What is a good way to clean out the engine bay?

I wouldnt spray it on the electronic parts, for pretty obvious reasons.

break clean works amazingly, i used about 7-8 cans on my engine swap and everything looks brand new, from the turbo, turbo manifold to valve covers. Do yourself a favor and buy a cheap brand, otherwise it gets pricey for parts cleaner. Its all basically isopropyl anyway.

There are different brake sprays out there, so check the chemical ingredients on the cans.

Years ago it was 111. trico, which was great, and could be used on everything without harm.

But now some have acetone, which you DON'T want to get all over and into electrical connectors. The puddling liquid will damage the plistic.

Johnsen's brake cleaner spray's main ingredient is acetone.

If there is a bunch of grimmy grease stuff, then use some spray engine degreaser (99cent store), or pure Simple Green. Let it sit on the area for about 30 min, then wash that off with brake spray.

DON'T do it in the driveway, as you will have a mess.

NEVER, NEVER, NEVER use carberator spray. Do you have a carberator on your car? NO!

It way to strong, and WILL damage plastic.

Also, be sure to protect your fenders, and paint.
