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

D_Train · 05-16-2007, 11:57 PM

Whats the best way to clean out the engine? Just a rag and some scrubbing strength? are there products that can clean the grease off of everything no problem?

Also, i'm not talking about just the engine bay, but also the other components in the engine.

Brake cleaner works better than PB. It also dries alot faster than PB. PB actually leaves a residue that will burn off if the part that you sprayed with it gets hot.

Most grease will just disappear if you hit it with brake cleaner.

PB is used as a penetrant and rust inhibitor, its not known for its cleaning ability, although it does work but smells like ass and doesn't evaporate in seconds like brake cleaner.

I think the ass smell helps it work better, and it doesn't wash out of clothes.

What can i get the brake cleaner on as far as engine parts? Like, if I just go wild and spray it on everything and start wiping will i hurt anything? obviously i'll use some discrection (sp?) but you know...

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.

with the brake cleaner (tetrachlorethene) it will take a layer of paint or more so make sure you have degreaser and some water to wash it off, so u don't take more paint off than u want. other than that make sure ur clean and careful not to get it on the outerpaint or it could cause paint and clearcoat damage
