Engine bay detail

(on the Corolla)

Two cleaning agents:

1. Bucket of water with Murphy Oil Soap. Remove thick grime with a rag and this mixture.
2. 303 Aerospace cleaner diluted 1:3 with water and put in a spray bottle. Spray the 303 and let sit on grime for a few minutes. With a spray bottle of water only, shoot away the 303 and the grime. Wiping with the rag dipped in water+MurphyOilSoap is good too for wiping up the 303.

After everything you can see/reach is clean, wipe down all clean plastic/hoses with a damp rag, then immediately spray a light mist of Meguiar's #40 Vinyl & Rubber cleaner/conditioner. This really revives the black plastic housings and hoses. Let sit for 5 minutes. Blot any big pools of Megs #40 (creamy color of liquid).

Drive around a mile or two to get the engine warm and evaporate the Megs #40.

Admire your clean engine bay!
