  1. 1

    Pour fresh kitty litter directly onto the oil. Use enough to completely cover the oil. Cover the kitty litter with sheet plastic or a small tarp and allow it to absorb the oil for three days.

  2. 2

    Sweep up the used kitty litter with a broom and toss it in a garbage can. The oil soaked kitty litter you sweep up will weigh a lot more than the dry kitty litter you poured three days ago, so don't try to toss it all out at once. Sweep it into small piles instead of one big one and toss out each pile separately.

  3. 3

    Apply a small amount of liquid washing powder onto any remaining oil stain. Use enough to create a sudsy lather on the stain.

  4. 4

    Apply some water to the detergent and scrub the stain vigorously with a hard wired scrubbing brush.

  5. 5

    Rinse away the detergent with water. If the stain remains, reapply the detergent and water, then scrub again until the stain disappears completely.

Tips and warnings

  • If removing the stain proves extremely difficult, then apply a thick slurry of powdered washing powder to the surface and allow it to soak in overnight. Wash away the detergent the next day.
  • Be cautious as to where you dispose of the oil soaked kitty litter. The oil is flammable, and if exposed to heat, may spontaneously combust.
