How to use this guide
Use this page to align procurement, EHS, and operations on selection criteria, acceptance checks, and monitoring signals. Start by categorizing the dominant soil, then confirm flooring type and cleaning method. Finally, lock the constraints: low-foam needs, rinse limitations, discharge rules, and any site restrictions on odor/VOC.
Typical goals (define your KPI)
- Safety: reduce slip risk while maintaining required traction.
- Uptime: fast dry times to reopen traffic lanes and forklift zones.
- Quality: remove marks and film without dulling resin floors or leaving haze.
- Cost-in-use: performance at practical dilution and minimal rework.
Site map: soil + floor + method
Before choosing chemistry, map the job. The same detergent can succeed in one zone and fail in another. A quick map also improves RFQ quality and speeds up vendor selection.
- Soils: oils/hydraulic fluid, grease, rubber/tire marks, powders (cement, flour, pigments), metal fines.
- Flooring: sealed concrete, epoxy, PU, tile/grout, anti-slip textures, coated ramps.
- Cleaning method: dry pickup + damp mop, auto-scrubber, single-disc scrubber, pressure wash, spot treatment.
- Constraints: low foam, no-rinse requirement, restricted wet cleaning, odor/VOC restrictions, wastewater rules.
Fast selection logic (90-second workflow)
- Powders first: prioritize dry pickup + low-residue cleaning; avoid turning dust into paste.
- Oils next: choose alkaline degreaser strength by soil load; confirm compatibility with epoxy/PU.
- Rubber marks: add spot-treatment or controlled solvency; test to avoid whitening/softening.
- Lock low foam: verify foam performance at your dilution, temperature, agitation, and recovery system.
- Finalize EHS/discharge: confirm PPE, storage, oil separation, pH limits, and documentation.
Chemistry families & when to use them
1) Neutral / near-neutral cleaners (maintenance cleaning)
- Best for: light soils, daily/shift cleaning, resin floors where coating protection is critical.
- Commercial benefit: low risk of damage and fewer complaints; simple training for operators.
- Watch-outs: overdosing can leave film; choose low-residue, low-foam profiles for scrubbers.
2) Alkaline degreasers (heavy oils + industrial grime)
- Best for: hydraulic fluid leaks, greasy loading bays, machining areas, forklift lanes.
- Performance lever: alkalinity + surfactant blend + builders/chelants improves emulsification and soil release.
- Watch-outs: too aggressive chemistry can dull or whiten some coatings; manage dwell time and rinse strategy.
3) Solvent-boosted / microemulsion cleaners (rubber marks + heavy oil)
- Best for: tire marks, stubborn black marks, heavily trafficked industrial zones.
- Commercial benefit: reduces manual scrubbing labor; fewer repeat passes.
- Watch-outs: odor/VOC constraints, coating sensitivity, and foam behavior—especially in auto-scrubbers.
4) Acidic cleaners (mineral haze, efflorescence, grout scale)
- Best for: inorganic deposits, white haze, tile/grout mineral buildup (use controlled method).
- Watch-outs: strict compatibility checks; avoid on sensitive coatings unless confirmed; always control rinse and containment.
5) Add-on tools (not always “more chemical”)
- Defoamers: confirm detergent is defoamer-compatible; chronic foam is often a formulation mismatch.
- Brush/pad selection: mechanical action is a major variable; correct brush can reduce chemical aggressiveness needed.
- Water quality control: hard water drives haze/film; consider chelant/builders or a controlled rinse plan.
Selection matrix: soil × flooring type
Use this matrix to shortlist a chemistry family and define tests. Final selection should be validated with a small-area trial and a scrubber run.
| Dominant soil | Sealed concrete | Epoxy / PU | Tile / grout | Key risk to control |
|---|---|---|---|---|
| Powders / dust | neutral low-residue + strong dry pickup | neutral low-foam, low-film | neutral or mild alkaline; rinse if needed | paste formation / haze / film |
| Light oils | mild alkaline degreaser (low foam) | mild alkaline; confirm coating-safe | mild alkaline + brush; rinse where possible | slip risk from residual oils |
| Heavy grease / hydraulic fluid | strong alkaline degreaser; controlled dwell | heavy-duty but coating-safe; test small area | strong alkaline + agitation; rinse plan | coating dulling / discharge pH |
| Rubber / tire marks | solvent-boosted spot or higher dwell | spot-test solvent boost; avoid whitening | spot treat + brush; rinse to avoid residue | softening/whitening of coatings |
| Mineral haze / grout scale | acid cleaner only if confirmed; controlled method | usually avoid acids unless approved; test | acid cleaner + rinse/neutralize | corrosion/etching + containment |
Dilution, dwell time, and machine settings
Most failures come from incorrect dilution, too short dwell time, or wrong brush/pad. Standardize settings with a simple SOP: dilution, passes, dwell, and rinse plan.
Practical dilution & dwell guidance (starting points)
- Neutral maintenance cleaner: typically low concentration in scrubbers; focus on low-foam and low-residue performance.
- Mild alkaline degreaser: mid-range dilution with short dwell; increase mechanical action before increasing aggressiveness.
- Heavy-duty degreaser: higher concentration for spot zones; control dwell time to protect coatings and manage wastewater pH.
- Rubber marks: often needs spot-treatment + brush action; verify compatibility on epoxy/PU before wider use.
Auto-scrubber performance requirements (technical)
- Low foam at agitation: validate at your brush type, water temperature, and tank recirculation behavior.
- Recovery & dry time: detergent should not overwhelm vacuum/squeegee recovery and should avoid tacky film that delays drying.
- Filterability: some soils (powders/metal fines) can load filters; consider dry pickup first and monitor filter maintenance interval.
- Defoamer compatibility: if your site uses an in-tank defoamer, ensure the detergent does not “break” it.
Hard water note (prevents haze and film)
Hard water can cause white haze and “draggy” film. If you see haze: reduce dose, improve recovery/drying, use a controlled rinse, or select a formulation designed for hard water (builder/chelant system).
Specification & acceptance checks (COA/SDS + performance)
Procurement-ready specs reduce receiving holds and reduce reformulation risk. Separate checks into on-receipt and qualification performance.
On-receipt checks (incoming QC)
- Identity: product name, grade, manufacturer, batch/lot traceability, manufacturing date.
- COA typical items: appearance, density, pH (as supplied), alkalinity (if applicable), active content/assay (if applicable).
- Documentation: current SDS revision, COA per batch, and any required statements (e.g., low-foam, coating-safe, VOC/odor limits).
- Packaging: pails/drums/IBC, closures, labeling, hazard labels where applicable.
- Logistics: shelf life, storage conditions, lead time, Incoterms, delivery paperwork.
Qualification checks (site trials)
| Test | Why it matters | Pass signal |
|---|---|---|
| Foam & recovery | prevents tank overflow and loss of suction | stable low foam across full shift |
| Residue / film | film drives slip risk and re-soiling | no tack, no visible film after dry |
| Rubber mark removal | reduces manual labor and repeat passes | marks lifted without coating change |
| Coating compatibility | protects epoxy/PU investment | no whitening, dulling, softening |
| Dry time / traffic reopening | safety and uptime | meets your lane reopen target |
Simple site verification tests
- Foam check (scrubber): run at normal dilution and typical soil load; confirm no overflow and stable suction to end of run.
- Residue check: after drying, wipe with a clean cloth—look for “drag” or sticky film; reduce dose or adjust rinse plan if present.
- Slip-risk check: use your internal slip verification method; validate especially on coated and ramp areas.
- Spot test rubber marks: treat a small area; confirm no whitening/softening on epoxy/PU and no halo staining.
- Hard-water haze check: test in worst-case water hardness zone; adjust formulation or rinse plan if haze appears.
Wastewater & discharge (oil separators, pH, foam)
Floor cleaners are often selected on cleaning power but fail at discharge: excess foam, high pH, emulsified oils that bypass separators, or odor/VOC constraints. Align cleaning chemistry with your wastewater handling approach.
- Oil separators: heavy emulsifiers can keep oils suspended and reduce separation efficiency. If separation is critical, specify “oil-separator-friendly” behavior (site trial recommended).
- pH limits: strong alkaline products may require dilution control and/or neutralization policy; define this in the SOP.
- Foam at drains: foaming can become a housekeeping and safety issue; low-foam requirement applies beyond scrubbers.
- Solvent/VOC: solvent-boosted products can improve mark removal but may trigger ventilation and odor constraints.
Troubleshooting: symptoms → likely causes → fixes
| Symptom | Likely causes | First fixes to try |
|---|---|---|
| Foam overflow / poor recovery | overdose; wrong detergent class; contaminated tank; defoamer mismatch | reduce dose; rinse tank; switch to true low-foam; verify defoamer compatibility |
| Slippery film after drying | surfactant residue; overdosing; no rinse; “shine” additives | lower concentration; add controlled rinse; select low-residue formulation |
| White haze / spotting | hard water minerals; alkaline residue; slow dry | reduce dose; improve recovery; hard-water tolerant chemistry; controlled rinse |
| Coating dulling / whitening | chemistry too aggressive; too long dwell; solvent attack | step down alkalinity/solvency; shorten dwell; spot-test; switch brush/pad |
| Powder turns to paste | wet cleaning before dry pickup; too much water; insufficient recovery | dry sweep/vac first; reduce solution; use multiple passes; optimize squeegee |
RFQ notes (procurement-ready)
To reduce back-and-forth and ensure consistent quality, RFQs should include both technical targets and commercial constraints. Copy/paste the checklist below into your inquiry.
Technical fields (must-have)
- Floor types: sealed concrete / epoxy / PU / tile-grout / anti-slip textures; note any sensitive zones (ramps, coatings, line markings).
- Soils: oils/hydraulic fluid, rubber marks, powders, metal fines; note “worst zone” conditions.
- Cleaning method: mop vs auto-scrubber; scrubber model, brush/pad type, typical water temperature, dwell time, pass count, drying expectations.
- Performance KPI: low foam, residue control, rubber mark removal, slip-risk reduction, coating-safe behavior.
- Constraints: no-rinse vs rinse allowed, odor/VOC limits, EHS restrictions, areas where wet cleaning is restricted.
Commercial fields (to price correctly)
- Volume: estimated monthly usage, peak demand, and whether you need safety stock or dual sourcing.
- Packaging: pails/drums/IBC; pallet preference if relevant.
- Delivery: destination country/city, Incoterms preference, receiving windows.
- Documentation: SDS + COA per batch, lot traceability, and any required compliance statements.

FAQ
Why do “low-foam” cleaners still foam in our scrubbers?
Foam is affected by dilution, agitation, temperature, tank contamination (oils/soap/coolant), and defoamer compatibility. Always validate low-foam performance in your actual machine at normal soil load—not just in a bucket test.
Can a single product handle powders + heavy oils + rubber marks?
Sometimes, but it often increases risk of residue, foam, or coating damage. Many plants succeed with a two-product strategy: a neutral low-foam maintenance cleaner + a separate heavy-duty degreaser/spot product for special zones.
What causes slippery film even when the floor “looks clean”?
Residual surfactant or emulsified soil can leave a thin film, especially if overdosed or if rinse is not possible. Lower dose first, improve recovery/drying, and specify low-residue chemistry for coated floors and ramps.
