"Clean" is not something you can hold anyone to. Here is what to ask for instead of a walk-through.

"The office is clean" tells you nothing you can act on. It is an impression. It changes depending on who is looking and what kind of week they are having. And it gives you no way to get anything fixed.

When you buy hours of labour, you take on the job of deciding — every single week — whether those hours produced a result. The standard has to live somewhere outside your own head. Otherwise you are the standard, and nobody signed up for that job.

So: who owns the standard, and how do you find out before you sign?

Why Looking Around Does Not Work

Most offices get judged by eye. The front desk shines, the bins are empty, the impression is good.

The problem is not that looking is useless. It is that looking only checks the things that were going to get done anyway, because they are the things anyone can see. Grit deep in the carpet, film left on a door handle, a disinfectant wiped off before it had time to work — all three pass a walk-through perfectly.

That is not a reason to measure everything. It is a reason to know which parts of the job your eyes cannot check, and to ask how those parts get controlled.

There is a tool that measures one part of it. You wipe a surface with a swab and put the swab into a small reader. The reader looks for a chemical called adenosine triphosphate, or ATP. Every living thing has it, so a high reading means there is still organic material sitting on the surface. It is used in restaurants and hospitals, and it is genuinely useful for one thing: showing whether a surface actually got cleaned.

It is worth being clear about what it does not do, because the industry is not. ATP does not tell you a surface is safe, and it does not find germs. It finds leftover organic material, which is a clue about how well the cleaning went. The pass-or-fail number is different on every brand of reader, so you cannot compare one company's number to another's. And a person still decides where to swab, which is a judgement call no machine takes away. Anyone selling ATP as proof that your office is safe is overselling a real tool.

How to check: if a company offers this, ask what number counts as a fail, on which reader, who picks the spots, and what happens to a surface that fails. Those answers tell you whether it is a real control or a sales prop. If a company does not offer it, that is not a mark against them — most offices do not need it. The question is what else they use to check the parts nobody can see.

Moving Germs Around Is Not Cleaning

One cloth wiped across a washroom and then across the break room does not remove anything. It moves it.

Nobody argues about this, and it needs no study. It is the reason the whole industry uses colour-coded cloths. Washrooms get one colour, general surfaces another, glass another. A cloth never leaves its zone.

What makes it work is not the colour. It is everything around it: the rule is written down, staff are trained on it, and the cloths are kept apart in the cart so that following the rule is easier than breaking it. A colour code that lives only in a sales pitch is decoration.

Microfibre is the standard cloth for this, and it does pick up more germs than cotton. You will see a specific pair of numbers quoted a lot in this business — 99% versus 30%. Those numbers come from a test of floor mops, and they get repeated mostly by companies that sell cleaning supplies. The basic point holds up. But the numbers describe mopping a floor, not wiping a desk, and anyone quoting them at you about desks either has not checked or is counting on you not to.

Then there is the part nobody puts in a brochure, because it is boring. Every disinfectant has a wait time printed on the label. That is how long the surface has to stay visibly wet for the product to do what the label says. Wipe it off after fifteen seconds and it does not half-work. You have cleaned the surface and skipped the disinfecting entirely.

It is one of the most commonly skipped steps in this trade. It costs nothing to do right. And afterward, there is no way to tell by looking whether anyone waited.

How to check: ask which product goes on which surface, how much water it gets mixed with, and how long the label says to leave it wet. Then ask how anyone knows the crew waited. There is no perfect answer to that last one, which is exactly why the answer tells you something.

Every Surface Has Rules, Written Down or Not

Your building has floors, fixtures, counters, glass and furniture, and they all handle chemicals differently. Too acidic on stone, the wrong product on a coated surface, the wrong pad on a finish — none of these look like a problem that day. They shorten the life of the material, and years later it turns into a big bill nobody connects to a cleaning decision.

Preventing that takes a simple table: which product, how much water, which tool, which surface. Nothing about it is complicated. What matters is whether it exists on paper that the crew follows, or only in the head of whoever has been there longest — because that person will eventually leave, and the knowledge leaves with them.

How to check: ask for the table. If it exists, they can send it the same day, because their staff already use it. If it does not, someone is deciding at the sink with the bottle in their hand. And if the wrong product goes on your new counters, nobody will ever be able to tell you whether that was a mistake or just what they always do. The risk is not the damage. It is that you can never find out what caused it.

Three Documents, and What It Means When They Are Missing

• The written standard. Not a to-do list. A description of what a room should look like when the work is done. A to-do list cannot be broken: if all you agreed on is that someone would vacuum, then on the day the room is wrong, nobody did anything wrong.

• The routine and the training record. Colour codes, wait times, order of work — plus proof staff were trained and someone checks. Ask what happens when a task gets missed, and ask to see a filled-in record from a real building, not a blank form.

• Proof of coverage. WorkSafeNB registration and liability insurance are the law, not an achievement. What matters is that the numbers are real and you can look them up. Watch out for badges that sound official. Some are home-cleaning memberships anyone can buy, and they tell you nothing about office work.

When these do not exist, the missing paperwork is not really the problem. The problem is that quality is being carried around in somebody's head. That means it changes when the staff changes, and the change lands on your calendar, not theirs.

But Does This Not Cost More?

Written systems sound expensive, and plenty of offices honestly just need the bins emptied and the floors done.

But the paperwork itself is cheap. The surface table is a table. The colour code is three colours. The wait time is printed on the bottle. What actually costs something is the discipline to follow all of it when nobody is watching — which is exactly the thing you are buying, and exactly the thing you cannot check by walking around.

A company that has written none of it down is not offering you the same service for less. They are offering a service that only stays steady if their staffing stays steady, and staffing is not something you control. Then they hand the checking back to you. That difference is worth putting a price on, and you can price it against any quote already on your desk.

Which brings it back to the point from What a Commercial Cleaning Company Should Never Promise You. The question was never whether cleaning makes your team better. It is whether cleaning stops being something anybody has to manage.
