Most likely you will just have to wait for it to dry on its own. It is best to wash a engine while it is running so the ignition components stay dry.

The boot/pancake seal that covers the spark plug cavity gets old and lifts off of the surface of the head. This allows dust and water to invade the cavity that the spark plug is recessed into. Moisture in the engine compartment will often find its way into the spark plug cavity and short the spark to ground (misfire). Sometimes moisture will cause the COP (coil on plug) to also malfunction. If you have even one plug misfiring, it is wise to clean all the cavities and replace the spark plug boots. You will need an assortment of 1/4" wobble extensions, universal, and 7mm socket to remover the COPs. It can be done without removing the FI rails. #7 spark plug will prove to be the most difficult. You will also need to disconnect adjacent injector and COP electrical connectors (easily done). Do not despair. Visually inspect each cavity using mirrors and contortionist moves. If you see moisture and/or dirt in the cavity, you should clean it out. Get a spray bottle with rubbing alcohol and fill the cavity about half way. Let it soak a few minutes and blow it out with compressed air. Always use eye protection when using compressed air. Inspect for cleanliness and repeat as necessary. A word of advice, do not hesitate to use the aftermarket COPs. They work well and are cost far less than the Motorcraft brand.
