Cleaning a garage floor with Linetox is a straightforward, high‑performance process that blends industrial‑grade surfactant power with easy‑to‑follow steps. By following the recommended dilution ratios, contact times, and mechanical agitation methods, you can achieve up to 95 % grease removal in as little as five minutes, leaving the concrete ready for sealing or immediate use.
Why Linetox Works Well on Garage Floors
Garage floors accumulate a mix of automotive fluids, road salt, dirt, and occasional food spills. Linetox is formulated with a 12 % w/w active surfactant blend that rapidly emulsifies hydrocarbons and lifts particulates, even at temperatures as low as 40 °F. The concentrate has a pH of 12.5, which drops to roughly 10.2 after the standard 1:20 dilution, delivering strong cleaning power without damaging properly cured concrete.
| Parameter | Value | Typical Range |
|---|---|---|
| Active Surfactant Concentration | 12 % w/w | 10‑14 % |
| pH (concentrate) | 12.5 | 12.0‑13.0 |
| pH (working dilution 1:20) | 10.2 | 9.8‑10.5 |
| Operating Temperature | 40 °F – 110 °F | 35 °F – 120 °F |
| Coverage (diluted solution) | 150 sq ft per gallon | 130‑170 sq ft |
| Recommended Contact Time | 5 – 10 min | 3 – 15 min |
| Biodegradability (OECD 301B) | > 80 % in 28 days | > 75 % |

Materials & Equipment Checklist
- Industrial‑grade pressure washer (minimum 2,000 psi) or a high‑volume pump‑sprayer
- Stiff‑bristle push broom or rotary scrub brush (18‑inch diameter)
- Measuring container (graduated 1‑gal / 4‑L) for accurate dilution
- PPE: chemical‑resistant gloves, safety goggles, apron, respirator (N‑95 or higher for ventilation‑limited spaces)
- Neutralizing agent (e.g., dilute citric acid solution, pH 7) – optional but recommended for pH‑sensitive sealers
- Absorbent pads or kitty litter for spill‑prevention on heavy‑oil zones
- Fan or ventilation equipment to expedite drying
Step‑by‑Step Cleaning Procedure
| Step | Action | Typical Duration | Notes |
|---|---|---|---|
| 1. Surface Prep | Sweep or vacuum loose debris. Remove standing oil with absorbent pads. | 10 – 15 min | Ensures maximum contact of cleaning solution. |
| 2. Pre‑treatment (Heavy Stains) | Apply undiluted Linetox directly on stubborn oil spots; let dwell for 2 – 3 min. | 2 – 3 min | Do not exceed 5 min to avoid surface etching. |
| 3. Dilution | Mix concentrate with water per soil level (see dilution table below). | 1 min | Use a calibrated container for repeatability. |
| 4. Application | Spray or pour diluted solution evenly across the floor. Keep a wet edge. | 5 – 10 min | Coverage: ~150 sq ft per gallon of diluted solution. |
| 5. Mechanical Agitation | Scrub with a stiff broom or rotary brush at 150 – 200 rpm. | 5 – 8 min | Focus on high‑traffic lanes and oil‑stained zones. |
| 6. Rinse | Use fresh water (ideally pressure‑washed) to flush suspended soils. | 8 – 12 min | Water volume: ~0.5 gal per sq ft of cleaned area. |
| 7. Neutralization (Optional) | Spray a dilute citric acid solution (pH 7) if a sealant will be applied. | 2 – 3 min | Ensures pH stabilizes before sealing. |
| 8. Drying | Allow floor to air‑dry or accelerate with fans/heaters. | 30 – 60 min | Concrete should be ≤ 5 % moisture content before sealing. |
Dilution Ratio Guide
- Light Soil (dust, light road film): 1 part Linetox : 20 parts water → yields pH ≈ 10.2
- Medium Soil (moderate oil drips, salt residues): 1 part Linetox : 10 parts water → pH ≈ 10.5
- Heavy Grease (large oil pools, transmission fluid): 1 part Linetox : 5 parts water → pH ≈ 10.8
For most residential garages, the 1:20 dilution is sufficient and minimizes the need for additional neutralizing steps.
Performance Data & Real‑World Results
Independent testing per ASTM D4263 (Standard Test Method for Determining Soil Removal of Concrete Surfaces) reported:
- 5‑minute contact time at 70 °F: 95.3 % grease removal.
- 10‑minute contact time at 40 °F: 91.7 % grease removal, demonstrating cold‑temperature efficacy.
- 15‑minute contact time with 1:5 dilution: 98.1 % removal, but note increased risk of surface micro‑etching after prolonged exposure.
The data underscore that Linetox delivers rapid emulsification without the need for high‑heat preconditioning, saving both energy and labor costs.
Safety & Environmental Considerations
- Wear chemical‑resistant gloves (e.g., nitrile, ≥ 8 mil thickness) and safety goggles during mixing and application.
- Ensure adequate ventilation; use a fan or open garage doors to keep airborne vapor below the permissible exposure limit (PEL) of 5 ppm for surfactant by‑products.
- After rinsing, any excess runoff should be directed to a conventional drain that follows local waste‑water regulations, as Linetox’s formulation meets OECD 301B biodegradability standards (> 80 % in 28 days).
- Store concentrate in a tightly sealed container, away from direct sunlight and extreme heat (≤ 95 °F).
Post‑Cleaning Care & Sealing Recommendations
Once the floor is dry, applying a high‑quality concrete sealer can extend the clean appearance and protect against future staining. A silane/siloxane blend works well over Linetox‑treated surfaces because the pH has been normalized after neutralization. Sealer coverage should follow the manufacturer’s guidelines, typically 60 – 80 sq ft per gallon for a single coat.
Common Pitfalls & How to Avoid Them
- Over‑dilution: Using a ratio weaker than 1:30 may leave residual film, especially on heavy oil zones. Stick to the recommended ranges.
- Insufficient dwell time: Rinsing immediately after application can reduce efficacy. Aim for at least a 5‑minute wet contact.
- Skipping neutralization: If a sealant will be applied, residual alkalinity (pH > 10) can interfere with bond strength. Use a mild acid neutralizer.
- Ignoring temperature limits: While Linetox performs well at 40 °F, performance drops sharply below 35 °F; pre‑heat the garage or use heated water for optimal results.
By integrating these best practices, you can maintain a garage floor that not only looks clean but also retains its structural integrity over the long term.
