Detail engine bay with WD-40 (91 Civic Si)

[Robb]

Here's a writeup on how to clean up a dirty engine bay using WD-40.
This engine bay had a 20 year buildup of rustproofing and dirt, that dried up onto the paint.

I used WD-40 and a paintbrush and 4 microfiber towels.
Works amazing on 20 year old buildup of dirt and rustproofing. No joke.
Car had been sitting for 10+ years.. I basically spent 4 afternoons/evenings total on it.

STEP BY STEP

1. Go to the automotive store, buy 2 cans of WD-40 , 4 microfiber towels, paintbrush.
2. Open Hood.
3. remove battery, air filter box and arm, fuse box cover, wiper motor, map sensors assembly, coolant overflow tank, move away side wires and tubes on shock towers.
4. Start attacking the dirtiest parts with WD-40.
5. Spray and brush/agitate the grime/dirt
6. Wipe off dirt with towel.
7. Once all the bay is clean, you can buff and polish the paint around the bay and dress the rubber hoses with rubber and vynil dressing.

Keep doing this until all dirt is removed. It takes a while, but well worth it.
WD-40 wont remove the paint.

Note: As you will notice, some parts were replaced/restored as well.

I found an easier way to do this : go to the car wash, use some 'white spirit' or gasoline to clean the engine bay, and wash after application ^^

[Robb]

WD40 leaves a greasy film onto parts, after using it, use degreaser and rince, otherwise dirt is gonna stick to it quickly.

You can clean it with water after.
