Looking for advice on what chemicals to use to clean my engine bay. It is very dirty with dirt, grime, oil build up, etc. not looking to use a pressure washer but rather do it by hand. I have no issue with that. Just need to find some good chemicals to do it. I'm also looking to paint the top of my intake manifold and a few other pieces as I no longer have my engine cover on due to the spacers. I know they say tire cleaner for the rubber hoses. Also has anyone painted their intake manifold or any other parts under the hood? Just looking for ideas.

Kudos for avoiding the pressure sprayer and doing it by hand.

I would start with ordinary car wash, or maybe some dish/kitchen soap. After that, there are products such as Super Clean and Purple Power Degreaser, both I've purchased at Walmart. These are both concentrated detergents so it's best to wear some latex or nitrile gloves. I've used them to clean many of the pieces from underhood, altho I usually remove the pieces to clean them.

Also, go on a scavenging hunt for small brushes. You can't have too many different shapes and sizes. Toothbrushes and Q-tips are a good start, but there are many others that can be very handy. Some towns have specialty shops that carry a variety of cleaning tools - the Container Store comes to mind. Baby stores have bottle brushes which are helpful, too.

Lastly, a pair of very long needle nose pliers are great for clutching a wad of paper towel for cleaning and for swabbing up excess liquid. An air hose can be a great tool as well, but it can also blow liquid onto stuff you don't want to get wet.

After these detergents, you will start getting into acids and/or caustic cleaners (such as CLR) which can be harmful to many surfaces, so I recommend avoiding them.

Thank you! I have read/heard many good things about Purple Power degreaser and almost bought some at Walmart. I always wear gloves when working with this stuff as I get them free from work. I do have a few small brushes, also need to find a few more. Have a bunch of stained and new microfiber towels, about 20 to be exact. I will start with this and post back. Any downsides for using the tire cleaner/protectant on the rubber hoses? I have some new mothers interior cleaner that worked great on rubber too. Now to do some painting. Also going to add some red LED's under there too. Will post results. Might not paint the intake manifold due to heat, they say the paint will effect the way the heat escapes the manifold. I'll find some things to do.

The intake manifolds are aluminum aren't they? Are they shiny from factory or no? Just looking into cleaners. Both the suggested above are not save for aluminum. So I need to find out what is all aluminum on my engine. Before I go ahead with this. Like in this picture. Is the part that the oil fill neck goes into aluminum and I would what it should look like haha. I'm sure not this dark.

I doubt the tire cleaner would hurt hoses, but I can't be absolutely sure.

One other thought, when using the degreaser, start with it diluted a little bit - that is, try to avoid using it full strength. HTH.

I know that I asked this before, but don't remember the answer... Is that spacer made of wood?? Certainly looks like wood! Just seems strange to use wood for something like that...

I used Super Clean on the oil pan on my 3.5L G6 (LZ4) recently with no issues. That said, I supposed it could mar a polished aluminum finish. But that shouldn't be a concern with the rough texture on the intake and valve covers.

Thanks for that @1impalavision1! I just bought some GUNK and plan on using it tomorrow. Like I said, just nervous with the thought of hosing things down in the engine bay. I will be doing it all by hand. What is your process for doing it? If you use a hose, what should be covered?

Cover air filter, alternator and avoid spraying near the coil packs and spark plug area.

With the GUNK, spray on and let it sit for a couple of minutes. If rougher engines with alot of oil residue build up, i would recommend getting a brush and rubbing in the product.

Just so you know i sprayed on hoses and aluminum pieces.

Thank you man! I might just spray lightly with a hose. Do you cover the battery at all? I will need to cover my ECM/TCM as well seeing how I have the Overkill ASI now. Is it ok if the battery gets wet? Do you clean yours with a hose? I'm going to cover the alt, battery, TCM/ECM, air filter and might do the coil packs behind the engine just to be safe.

Yeah cover all what you listed. I used a pressure washer at my local DIY car washes.

If it doesnt clean spray it on again. But a brush would help and a hose should get the job done.

The use of technology for business processes automation and the new benefits they offer to business is one of the key factors of business success in today's world. Companies that rely on traditional business management styles are not wrong, but these traditional approaches are often not effective enough to cover the huge business environment around the company. Those who want to succeed should consider a way out of this dilemma by changing the business management approach through cleaning company scheduling software.
