Concrete floor cleaning for commercial buildings: how it's done and when it's time to seal

A mop can't fix a floor that's gone gray and dull. Here are the signs it's time for machine work, how oil gets out, where sealing fits, and one café floor from dull to glossy.

Professional commercial concrete floor cleaning starts with sweeping and pre-treating oil, then scrubs the floor with a machine and a pad or brush matched to the concrete. The dirty water is extracted and rinsed, not mopped around. Heavy buildup takes more than one pass, and a floor that stays dull afterward usually needs to be stripped, degreased and sealed.

Texas Industrial Cleaning Services is a commercial cleaning company serving the Dallas–Fort Worth Metroplex. We provide office cleaning, commercial floor cleaning (including stripping and waxing), and recurring janitorial services for offices, medical and dental practices, and multi-tenant buildings across Dallas, Tarrant, Denton and Collin counties.

What does professional concrete floor cleaning involve?

It involves sweeping, pre-treating oil, machine scrubbing, extracting the dirty water, and letting the floor dry. This is how the work is generally done on commercial concrete:

  1. Dust-mop or sweep so grit isn't ground into the surface.
  2. Pre-treat oil and grease spots with a degreaser and give it time to work, per the label.
  3. Scrub with an autoscrubber or rotary machine, using a pad or brush matched to the floor. Textured or porous concrete usually calls for a brush.
  4. Extract the dirty water and rinse, so the soil leaves the building instead of drying back into the pores.
  5. Neutralize if a strong alkaline product was used.
  6. Let the floor dry completely.

Years of buildup rarely come up in one pass. Expect a second pass on the worst areas.

When does in-house mopping stop working on commercial concrete?

Mopping stops working when the floor looks dirty again soon after being mopped. Concrete is porous, so a mop pushes dirty water into the pores and leaves a film behind rather than lifting soil out.

The usual signs:

  • A gray film that returns after every mopping.
  • A dull, matte look where traffic is heaviest, even when the floor is clean.
  • Soil visibly worked into the pores of the surface.
  • Oil tracked from one area into the next.

The same applies to warehouse concrete: it's a hard, porous surface, and it responds to machine scrubbing and extraction in the same way.

How do you get oil and grease out of commercial concrete?

Oil comes out of concrete with an alkaline degreaser, time and a machine scrub. Spraying and wiping doesn't work because the oil has soaked below the surface.

Degreasers need dwell time, and the manufacturer's label sets how long. After the dwell, the area is agitated with a brush or pad and the residue is extracted. Fresh spills lift easily. Old stains are different: oil that has sat for years may lighten rather than disappear.

Should a commercial concrete floor be sealed?

Sealing is worth considering when concrete is porous, stains easily or is hard to keep clean. A sealed floor is generally easier to keep clean than a bare one.

Before a sealer goes down, the floor has to be clean and degreased. Sealers wear in traffic lanes, and commercial concrete is typically resealed every 3 to 5 years.

We strip, degrease and seal concrete. We don't grind it. Diamond grinding and polished-concrete installation are a different trade, and if you want a ground-and-polished slab, hire a contractor that does that work.

What did a real concrete restoration look like?

A café's roughly 2,000 sq ft of dull concrete went from matte to glossy with a three-step strip, degrease and seal.

This was one of our own jobs, covering the café's concrete floors from the dining room to the sales floor. There was no grinding: the existing slab was stripped, degreased and resealed with an all-in-one sealer and finish coat, and it came out glossy and reflective. The photos on this page are the same rooms.

How often does commercial concrete need cleaning?

Commercial concrete should be deep-cleaned every 6 to 12 months and resealed every 3 to 5 years. Traffic, how much soil and oil the floor sees, and whether it's sealed decide where a floor falls in that range: an unsealed floor in a high-traffic or greasy area needs it sooner.

Between machine cleans, daily dust-mopping and damp-mopping or autoscrubbing keep grit off. Concrete follows a different rhythm than a finished tile floor, which has its own strip and wax cycle. The deep-clean interval is set at the walkthrough, based on how the floor is actually used.

What affects the cost of cleaning and sealing concrete floors?

Scope is the biggest driver, meaning what the floor needs, from a scrub to a full strip, degrease and seal. After that:

  • Square footage. Bigger floors cost more in total.
  • Condition. How worn or soiled the floor is now.
  • Sealed or unsealed. An existing sealer may need to come off first.
  • After-hours access. Work around business hours changes the schedule.

A floor like the café on this page, about 2,000 sq ft of concrete that needed a three-step strip, degrease and seal, typically runs $1,500 to $2,000. Scope decides where a floor lands, and a free on-site walkthrough sets the exact price.

Common questions

How do you clean a commercial concrete floor?

The floor is swept, oil spots are pre-treated with a degreaser, then it's scrubbed by machine with a pad or brush matched to the concrete. The dirty water is extracted and the floor is rinsed and left to dry. Heavy buildup usually needs more than one pass.

How often should commercial concrete be deep-cleaned?

Commercial concrete should be deep-cleaned every 6 to 12 months and resealed every 3 to 5 years. Heavy traffic, oil and grit push a floor toward the shorter end. The exact interval is set at the walkthrough, based on how the floor is actually used.

How do you remove oil stains from a warehouse concrete floor?

Fresh spills lift easily. Older stains get an alkaline degreaser left on for the dwell time on its label, then a machine scrub and extraction. Old oil that has soaked deep may lighten rather than disappear.

Do commercial concrete floors need to be sealed?

Not every one does, but sealing is worth considering on a floor that is porous, stains easily or is hard to keep clean. The floor has to be clean and degreased before a sealer goes down. Sealers wear with traffic, and a commercial floor is typically resealed every 3 to 5 years.

How much does it cost to clean and seal a commercial concrete floor?

A floor like the café on this page, about 2,000 sq ft of concrete that needed a three-step strip, degrease and seal, typically runs $1,500 to $2,000. Scope decides where a floor lands, and a free walkthrough sets the exact price.

Is cleaning concrete the same as polishing it?

No. Cleaning, stripping and sealing treat the surface that is already there, while polished concrete is installed by grinding the slab with diamond tooling, a different trade. We don't grind or polish concrete.
