When having my engine cleaned/power washed ,what should be covered up or protected?

Hi. I just washed my engine yesterday, for the first time. I didn't cover anything, and I haven't noticed any bad effects. The engine looks like new again
I used a power washer with hot water and soap, then the brush, and finally the jet again with clean water. Same procedure as washing the car exterior. Just don't keep the nozzle too close to anything that looks electrical, or to the soft hoses, but everything is quite well waterproof. Try not to have the engine run very hot before, especially if you don't use hot water.

I would still cover the electronics - Fuse boxes, Spark wires on the top where exposed, etc. with garbage bags - espically if using any chemicals at all.
I am going with the armor-all method - spray it on and high pressure it off - it looks clean and makes maintance that much easier.

I use alumimum foil and cover the mass air flow sensor (right next to air filter), the throttle position sensor (front middle of the motor) and the electronics next to the throttle body. I just use Simple Green, let it soak for a few minutes (cold engine) and rinse off. Take the aluminum foil out and start the engine to dry the motor.

Well I heard that the protectant works as a degresear and shines up the plastic and rubber. But since I started my timing belt today, I just grabbed the Simple Green and went to the power washer for $2.00 -
Don't forget to take off the top cover like I did -
