I just do not want to harm anything under the hood.
The car wash power washer wouldn't have anywhere near the pressure of a home power washer [which can do damage if not careful].
I cleaned the engine compartment for over a decade using the coin op washers... I usually leave the engine running to keep it hot as I'm doing it. Although I suppose it is possible to damage the exhaust manifold, I typically just avoid getting too close to it.
Don't aim the spray at the intake, or the back end of the electrical connectors, but I regularly washed the engine control computer box with no ill effects.
Should you hear your engine stutter while washing, get the spray out of there in a hurry. Never happened to me, but if you are that nervous, ask your dealer's mechanics.
