How to Clean an Aluminum Intake Manifold

[@claymillican25]

Very informative!!! Thank You 😊

[@MuscleCarSolutions]

Thanks bud!

[@gizzmo5952]

I use a product from O'Riley, it's called aluminum brite. It removes everything down to the base aluminum. Works great, and rinses off with water, which neutralizes it. It's made for aluminum parts.

[@smaksymiv4950]

Is phosphoric acid ?

[@davidanderson2393]

When I worked for an industrial gas company we tried many products for cleaning to remove hydrocarbons(oil and grease) from metals. Based on personal safety simple green heated up and applied with a scotch brite pad works pretty well. On aluminum with oil and grease removed, I will use diluted alumabrite with a scotch brite pad to bring out the shine in cast parts. Some alumabrite can be very caustic and grey aluminum (stain) so start out diluting it and test in small area.

[@flinch622]

Alumabrite is acidic. Hydrofluoric acid, most formulations. A caustic solution is what is needed to neutralize a spill. I'm thinking a 5% solution? Don't believe that neutralization number blindly - check it out, and it won't be on an SDS. Why not? Damn good question - probably because EPA is controlling format. If an organization policy says "call someone", that's a bad plan [almost no plan]. The first casualty in most true emergencies is communications: so and so is away from their desk, or worse... a casualty. Now what?

[@astrawally8448]

Challenge here is that over time aluminium becomes porous due to surface corrosion, and grease/oils become embedded and that it is almost impossible to remove. A good example in aluminium truck bodies and trailers which get subject to diesel fumes and particulates, most manufacturers will not paint over bare aluminium if it has been used out in for this very reason, as the paint will not adhere and short of an acid dip/etch (impossible due to size), there is nothing more than a clean and polish which can be done. Examples where people have spent $20-30K in labour and materials only to have it peel off in 6 months.

[@TheGforcead]

​@@astrawally8448I know folks who buff flat machined aluminium engine cases on motorcycles and mag rims until they reflect like chrome. I didn't know you could do that, but other than Mother's car wax I don't know what you would use to prevent oxidation? I was amazed but I wouldn't recommend it and it wouldn't work on this application anyway.

Vapor Blasting/honing works really well. I've had a couple vintage intakes done by a local guy and they look brand new. If you have a special intake you need refinished, check for someone in your area who does vapor blasting.

[@MuscleCarSolutions]

Not exactly a DIY solution, which was the sole purpose of this video. Easy things you can do in your own to get that out of the box look back on an intake.

[@SPSteve]

@@MuscleCarSolutions true and you outlined some good alternatives.

[@wrenchmanhotrods1247]

I have been using a glass bead for years to do my manifolds , it saves a lot of elbow grease and does a great job especially in the hard to reach places .

[@gordocarbo]

Agree,,using a finer glassbead gives nice results wihtout pitting. Quick and easy just make sure none is left inside..easy to miss

[@nextphase7481]

I am planning on doing my manifold as well so your review is very helpful. Thanks! My thinking is that you need clean off all the baked-on grease first and then get rid of some of the oxide that has developed on the original cast aluminum. The grease is easier to remove and there are a lot of options (brake/carb cleaners, solvents like acetone, soap & hot water etc.). Removing the oxidation requires more care because you are removing some of the aluminum surface. If you use liquids, like acids or bases, they are corrosive to the metal so make sure they are not too strong, and be very sure to clean the surface thoroughly with water when you're done. You wouldn't want any of those casting pits to become holes! And leaving any bleach behind can turn the aluminum dark or even black. Safer to use abrasives (paper, metal brushes, or walnut shell blast). Thanks again for taking the time to share your work.

[@MuscleCarSolutions]

The products used were all suggested from viewers who had their “go to” method for cleaning intakes. Simple Green is my go to, and while I’m a little biased in it, the results showed why it’s the best. If something else comes along that’s better, I’ll be on that bandwagon next!

[@andrewhall836]

I'm restoring and modifying an old Kawasaki KZ750e and the aluminium has oxidised BADLY!! (Bike store outside for 12 years under a porch!) This has helped immensely!! Thanks! L&R From Down Under. Andrew

[@hybridmusclegarage4590]

Great video!! I always glass bead mine for that out of the box new look. No time for scrubbing lol!!

[@MuscleCarSolutions]

The only thing I didn’t like about the glass beading was it was more shiny when it was done. I like that dull, as cast look when they are new. But I TOTALLY agree. Scrubbing gets old!

[@zackk695]

Great video! I couldn’t quit watching it. Something relaxing and satisfying about taking a piece and making it look great. I wanted to see you use water because I think the brush is really what did the cleaning.

[@MuscleCarSolutions]

Thanks! Water won’t lift the oil and dirt. That intake was lightly pressure washed when I brought it home. Didn’t really remove any of that deep down nastiness.

[@briang4470]

My favorite thing for cleaning aluminum intakes is to use brake clean/carb clean to get the thick grime and varnish off first, then use either ATF or diesel fuel and soak the intake down with that and then use a nice brass scrub brush, it's time consuming but gives pretty good results.

[@MuscleCarSolutions]

Now that’s a new one. I might give that a try on this intake.

[@briang4470]

@@MuscleCarSolutions I prefer the ATF or diesel fuel method because after your done, there's a nice protective film on the intake so it won't tarnish or corrode while on the shelf, and when you use that method it's best to soak it and scrub it down several times, everytime you scrub it you will see the trash getting lifted out of the aluminum pores, it's is extremely time consuming but the intake will look almost brand new when your done. I did that recently to my Martin turbo intake for an sbc and the intake was super grimey but it was too nice to sandblast plus I wanted the aluminum to have a kind of shiney finish where sandblasting gives a flat dull finish.

[@MuscleCarSolutions]

I’ll have to give it a try. Sounds like a lot of work!

[@Eric-wq4lj]

Again, very informative. My manifold is yellow from years of gas leaking on it and I have tried most of these cleaners to no avail. I did mention this issue to the business that I use for powder coating and they said they would glass bead blast it and powder coat it in clear. They have done a lot that way. Never new clear powder coat existed. They said it was hard as a rock and would never yellow. Just another option. Thanks for the lesson on using the different cleaners!

[@MuscleCarSolutions]

Edelbrock has worked with powder coating for the last decade or so. Their Endurashine finish is powder coating. The video I did with the dual quad was on a powder coated intake. They’re flawless and extremely resilient to oils, fuels and even finger prints. They applied a clear over the top of it and they’ve lasted quite a long time. Now with a new powder coated finish (Black Plasma and Chrome Plasma), it’s on to some new variations. I think what it boils down to is the prep and what they are coating with. All that said, coating can be a very durable, beautiful finish. Doesn’t yellow. But for the home DIYer, I’m not sure it’s possible.

[@Eric-wq4lj]

@@MuscleCarSolutions Yes your correct, not for the DIY unless you want to invest the money and plan on doing restoration of parts on your own. Places like Eastwood sell the equipment if your willing to spend the money. Biggest expense is a oven. If you can find a used kitchen oven that will achieve 400 F. Then that will help out in the big expense of at all. I will see what it will cost to have my intake done as apposed to buying new and have it clear coated. My particular intake cost $480 new. Obviously the price of getting the old one clear coated as opposed to buying a new will make the decision. Again, just a suggestion if you can't seem to clean your intake.

[@stevemiller7654]

Clear powder coat is not "new"....

[@johnfry9010]

Best stuff I ever used for this is a Cleanser type product called ZUD , it is still around and it works great , I was using this stuff back in the 70's . I forgot to mention I also used a brush with it to scrub the manifold and rinse it with water . Glass bead blast in my opinion is the absolute best but for a cleanup in between the ZUD does the trick .

[@astrawally8448]

I've successfully used sodium bicarbonate as a blasting medium on cast alloys to bring up that 'as cast' shine. Due to its fine particles, it does a better job in the detail. Being water soluble, it can be easily removed with little chance of leaving behind the blasting medium, which is an issue with walnut, silica, etc.

[@Amack1964]

Vapor blasting returns them to the out of the box look have done a few now and love the finish

[@torque395]

I use lacquer thinner and a "chip" brush (those cheapie throw away wood handled brushes that cost 50 cents or so) and then cut the bristles down to about half of their normal length. That gets it pretty good, another option is lacquer thinner and an air powered engine cleaning gun - gasoline works in both cases in place of the lacquer thinner and is just as good or better, but the smell will really get to you, even worse than the lacquer thinner. Both are best done outside, and definitely without any smoking, open flames, welding, grinding etc anywhere nearby. Another thing I like to do is take parts to a car wash, or get out my hot water pressure washer (but be prepared to get soaking wet!) and then with any of these options, you will still have to use a rag and some clean solvent to go over the whole thing to get it entirely clean. A brush alone won't get it all perfectly, nor will pressure. You can "abrasive blast" it with something like glass beads without having to do any wiping with a rag, but like you said it will change the surface appearance. And while you may not need to wipe it with a rag, you do still need to brush or spray away the bulk of the grime first and make sure there's no moisture or "wet" grease on the surface because the blaster will just spread that around and make a bigger mess, as well as contaminate the abrasive media which will prevent you from recycling and reusing it. And don't bother with the walnut shell media or anything similar because in my experience, it's just a waste of time and money. As you can see, there's no "one solution" for aluminum - it really takes a combination of things to get it done right. It's not like steel or iron where you can throw it in the hot-tank and let the caustic chemicals clean it up for you since those chemicals would damage the aluminum....

[@nv1493]

By far the easiest way I've found is to use the old harbor freight hand sandblast gun with pretty much any sort of media. Literally like brand new and its not hard to thoroughly clean out the intake tubes. Even the small crevices can't escape...

[@MuscleCarSolutions]

I have a harbor freight system. It’s getting replaced next shop I occupy and have the room! Extremely useful tool!

Gasoline is a solvent. cheapest and effective. Hence the phrase, "Gas is for cleaning, Alcohol is for drinking and Nitro is for racing."

Pour it in a spray bottle. Works great.

Super Purple/Purple Power works great cleaning grimy engine bays. Just spray it on, let it sit then, hit it with a brush and finally a pressure washer. Might work equally well on intakes. 👍

[@silverstreak232]

One thing to remember about acetone is that it evaporates into acetylene gas. So, proper ventilation would be a good idea. Acetylene gas is heavier than air and will lay low to the ground which can create a hazard. It won't dissipate into the air easily. Also, I used a lot of Simple Greene to clean dies and production tooling. It worked very well, and in some cases it was all we were permitted to use because it safest to use. It's hard to get a brand new as cast finish because the surface of the aluminum develops a thin layer of oxidation that will dull the appearance. Very good video! I enjoyed it and learned something new!

[@MuscleCarSolutions]

Simple Green will always be the go to cleaner in this situation.

[@ivermec-tin666]

I have heard very good things about Simple Green Extreme for cleaning and degreasing aluminum. It was specifically engineered for use on aircraft, and will not etch or eat aluminum. My experience indicates that kerosene is just as effective as any canned aerosol cleaner, and less caustic, although it is flammable.

[@MuscleCarSolutions]

Used kerosene a lot when I was younger, but it’s not a detergent so it leaves behind a lot of what it just took off. Other than that, it does clean well!

[@Monkeybizness707]

As a former aircraft mechanic in the marine corps (KC-130s) I can tell you that we were forbidden from using simple green on our aircraft because it is corrosive to aluminum if not completely cleaned off. Having said that, if you completely clean it I'm sure it is fine.

[@ivermec-tin666]

@@Monkeybizness707 Simple Green Extreme is very different than their main product line. Extreme is specifically formulated for use on AL. The regular Simple Green product will etch AL with a vengeance.

[@Spiritof_76]

The acids etch the metal, and when properly neutralized are a good base for primer and paint. If you want to leave the as-cast semi-gloss of aluminum or polish it, I'd skip the acid and use a cleaner.

Best things iver ever used with cleaning alloy parts, back when I used to for work caterpillar (westrac) was the CAT brand "PENETRATING OIL" Literally spray it on, leave it a few minutes the a quick scrub. But the cheaper way I found was using "5 stars - Degreaser" I'm quite certain the crushed walnut shell is for car panels etc because the friction from using sand heats what ever your sand blasting where the walnut shell grit is meant to have sharper edges and doesn't cause as much friction so less heat.

Just use degreaser and a pressure washer, then use some aluminum wheel cleaner for open pore aluminum. Don't let it stay on there long, maybe 30-45 seconds. Then hose it off with a garden hose. Maybe Don't even put on the nozzle and the water pressure not up very high. You don't want that cleaner getting on you as it is an acid. Kinda mild acid but still, SAFETY FIRST. Gloves long sleeve shirt, long pants, safety glasses. All this hurts a lot less than having the cleaner hurt you. Anyway you will love the results. It works great. I've used it on an aluminum water pump that was looking dingy too. Just tape up around the openings and the seal area and don't forget the weep hole. Made it look new.

The reason why you really don’t want to use a metal brush on aluminum is the metal brush leaves traces of metal particles behind that will rust overtime. Same thing as if you’re cleaning stainless.

Stainless wire brush is fine (just like if prepping aluminum for TIG) But, yeah steel wool or brush is not a great idea.

[@whereisamerica7384]

Blasting works best with soda on aluminum. I know this will sound nuts, but WD40 followed by Napa or Tractor Supply Aluminum Brightner(aluminum trailer cleaner) and a pressure washer seems to work best. Other than hot tanking that is.

[@lawrencejneuser8801]

Judging from your results, i think if you took one of the good cleaners and run it through the parts washer that you had specifically for cleaning aluminum car parts you would have a quick and reliable outcome. The acetone cleaned as good as the starting fluid I used, you just didn't have the pressure behind the fluid. Most people just have one parts washer but it would be good to have something especially set up for special purpose cleaning. I would use a good ventilation hood for some of these projects.

[@jims2286]

Well sir, what works for me is a fresh bag of silica sand for blasting. I use new because after awhile it becomes powdered and cleaning takes longer.

That’s interesting. WD40 would have been the last thing I would have used. Maybe I’ll give that a try sometime and see how it soaks into the aluminum.

@@MuscleCarSolutions I hope it helps. Been using it for many years on all cast aluminum, Intakes, pump housings, alternator frames etc…it minimizes oxidation. I run a (alum.)6-pack intake and spray a light coat on once every size months…no more ox. 👍

[@MuscleCarSolutions]

I’ve seen the old guys use kerosene on it and it looks rather awful. I guess if it keeps the crud away, it’s probably worth it.

[@stevehamilton9418]

@@MuscleCarSolutions kerosene, wow…I guess if it works. Yeah, I imagine it looks awful!

I kinda like the Simple Green test you done . Just for the fact that it is a milder,less poisonous solution. No matter what cleaner is used, I myself have had the best luck or results most of the time using a stainless steel wire brush ,. But of course you would would only want to use it for cast finished parts,. I definitely wouldn't recommend it for a polished finished surface, unless of course the finish doesn't matter and. The main objective is just to clean the parts. The stainless steel brush scrubs the the contaminates out, as opposed to a regular steel brush seems to scrub them in. If that makes any sense.

Your welcome,. As about the subject of clear coating an aluminum intake manifold. I never seem to have very much luck with it it lasting very long for me. Instead if I have parts that I want to keep looking aluminum color,. I like to just paint them with the aluminum color Rust-Oleum Bar B que grill paint. I prefer the original satin one,. The Rust-Oleum "ULTRA" grill paint doesn't look as good in my opinion.

[@mustangmadness2619]

I have used a sand blaster works very good, just turn the air pressure down for aluminum = 75 - 80 lbs. Tape up any surfaces that you dont want blssted.

[@mustangmadness2619]

I have also used good automotive clear not rattle can clear with good results.

How I like to clean my intakes is to use a 1/2 cup of borax (washing powder) mixed with warm water then I add dawn diswashing liquid (blue). The muriatic acid works great on steel and iron but not great for aluminum. I also use a parts washing brush and a smaller brush. ButI let it soak for awhile. Not a fan of acetone because it is carcinogenic

[@bobbytheitguy4289]

When you do comparison tests, you should always have a control (like clean water} just demonstrate that its the product removing the stain and not just the liquidity of the substance you are using.

we use simple green to clean tanks in the Army

[@SOLDOZER]

Vapor blasting. Will look good as new but probably cost you almost as much as new.

[@plumSRT]

CLR and a toothbrush does wonders, also.

[@ByGraceThroughFaith777]

Gunk engine degreaser and superclean work too

[@michaelgarrow3239]

I just stick them into my Acme time portal. Gets it clean and removes scratches too.🤓

[@stevodakine1]

SOS Pads and warm/hot water. Cheap and easy, I use it on rims and the polished swing arm of my KX250.

[@MuscleCarSolutions]

On polished parts I can see that as an option, but a porous intake probably won’t get in to break up the oil/grease/dirt/fuel deposits.

[@willkincaid5841]

I was gonna say some hot water and some dawn, dip the whole thing in a bucket if you can and let it soak. I'd say you almost have to use a pressure washer after giving it a good scrub down then wash it off. Probably wouldn't get heavy stains off though I wouldn't think. I've only done smaller parts like that and entire engine bays.

[@laurensiemens1436]

With acetone you really need to use in a well vented area.

[@garage3119]

Vapourblasting works a treat on ally manifolds.

[@MuscleCarSolutions]

Not sure that’s a tool that DIY folks have laying around the garage. But I’m sure they’d clean well.

Always pour acids into the water, never pour water into acids. The acids can actually flash boil the water as you are adding water to acid. FYI

[@TheWanderingGeezer]

It would have been nice to include a couple dedicated aluminum cleaners as well.

[@MuscleCarSolutions]

@@TheWanderingGeezer I’d have to go back and watch this video again but I’m 100% sure I said why I tested the products included in this video.

[@deadcarnahans1932]

I ALWAYS paint my manifolds. Paint protects what's under it. Unfortunately I now have a second hand intake that was not painted. I'm just going to wire brush the heck out of it so it will accept Hunter Green.

[@____MC____]

I just tried aluminum brightner. Worked pretty good. Still requires a rag on some spots

[@MuscleCarSolutions]

Seems to be the general misunderstanding with this video. Wasn’t looking to polish or brighten the intake. Just clean and return back to the as cast finish.

[@____MC____]

@@MuscleCarSolutions i had some dirt lines on a manifold that didnt fit in the ultrasonic cleaner all the way and it took it right off. It does make it brighter, but the point i was making is that it does clean. Its just a spray on and spray off deal too. Just had two little spots that required scrubbing. You can probably use that suff right on the engine safely for regular maintnance too.

[@gearhead7896]

Have you used Bleche-Wite before on Al intakes? Try it next time works probably better than all of them except the acetone.

[@MuscleCarSolutions]

It quite literally says do not use on aluminum. 😂 No I haven’t used it or will I ever.

[@gearhead7896]

@@MuscleCarSolutions It works really good. Yes it says that. I use it in small amounts and completely rinse it on my intakes.

@@evlutionzllc5519 there’s a reason why it specifically says NOT to use on aluminum.

Hey, if you really want to make the problem go away - send it to me! I could really use one for my autocrosser build lol. But seriously now the best I have seen is hydroblasting and the penultimate is dry ice blasting (who can afford one of those rigs in their home workshop though apart from Rebuild Rescue)

Wonder how that castrol purple would do?

[@MuscleCarSolutions]

I’m guessing it would probably do well as long as the purple dye didn’t stain.
