Wanna clean your engine bay without screwing anything up? Here’s how I do it:
1. Let it cool down
Don’t spray water on a hot motor — you’ll crack something or steam-sizzle your coils.
2. Cover the sensitive stuff
Bag up:
-
The alternator
-
Battery terminals
-
ECU or fuse box (if they’re exposed)
You don’t need to go crazy with tape — just cover what’s vulnerable to water.
3. Dry brush or blow out the loose stuff
Use a paintbrush, leaf blower, or air gun to get rid of dust, leaves, sand, etc. Gets rid of the crap that just makes mud when it gets wet.
4. Spray a degreaser
Use something engine-safe like Simple Green, Purple Power, or Gunk Engine Degreaser.
-
Spray it on plastic, hoses, valve cover, and greasy spots
-
Let it sit 5–10 mins
-
Keep it off painted body panels if it’s strong stuff
5. Rinse LIGHTLY
Use a low-pressure hose, not a pressure washer. You’re not trying to blast the motor — just rinse off the degreaser. Don’t soak coil packs, sensors, or connectors.
6. Dry it off
Blow it out with air or a leaf blower, then wipe with microfiber. Then, start the engine and let it run for 10–15 minutes with the hood open — that'll help dry up anything that’s left.
— and that's pretty much it. Hope it helps!
