I wouldn't bother about pulling that #5 plug.

Starting a car up to just move it in or out of your garage can cause the engine management computer to get confused.
It's more likely that plug got wet with gas, not oil, which is why it can clear itself quite quickly.

Even if you are in the habit of doing that driveway shuffle, this can happen randomly.
Dealerships are familiar with it from having to start cars up to just move them a few feet.
Happens even to the reliable Japanese brands.
Some makes and models are completely immune to it, but I have heard that BMW is somewhat susceptible.

(I don't think the wash itself has anything to do with it - just the very short run cycle.)

See how it goes over the next while, especially if you are able to avoid those short run cycles.
