Degreaser

I got a car for my gf for free, but the valve cover gasket leaks and with that its all over the engine bay over time and neglect.

Whats a good engine degreasing product that I can pretty much spray into the entire engine bay area and clean it up before I replace the valve cover and do some other maintenance to it?

I use Simple Green and I use some brushes to agitate the dirty places. First I mist the engine bay and then a spray Simple Green everywhere. Becareful of the Alternator and the PCM/ECU. Make sure you cover them with a plastic bag.

there was a good one on here not to long ago someone did a nice write up, im wanting to say it was Black Magic or Mothers or some big brand. Just warm the motor up and spray it down on everything and rinse off.

In the shop all we ever did was use brake clean (non chlorinated) on everything

simple green here also, works great.. I also use my leafblower to get most of the water off afterwards :thumbsup:

This is pretty heavy soiled and built up from the last I remembered... I'll give it a shot though. :D

do you guys usually dilute the simple green or just use it straight from concentrate?

If there is a lot of oily build up, you might have to go with a legit engine degreaser. I generally use the Gunk brand (non foaming version) for the really bad jobs. Simply green, the purple stuff (can't remember the name right now) or APC+ from meguiar's will work well on lighter stuff and is a little more environmentally friendly. ;)

Simple Green actually has a pro series line that is an automotive degreaser. i've been using it for years on my engine bay. i usually spray it on a rag then wipe it on the engine.

I always keep a spray bottle with undiluted Simple Green concentrate just for this purpose. If you mist the engine as stated above, it will be diluted, but I spray, let it sit for about 15 minutes, and then do a light spray rinse with the hose. Yes, the Gunk brand degreaser also works well.

apc+ for lighter stuff and super degreaser for heavy stuff. both my meguiars

Parts cleaning is essential to many industrial processes, as a prelude to surface finishing or to protect sensitive components. Electroplating is particularly sensitive to part cleanliness, since molecular layers of oil can prevent adhesion of the coating. Solvent degreasing is a process used to prepare a part for further operations such as electroplating or painting. Typically it uses petroleum, chlorine, or alcohol based solvents to dissolve the machining fluids and other contaminants that might be on the part.
