**I’d start with a gentle hand wash, then switch to food-grade mineral oil once the utensils are completely dry.** A single application of olive oil is usually a manageable care mistake.

1. **Wipe off excess oil** with a clean cloth or paper towel.
2. **Wash briefly with warm water and ordinary dishwashing liquid**, using a soft sponge or cloth. Rinse thoroughly. Hand washing this way is standard wooden-utensil care; avoid soaking, boiling, and the dishwasher. [Wooden utensil maker’s care guidance](https://www.carvedwoodenspoons.com/faq)
3. **Towel-dry immediately, then let them air-dry completely**, with air reaching all sides.
4. **If they smell normal and feel clean**, apply a light coat of mineral oil specifically labeled food-grade and suitable for cutting boards or utensils. Let it absorb, then wipe off the excess. [John Boos care guidance](https://www.johnboos.com/frequently-asked-questions)

Your concern about the pores is valid: **washing removes surface oil and some accessible oil; it cannot guarantee removal of everything absorbed into the wood.** My recommendation is a practical first step, not a complete extraction procedure. Mineral oil also won’t neutralize any remaining olive oil or prevent it from oxidizing.

On the options you listed:

- **Soap and warm water:** The best starting point. Detergent helps carry grease away, so vigorous scrubbing is unnecessary. Brief washing followed by prompt drying limits the risk of swelling and cracking.
- **Mineral spirits:** I would avoid them for this job. They are paint-thinning solvents with ingestion and inhalation hazards, and I cannot give you a reliable household procedure for verifying their removal from porous utensils. [MedlinePlus](https://www.medlineplus.gov/ency/article/002798.htm)
- **Vinegar, lemon, salt, or baking soda:** These are sometimes recommended for stains or odors, but they offer no established advantage for extracting absorbed olive oil. Salt and baking-soda scrubbing add abrasion. [John Boos’s stain and odor advice](https://www.johnboos.com/frequently-asked-questions)

If an unpleasant rancid odor persists after washing and thorough drying, **hold off on oiling and using them for food**. Ask the maker about resurfacing them; sanding may remove affected surface wood, but deeper oil can remain. For a recent light application with no off odor, gentle cleaning and normal care are a reasonable approach.
