Is it safe to wash engine room?

I kept it clean over the 22+ years I have had it by washing the engine compartment at least once a month or so at the car wash.

Spray on degreaser and soap, rinse off with high pressure water. No problems with wires getting wet, no problems with water getting in the engine. You just have to be certain the water spray does not get injested.

It's as easy as that. You can use "cleaner" or "degreaser" or just "soapy water"... want to go crazy use brushes of different sizes, from broad wheel brushes to toothbrushes- then use a moderate hose flow or very careful a light jet spray from distance- you do not want to force water past electrical seals and gaskets.

I read a lot of people freaked out about "washing the engine"... look, it is an EXTERIOR area of the car, designed for water-proof performance. Probably IP65 or something along those lines. IT IS DESIGNED TO GET WET!

$65 for the dealer to do it? Crazy.
