**Wash them gently with dish soap and warm water, dry thoroughly, and switch to food-grade mineral oil for future care.** One application of olive oil is not a reason to discard the utensils.

Olive oil *can* become rancid; that does not mean the oil you just applied already is. The reason to avoid it as a wood treatment is that it can eventually become sticky and develop unpleasant smells and tastes. [University of Maine Extension](https://extension.umaine.edu/publications/3108e/) recommends food-safe mineral oil instead.

Here’s what I would do:

1. **Wipe off any excess oil** with a clean cloth or paper towel.
2. **Hand-wash briefly with warm water and ordinary dishwashing detergent**, using a soft sponge or cloth. Rinse well. If the surface still feels greasy, repeat a gentle wash.
3. **Towel-dry immediately, then let the utensils air-dry completely**, with air circulating around them.
4. Once dry and free of objectionable odor, **apply a light coat of food-grade mineral oil** intended for cutting boards or utensils, following its instructions and wiping off excess.

Your concern about wood damage is reasonable, but **brief washing is normal care for wooden utensils**. Prolonged soaking, dishwashers, and leaving the wood wet are the bigger problems; aggressive scrubbing is unnecessary. The University of Minnesota’s [guidance specifically for wooden kitchenware](https://conservancy.umn.edu/bitstreams/677316b1-52c2-4a71-9049-1ffd740f3f3d/download) recommends washing in warm sudsy water without soaking.

There is a limitation: **washing removes surface oil, but cannot guarantee extraction of all oil absorbed deeper in the wood.** My practical recommendation is to clean it normally rather than attempt complete stripping. Mineral oil will not neutralize any olive oil that remains. If an unpleasant rancid odor persists or returns after washing and drying, stop using the affected utensils for food.

As for the alternatives:

- **Mineral spirits:** I would skip them. They dissolve oil, but ordinary hardware-store products are sold as paint solvents and equipment cleaners, without instructions establishing this use on food utensils. [Manufacturer’s intended uses](https://kleanstrip.com/solvents-and-thinners/odorless-mineral-spirits/).
- **Vinegar, lemon, salt, or baking soda:** They offer no clear advantage for extracting absorbed oil. Dish detergent is the appropriate grease cleaner, and avoids unnecessary abrasion.

If washing raises a little fuzzy grain, let the wood dry and lightly smooth it with fine sandpaper before oiling.
