Concrete is the most common commercial floor surface in Canada — warehouses, industrial facilities, commercial kitchens, parking structures, gyms, and arenas all rely on it. But concrete's porosity and surface texture make it one of the more demanding floors to maintain. Using the wrong cleaner, the wrong dilution, or the wrong protocol can etch the surface, leave residue, or simply fail to remove embedded soil.

This guide covers the complete selection and application process for commercial concrete floor cleaning — from soil type identification to cleaner formula selection, dilution ratios, and maintenance scheduling by facility type. JANITORI™ [Floor Cleaner No.61](/products/floor-cleaner-janitori-no-61) is a plant-based concentrate manufactured in Canada since 1994, designed for commercial and industrial concrete floor applications. Available in 4L ($29.95) and 20L ($199.95).

 **Key Takeaways**
- Concrete floor cleaners should run pH 7–10 for daily maintenance and up to pH 12 for degrease cycles on unsealed concrete — cationic surfactants and highly acidic cleaners both damage sealed and unsealed surfaces over time.
- JANITORI™ Floor Cleaner No.61 dilutes from 1:10 for heavy degreasing up to 1:50 for daily maintenance, with a 4L jug making up to 200L of ready-to-use solution.
- Rinsing after every wash is mandatory on concrete — leftover concentrate residue acts as a soil magnet and is the top cause of floors that look dirty again within days.
- Switching a 1,000 sq ft concrete floor from RTU cleaner to concentrate saves an estimated $423–$1,203 per year in product cost alone, before labor savings from fewer refill trips.

## Why Does Concrete Need a Different Floor Cleaner Than Other Surfaces?

Concrete's porosity and surface texture react differently to pH, surfactant type, and dilution than sealed hard floors like tile or vinyl — a cleaner that's safe on ceramic can etch unsealed concrete or degrade a sealer coating.

Polished, sealed, and unsealed concrete each behave differently during cleaning. Unsealed concrete is highly porous — it absorbs oils, grease, and cleaning chemicals if the wrong pH or concentration is used. Sealed concrete is more forgiving but requires pH-neutral to mildly alkaline cleaners to avoid degrading the sealer coating over time. Polished or epoxy-coated concrete is the most durable but still sensitive to highly acidic or highly alkaline products.

The key parameters for concrete-compatible floor cleaners are:
- **pH range:** 7–10 for general maintenance; up to 12 for degrease cycles on unsealed concrete
- **Surfactant type:** Non-ionic or anionic — cationic surfactants can leave sticky residue on concrete
- **Dilution ratio:** Critical — over-concentration increases residue and sealer damage risk
- **Rinseability:** Concentrate residue on concrete attracts soil faster; full rinse after cleaning is essential

## What Types of Soil and Stains Show Up on Concrete Floors?

Concrete soil breaks into seven common categories — grease, tire marks, general dirt, food residue, carbonized grease, efflorescence, and biological growth — and each one calls for a different cleaner chemistry.

 | Soil Type | Facility Source | Cleaner Required

 | Grease and oil (fresh) | Commercial kitchens, warehouses, garages | Alkaline degreaser or APC concentrate

 | Tire marks and rubber transfer | Warehouses, loading docks, parking | Alkaline concentrate; mechanical scrubbing

 | General dirt and dust | All facilities | Neutral to mildly alkaline APC concentrate

 | Food spills and organic residue | Cafeterias, food processing, arenas | Alkaline APC concentrate

 | Carbonized grease (baked-on) | Commercial kitchens, food service | Heavy-duty degreaser only

 | Efflorescence (white mineral deposits) | Exterior concrete, basements, loading areas | Mild acid cleaner (NOT alkaline APC)

 | Biological (mould, mildew) | Arenas, locker rooms, wet areas | Disinfectant — DIN-registered; clean first

**Important:** For carbonized grease on commercial kitchen floors, use a dedicated degreaser rather than an all-purpose floor cleaner. [Industrial Degreaser No.71](/products/degreaser-janitori-no-71) is specifically formulated for carbonized grease deposits in commercial kitchen environments. See: [Commercial Kitchen Hood Degreaser: The Professional's Cleaning Guide](/blogs/the-clean-room/commercial-kitchen-hood-degreaser-guide).

## Which Floor Cleaner pH Range Is Right for Your Concrete?

Match the cleaner's pH to your concrete's finish and soil level: neutral for polished or decorative slabs, mildly alkaline for routine commercial maintenance, and high-alkaline only for heavy industrial degreasing.

## Neutral All-Purpose Concentrate (pH 7–8)

For daily or routine maintenance cleaning of sealed or polished concrete. Minimal sealer interaction. Works on general dirt, dust, and light organic soil. Best for high-traffic offices, hotel lobbies, and retail floors with decorative concrete or polished slab.

## Mildly Alkaline Concentrate (pH 8–10)

The primary choice for most commercial concrete floor maintenance. Handles grease films, body oils, food residue, and tire scuff on smooth and broom-finished concrete. Safe for most sealed concrete when used at recommended dilution. JANITORI™ Floor Cleaner No.61 operates in this range.

## High-Alkaline Degreaser (pH 11–13)

For heavy industrial concrete — loading docks with oil-soaked concrete, commercial kitchen floors with grease buildup, or unsealed warehouse floors with embedded petroleum-based contamination. [Degreaser No.71](/products/degreaser-janitori-no-71) handles these applications. Not for daily use on sealed concrete — pH can degrade sealer over time. Products in this pH band typically meet WHMIS's [corrosive-materials hazard classification](https://www.ccohs.ca/oshanswers/chemicals/corrosive/corrosiv.html), so gloves, eye protection, and controlled dilution are required for safe handling.

## How Do You Clean a Concrete Floor Step by Step?

Dry sweep first, pre-treat heavy stains, mop with a correctly diluted solution in sections, then always rinse and allow the floor to dry fully before returning it to service.
- **Dry sweep or vacuum:** Remove loose debris, dust, and particulate before wet cleaning. Wet mopping over sand and grit abrades the floor and clogs mop fibres.
- **Pre-treat stains:** Apply concentrate directly to oil spots, tire marks, or heavy stains. Let dwell 2–5 minutes before mopping. Do not let the concentrate dry on the surface.
- **Prepare diluted solution:** Mix at recommended dilution ratio in a clean bucket. Change solution when it becomes visibly dirty — mopping with dirty water deposits soil rather than removing it.
- **Mop in sections:** Work in manageable sections (50–100 sq ft), overlapping strokes, wringing the mop frequently. For auto-scrubbers, use the concentrate at the recommended machine dilution (typically 1:50 or lower for autoscrubber tanks).
- **Rinse:** Follow with a clean water rinse mop or autoscrubber recovery pass. Concentrate residue on concrete attracts and holds future soil faster — rinsing is not optional for commercial floors.
- **Allow to dry:** Ensure adequate ventilation and drying time before returning the area to service. Wet concrete is a slip hazard — the [Canadian Centre for Occupational Health and Safety (CCOHS)](https://www.ccohs.ca/oshanswers/safety_haz/falls.html) lists wet floors among the leading contributors to same-level slip-and-fall injuries in workplaces — and adequate dry time reduces that risk while limiting soil re-deposition.

## What Dilution Ratio Should You Use for Concrete Floors?

No.61 runs from 1:50 for light daily maintenance up to 1:5 for spot degrease treatment — the heavier the soil, the more concentrate, but over-diluting wastes labor and under-diluting wastes product and adds residue risk.

 | Application | Soil Level | No.61 Dilution | Notes

 | Light maintenance | Dust, light soil | 1:50 | Daily sweep-and-mop; autoscrubber tank fill

 | General maintenance | General dirt, food residue | 1:20 | Standard twice-weekly cleaning cycle

 | Heavy cleaning | Grease films, tire marks | 1:10 | Weekly deep clean; pre-wet heavy stains

 | Degrease pre-treatment | Embedded grease spots | 1:5 (spot treatment) | Dwell 5 min; scrub; rinse thoroughly

## How Often Should You Clean Concrete Floors by Facility Type?

Cleaning frequency for concrete ranges from daily at commercial kitchen close to weekly for warehouse floors — traffic volume and soil type set the schedule more than the facility category itself.

 | Facility Type | Floor Type | Frequency | Protocol

 | Warehouse / distribution | Sealed or unsealed concrete | Weekly (sweep daily) | 1:10 dilution; autoscrubber or mop+rinse

 | Commercial kitchen | Quarry tile or unsealed concrete | Daily at close | 1:10 + degreaser spot treatment; rinse thoroughly

 | Gym / arena | Sealed concrete or rubber over concrete | Daily (high traffic); weekly deep | 1:20 daily; 1:10 weekly; rinse required

 | Hotel / hospitality | Polished or epoxy-coated concrete | Daily (high traffic areas) | 1:30 to 1:50; avoid over-concentration on polished surfaces

 | Office / retail | Sealed or decorative concrete | Daily sweeping; weekly wet mop | 1:30; autoscrubber preferred for large areas

 | Loading dock | Rough or unsealed concrete | Weekly minimum; as-needed for spills | 1:5 to 1:10; pre-treat oil/grease deposits; hot water beneficial

## How Much Does Cleaning a Concrete Floor Actually Cost Per Use?

A concentrate like No.61 costs roughly $0.15–$0.37 per litre of ready-to-use solution depending on dilution, versus $2–$5 per litre for typical RTU floor cleaners — an annual difference of hundreds of dollars per 1,000 sq ft of concrete.

The cost-per-litre advantage of concentrates is substantial compared to RTU floor cleaners. For a 1,000 sq ft warehouse floor requiring approximately 5 litres of solution per mop session:

 | Product | Dilution | Cost/L RTU | Cost per 5L mop session | Annual cost (52 sessions)

 | Floor Cleaner No.61 (1:20) | 1:20 — 4L makes 80L RTU | $0.37/L | $1.87 | $97

 | Floor Cleaner No.61 (1:50) | 1:50 — 4L makes 200L RTU | $0.15/L | $0.75 | $39

 | Typical RTU floor cleaner | Ready-to-use | $2–5/L | $10–25 | $520–1,300

For a single 1,000 sq ft concrete floor, switching from RTU product to No.61 concentrate saves **$423–$1,203 per year**. Multiply across a multi-floor facility or multi-site operation for total procurement impact.

## Frequently Asked Questions

## Can I use any floor cleaner on concrete?

Not safely. Highly acidic cleaners will etch unsealed concrete and degrade sealers. Highly alkaline cleaners used repeatedly can break down epoxy coatings. Cationic surfactants leave sticky residue on porous concrete that attracts soil. Use pH-appropriate concentrates — mildly alkaline (pH 8–10) for general maintenance, neutral for polished or epoxy-coated surfaces.

## Do I need to rinse after cleaning concrete floors?

Yes, always. Concentrate residue on concrete surfaces acts as a soil magnet — it attracts and retains particulate faster than clean concrete. Rinse with a clean-water mop pass or autoscrubber recovery. Failure to rinse is the most common cause of floors that look dirty shortly after cleaning.

## What dilution do I use in an autoscrubber for concrete?

Standard autoscrubber tanks for commercial concrete: 1:30 to 1:50 for maintenance cleaning. Some machines have pre-dilution systems; check your equipment specifications. Using too-concentrated solution in an autoscrubber tank wastes product and increases residue risk. When in doubt, dilute more rather than less for autoscrubber applications.

## How do I remove tire marks from concrete?

Tire marks (rubber transfer) require an alkaline concentrate and mechanical scrubbing. Pre-apply concentrate at 1:5 to 1:10 directly on the marks, allow 3–5 minute dwell time, then scrub with a stiff brush or autoscrubber with a pad. Rinse thoroughly. Severe rubber transfer on unsealed dock concrete may require multiple applications.

## Is JANITORI™ Floor Cleaner No.61 safe for sealed concrete?

Yes, at recommended dilution. No.61 is pH-balanced for use on sealed concrete without sealer degradation when used at 1:10 or higher dilution ratios. Avoid using at full concentrate strength directly on sealed surfaces for routine cleaning — this is unnecessary and increases residue risk.
