How can I safely clean up a spill of motor oil on wood surfaces?

To safely clean up a spill of motor oil on wood surfaces, first sprinkle an absorbent material like cat litter or baking soda on the spill to soak up the oil. Let it sit for a few hours, then sweep or vacuum it up. Next, use a mixture of dish soap and warm water to scrub the remaining oil stain. Rinse with clean water and dry the area thoroughly. Avoid using harsh chemicals or abrasives that can damage the wood.
