My cars radiator fan is on?

I was washing my cars engine bay and out of nowhere the fan came in and the keys weren't in the ignition, I covered up everything I was supposed to and the fan is still on after 10 minutes? I turned on the car and it started up fine, should I be worried? It's a 88 Honda Accord by the way

You got the fan switch wet. It shorted and ran the fan. Nothing to worry about.

Let it run for a long time to help evaporate all the water off the engine.

Hmm! Sounds automatic.

Did you spray water on the fan relay and cause it to short out?

You got the electrical connections or the relays wet fooling around trying to make your motor pretty!
