trauma, and biohazards. They, too, are on call 24/7 to provide immediate assistance anywhere in the Netherlands.

We'd like to get started working for you

Nice to meet you. We are Jack Oosterwaal and Michael de Bruine, both founders of 12B Clean. We’ve known each other for years and are inseparable in business. We once shared a dream: to start our own company in the cleaning industry—one that we wanted to run much better, much more comprehensively, and with a much more human touch than any other company.

If that’s what you want, that’s what you should do. Here’s the result. Our employees are well compensated, receive training and recognition, and go to our clients with certifications in hand. Those clients value intelligent and skilled people on their work floors. Together, we’re experts in every cleaning market—from routine cleaning to extreme cleaning tasks. And all of this at a highly competitive price. With good organization, this is a win-win model for everyone involved.

Shall we set up an appointment?
