Cleaning under the hood

[Splashdance]

My under hood area is a little dusty and grimey. How can I SAFELY clean up everything?? (w/o using a weekend and a toothbrush)

a car wash works great just spray the whole under hood with simple green and get to washing.

Use simple green then hose it all off. I went mudding and under my hood was completely brown sprayed it down with simple green a lot and hosed it down and it cleaned it all up

I like to stay off of the relays and alternator.

After it dryies, spray some shiney stuff on it and then wipe it down with a towel.

Diesel fuel spray a bit on everything. leaves it shiny and cleans it very well

Inside the users manual they show the areas to cover to prevent water intrusion. Alternator, batteries, and LH fuse/relay box off the top of my head.

Spray with water first, then use a degreaser, let it sit for a few minutes, rinse. Repeat as necessary.

If it's really nasty go to the store and buy a can of cheap oven cleaner spray it let it sit for five min. then wash it off with low pressure water. This works great for the areas with lots of oil and dirt sticking to things.

Purple Power works great for me....I just use it with the garden hose and a spray nozzle. Clean as a whistle every time!

Make sure you don't do it while the motor is hot....rapid cooling/heating of metal could cause thermal embrittlement which could lead to cracking. If I clean under the hood, I do it first thing in the morning and then leave the hood up to dry.
