Why your grout went dark in the first place
Glazed tile is essentially sealed glass — almost nothing sticks to it permanently. Grout is the opposite: it is cement, it is full of microscopic pores, and it sits about a millimetre lower than the tile, which makes every line a small channel that collects everything on the floor.
Then there is mopping. A mop lifts the loose dirt off the tile, dissolves it into the bucket water, and pushes that dirty water directly into the grout lines, where it dries. Repeat that weekly for four years and the grout is not stained on the surface — it is loaded with soil several millimetres deep. That is why scrubbing a line with a brush and a bathroom spray gets you a slightly lighter line and a very sore back. You are cleaning the top of a problem that goes down.
What I actually do
The process is genuinely different from carpet work, and the machine is the reason it works:
- Sweep and inspect. I check for cracked, missing or crumbling grout first. Blasting pressurized water at a failed grout line pushes water under the tile, so anything loose gets flagged before I turn anything on — that is a repair, not a cleaning.
- Alkaline pre-treatment. A cleaning solution goes down and is given real dwell time to break down grease and body soil. This is the step most people skip, and it is the step that does most of the work.
- Agitate the lines. The corners, edges and worst lines get worked by hand. A machine head cannot reach into a corner or up against a toe-kick.
- Pressure rinse with recovery. A closed spinner tool sprays hot water into the floor under pressure and vacuums it straight back out inside the same housing. The dirt leaves the building in my tank instead of being spread into the next room. It also means there is no flood, no squeegeeing, and no dirty water sitting in your lines afterwards.
- Neutralize and dry. A final rinse pass so no cleaning residue is left behind to attract dirt, then I towel the edges and thresholds.
Drying time
Tile is the fastest floor I clean. The surface is usually walkable in 30 to 60 minutes and fully dry within a couple of hours. Grout holds moisture a little longer, which matters only if you are sealing — see below. This is why an evening appointment makes so much sense for a kitchen: I finish at 8pm and the floor is normal before you go to bed.
What comes out, and what does not
- Comes out: general soil and greying, kitchen grease, cooking oil film, soap scum, hard-water film on floor tile, mildew staining in bathroom lines, and the dark halo that builds up in front of a sink or stove.
- Sometimes comes out: rust marks, mop-water staining that has set for years, and dye from a rubber-backed mat. These depend on how deep it went and how long it has been there. I will give you an honest read before I quote.
- Does not come out: grout that has been dyed or stained by a colorant, etched or scratched tile glaze, cracked and missing grout, and efflorescence caused by an active moisture problem underneath the slab. Efflorescence in particular will come straight back, because the cause is water rising through the concrete — cleaning it is treating a symptom.
The honest expectation: grout usually comes back several shades lighter, close to its original color. It does not come back white unless it started white and the damage is only soil. If you want a uniform, brand-new color across a floor with patchy or dyed grout, the answer is color-sealing, not cleaning — and I will tell you that rather than take your money twice.
Sealing — worth it, but only after cleaning
A penetrating sealer soaks into the grout and makes it repel water and oil for a couple of years, so spills sit on top long enough to be wiped up instead of soaking straight in. It is the single best thing you can do to keep a floor looking clean, and it is the reason your grout was light-colored for the first year after the tile was laid.
Two rules. Sealer must go on clean, dry grout — sealing dirty grout permanently locks the dirt in, which is why I will not do it in the same hour as the cleaning. And grout needs to be properly dry first, so sealing is usually a short return visit the next day or later the same week. If someone offers to clean and seal your floor in one 90-minute appointment, they are sealing wet, dirty grout.
Where this is usually worth doing
Kitchens and entryways get the most dramatic results, because they collect grease and outdoor grit respectively. Bathrooms are next — particularly the floor around the base of a toilet and the lines in a shower pan. Laundry rooms and the tile strip inside a garage door are the two people forget. If you have tile through a whole ground floor, that is where the price per square foot drops the most, so it is worth doing it all in one visit.
Tile & grout pricing
Tile is priced by the floor rather than by the room, because a 40-square-foot bathroom and a 400-square-foot kitchen are not the same job. Condition matters as much as size — a floor that has been mopped weekly for ten years takes longer than one that was sealed two years ago.

Send me a photo of the floor and a rough square footage and you will get a firm number back, usually within the hour. If I am already coming out to clean carpet, adding a kitchen or bathroom floor to the same visit is always cheaper than booking it separately — the setup is already paid for.
