Kerosene is moderately effective at removing oil stains, particularly for non-polar or hydrocarbon-based oils like motor oil or grease. Its effectiveness depends on the oil type, stain age, and surface material. For fresh stains, kerosene can break down oil through solubility, but older or set-in stains may require additional methods. However, kerosene is not universally effective; it struggles with water-soluble oils or stains on delicate fabrics. Safety and practicality are also concerns, as kerosene is flammable and may leave residues requiring rinsing.

The effectiveness of kerosene stems from its chemical composition as a non-polar hydrocarbon solvent, which dissolves non-polar substances like oil. A 2018 study in the Journal of Environmental Science and Technology found that kerosene removed 65-75% of motor oil stains from cotton fabrics within 10 minutes, compared to 50-60% with water alone. However, its performance dropped to 40-50% on synthetic materials like polyester due to fiber compatibility. For cooking oils, which contain polar compounds, kerosene’s efficacy diminishes significantly, as shown in a 2020 American Chemical Society report, where it achieved only 30% stain reduction. Kerosene’s volatility also limits its use, as rapid evaporation can trap residues. The Environmental Protection Agency (EPA) notes that kerosene’s environmental persistence and flammability make it unsuitable for large-scale stain removal, with alternatives like isopropyl alcohol or commercial degreasers often preferred. In summary, while kerosene works for specific oil types and surfaces, its limitations in safety, residue, and versatility render it a situational option rather than a universal solution.
