cleaning engine bay

ok.. i cleaning the engine bay.. not well i might add.. i dont want to get all the grease and junk off cause untill i get it fixed theres just gonna be more on there the next time... but i dot want to get the dirt off... i just gonna use a hose.. soft water pressure... what should i cover so not to get wet if anything.. and remember.. im not blasting the thing with a pressure washer

keep the distributor cap and I think the ignition coil covered.

if youve got an intake, cover the filter, but i am not sure how critical that is... i know it was annoying, but i did it anyway... :)

thats about all i can think of!
