Removing motor oil: pick your surface
Motor Oil is an oil and grease stain, usually from overalls, tools or a part carried through from the garage. The chemistry stays the same wherever it lands — but the safe way to treat it changes completely with the surface, which is why each pairing below has its own guide.
Not water-soluble
Water alone will not touch this stain; it needs an absorbent, surfactant or solvent stage.
Not heat-sensitive
Temperature is not the enemy with this one; the removal method itself does the work.
Fresh vs dried-in
Motor oil is heavier and dirtier than cooking oil — it carries carbon and metal particles that dye the fibre grey as the oil spreads. Fresh spills need generous absorbent powder before anything wet. Aged motor oil oxidises into a dark varnish that home degreasing lightens but rarely removes completely.
