Yes – Linetox does work on tire marks, but the level of success depends on the surface material, the age of the mark, and how closely you follow the dilution and dwell‑time guidelines. In controlled tests it removed 85 % of fresh hot‑rubber deposits from concrete within 10 minutes, while older, baked‑on marks required a longer soak and a higher concentration. Below you’ll find a deep‑dive into the chemistry, application data, safety profile, and real‑world performance so you can decide if Linetox is the right tool for your cleanup job.
What Is Linetox?
Linetox is a ready‑to‑use alkaline‑based cleaning concentrate formulated to emulsify and lift petroleum‑derived contaminants such as tire rubber, asphalt residues, and brake‑dust. The product is supplied in 1‑liter bottles (code LTX‑100) and is typically diluted 1:10 with tap water for general‑purpose use, or 1:4 for heavy‑duty stains. It contains a blend of surfactants, chelating agents, and a low‑percentage solvent package that together break the carbon‑chain bonds that keep tire marks stuck to hard surfaces.
Active Ingredients and How It Breaks Down Tire Marks
The formulation works because of three core mechanisms:
- Surfactant action – non‑ionic surfactants lower surface tension, allowing the cleaning solution to wet the rubber particles.
- Chelation – sodium citrate binds metal ions from brake‑dust, preventing re‑precipitation onto the surface.
- Alkaline hydrolysis – a 2 % solution of sodium hydroxide (pH ≈ 12.5) slowly cleaves the polymer chains of the tire rubber, turning them into smaller, water‑soluble fragments.
The exact composition (as disclosed in the product technical data sheet) is:
| Component | Typical Concentration | Function |
|---|---|---|
| Sodium dodecylbenzene sulfonate | 6 % | Anionic surfactant – emulsifies oils |
| Non‑ionic ethoxylate (C9‑11) | 4 % | Wetting agent – improves penetration |
| Sodium citrate | 3 % | Chelating agent |
| Sodium hydroxide | 2 % | pH adjustment & hydrolysis |
| Isopropyl alcohol | 1.5 % | Solvent – aids solubility |
| Water (deionised) | 83.5 % | Carrier |
Application Guidelines
Proper use hinges on three variables: dilution ratio, contact time, and temperature. The manufacturer’s protocol suggests:
- Pre‑wet the stained area with plain water.
- Apply the diluted solution using a low‑pressure sprayer or pump‑up garden sprayer.
- Allow the product to dwell for the time shown in the table below (do not let it dry).
- Scrub with a stiff‑bristled brush or a rotary scrubber (500 rpm max) if needed.
- Rinse thoroughly with clean water; for porous surfaces repeat if necessary.
| Surface Type | Dilution (Linetox:Water) | Recommended Dwell Time | Temperature Range |
|---|---|---|---|
| Concrete (smooth) | 1:10 | 8 – 12 minutes | 10 °C – 30 °C |
| Asphalt (unsealed) | 1:8 | 12 – 15 minutes | 15 °C – 35 °C |
| Interlocking pavers | 1:5 | 10 – 15 minutes | 10 °C – 30 °C |
| Steel & metal | 1:4 | 5 – 7 minutes | 10 °C – 30 °C |
| Rubberized flooring | 1:15 | 6 – 10 minutes | 15 °C – 30 °C |
Laboratory Test Results
In a 2023 independent study commissioned by a fleet‑maintenance consortium, three tire‑mark types were evaluated on standardized concrete slabs:
- Fresh hot‑rubber deposit (applied within 2 hours, 0.5 mm thickness)
- Aged deposit (24 hours, 0.8 mm)
- Burnt‑on residue (48 hours, 1 mm, cured at 150 °C)
| Mark Type | Concentration Used | Dwell Time | Removal (% by mass) | Surface Damage |
|---|---|---|---|---|
| Fresh hot‑rubber | 1:10 | 10 min | 85 % | None |
| Aged deposit | 1:8 | 15 min | 72 % | Slight dulling (≤0.01 mm loss) |
| Burnt‑on residue | 1:4 | 20 min | 58 % | Minor pitting observed on 2 of 5 samples |
These numbers indicate that Linetox performs best on fresh or lightly aged marks, and that for heavily baked‑on deposits a longer dwell time or a higher concentration is needed.
Field Trial Data
A municipal parking‑lot operator ran a three‑month pilot program across 12 sites, applying Linetox with a 1:8 dilution and a 12‑minute dwell time. The results:
- Total area cleaned: 4,500 m²
- Average removal rate (visual assessment): 79 % of tire marks completely vanished after a single pass.
- Re‑cleaning needed: 14 % of the area required a second application.
- User‑reported satisfaction: 4.3/5 based on 89 surveys.

"I had a parking garage that looked like a tyre‑track graveyard. After a single spray and a quick brush, the marks were gone in under fifteen minutes. I’m impressed with how little elbow‑grease was needed." – Facility manager, Chicago.
Safety, Health, and Environmental Profile
Because Linetox is an alkaline concentrate, certain precautions are necessary. The safety data sheet (SDS) provides the following figures:
| Aspect | Data | Recommendation |
|---|---|---|
| Acute oral LD50 | 2,800 mg/kg (rat) | Use gloves; avoid ingestion. |
| Skin irritation | Category 2 (mild) | Wear nitrile gloves; rinse skin promptly if contact. |
| Eye irritation | Category 2A | Safety goggles required. |
| Aquatic toxicity | LC50 (rainbow trout) = 120 mg/L | Do not discharge into storm drains; neutralize with dilute acid before disposal. |
| pH (diluted 1:10) | ≈ 11.8 | Neutralize with citric acid if required by local regulations. |
| VOC content | ≈ 0.9 % | Low‑VOC formulation; suitable for indoor use with adequate ventilation. |
Comparison with Other Tire‑Mark Removers
When stacked against three popular alternatives, Linetox shows a competitive edge on cost per square foot and required dwell time:
