As the title goes, I need some suggestion from all of you. How do I remove the burnt oil stain on my SS exhaust extractor? Mine isn't polished finish, it is matte kinda finish. I wouldn't mind some scratches on it, as long as the ugly stain are gone.

Please share some ideas :adore::adore:

P.S i have tried using autosol, it didn't made any difference lol.

I heard from my mechanic that wiping with petrol can remove any oil stain. He uses petrol to wash away oil stain.

As in this kinda stain? I don't think petrol are strong enough to remove this kinda stain. I just grab a picture off google to roughly give an idea of what kinda stain

Wrap it with thermal wrap.

You're welcome.

This kind of stain looks like it really has burned into the steel itself. Not sure is it possible to remove them.

err i wanna try cleaning it first, as of now i have no intention of wrapping it:biggrin:
From a zero to hundred (performance) perspective, wrapping it will reduce under hood temperatures and contain the heat in, which means faster exhaust flow out, which means less pumping losses from the engine.

But if you only care about show and not go, forget I said anything.

Ya lo that's the tricky bit sigh..

Try scotch bite. If cannot, then steel wool....:driver:
I did some research on the web, suggested that never ever use steel wool. no idea why also hahaha

ya lo like burnt into the ss piping d, headache la

i think his got burnt marks coz of mech didnt wipe clean the extractor on his last workshop visit. if not his extractor would have that nice patina (correct ah?)
I miss the gold/blue runners :frown:

The reason why i avoid wrapping is exactly what sweelt shown you above. I hope you respect different opinions and no i'm not the kind of guy that cares about "show and not go". peace.

Yours are matte finish mah! If polished finish I am sure the steel wool will scar it.
You can try light sandpaper on one part and see what happens. If ok, then carry on

Set aside show/pretty/ugly/weight, wrapping with thermal wrap can compromise SS ? :confused:
http://www.centuryperformance.com/exhaust-header-heat-wraps-do-not-use.html
I laughed so hard reading that link my ass caught fire.
Let me summarize it for you

1. Exhaust wrap is effective at keeping heat in, more so than ceramic coating wish it ever can. Cool, no sites ever disputed that fact.

2. The site you linked to, Century performance sells Sanderson headers.. which guess what? Offers ceramic coating on their headers for a premium of $200 and up. The guy selling snake oil will say snake oil is good and Indian oil is bad, and vice versa.

3. People who parrot saying headers will fail due to wrap.. never wrapped theirs before... people who did, well... https://forums.nasioc.com/forums/showthread.php?t=498224

wrapped my stainless steel header 7 years ago.. guess what? It's still in one solid piece. Car is daily driven everyday. Just recently wrapped my downpipe... better check it for cracks cause it's crap quality. But I have absolute confidence in the header.

4. Headers do fail even without exhaust wrap, that's call thermal fatigue, but you can also call it CRAP headers. They can be crap due to weak design, high vibrations (especially), being stressed beyond designed capacity/load.

Example: http://www.s2ki.com/forums/s2000-forced-induction-142/exhaust-manifold-crack-record-thread-959149/

5. Saying thermal wrap causes rust and thermal failure on stainless steel is like saying oxygen causes rust and we shouldn't breathe...



The reason why i avoid wrapping is exactly what sweelt shown you above. I hope you respect different opinions and no i'm not the kind of guy that cares about "show and not go". peace.
People who hang out here long enough knows I'm not here to be a popular guy, I generally don't give a shit what people say or do. But quoting half truths like the Bible is a no joy for me.

So if you BELIEVE that thermal wrap is the cause of cracked headers, I've thrown that claim out of the window cause they crack without wraps too. Sure you can still believe that, but you better stop breathing cause oxygen causes rust dude.

I respect science and truth. Not opinions cause those are like assholes, everybody's got one. I've shown that your "reason" is invalid. And that link is written with commercial interest in mind. Guess what? I'm not selling anything.

And to answer your original question, give Brasso a try. But if it's etched in with oil I think it's pretty challengeing to remove, which is why I suggested wrap in the first place - that way you won't look at the eye sore and get a cooler engine bay at the same time. Black wrap looks damn cool on headers.

diy elbow grease laa. but u need to remove the extractor. LOL. but since you're removing it, just dip it in acid can do. :rofl:
It's damn tedious job to remove it man, gotta remove the radiator fan,crossmember,engine mounting bracket. sighhh.

Wet sand is sandpaper and water loh!
Hahahha got it :proud:

This topic has been discussed on and on all over the web. The reason i didn't want to wrap it now is simple. On a car that is driven short distances to work and home like mine most of the time, I doubt the runners will be hot enough to evaporate the moisture trapped inside especially during rainy days it could be worse. As the topic suggested, I'm asking if there is anyway of removing the oil stain. Period. A simple reply like the last line would be much appreciated, after all we are here to exchange ideas. Peace :fisheye::fisheye:

Don't be a wuss. A little oil stain never hurt anyone. Just chrome the thing and bling it with gemstones for special 3D effects. :biggrin:

And generally those titanium stained look is done with heat right? If you lost the stain you need to go heat it up with a hot welding tool or a flame thrower. I recommend the flame thrower. Melt body parts is the new black too. Doooooooiiiiiiiittttt

it's gonna take at least 2 days to remove, sand, polish and then install back. :rofl:
Deswai when the car is in the workshop then probably i bring extractor home to molest lol

Find exhaust heat shield cover, cover up......lol:biggrin:
Not enough space d, it's about 1cm away from my aircond fan. Which i already grind off the metal housing a bit. If not cannot fit at all.

Aftermarket header no place to screw heatshield...lol
ya lol

i've tried Autosol on a stainless exhaust manifold but it was a pain as the results were barely substantial or worth the effort to work on the entire manifold. You might be better off sand blasting it and have it thermal coated maybe

https://www.youtube.com/watch?v=IM9WDK105Bk

just stumbled on this video, there may be hope for polishing paste after all. The video says their polish is different because it is made for stainless steel exhaust specifically and unlike the regular pastes, this product is not aluminium friendly so that might explain its effectiveness for polishing exhausts

Other than Autosol, you try Brasso. Last time Brasso comes in clear liquid form. Now they have the cream version like Autosol. Brasso is a lot stronger tho.

Now I think I need to clean up oil stain on my extractor as well. Tried scraping it off and end up scratching my extractor. But the stain did come off from scratching.

AL is aluminum woh! or for exhaust some mixture becomes alloy......:hmmmm:
Really aluminum? I think it should be because I asked a friend studying degree for chemistry. What is AL. He said should be aluminum. The guy who sold me the exhaust also said this kind of extractor won't rust.

Here are some pic of how it is when stained and after I tried scraping it off.

Actually I just installed this today. :biggrin:

Try Scotch Brite with some strong scrubbing paste, next is steel wool if scotch brite don't work. Of course final stuff to try is sand paper....:driver:
I'll go home and look for scotch brite. Wait until I go back to Ipoh first on friday. Thanks for the suggestion. :biggrin:

don scratch too deep using sharp object. steel wool is better.
Scratching the surface only. Or maybe, I'll just colour them back with chrome silver marker pen. I have those.

Like what uncle vr said, it might be AL mix but definitely not pure AL.

Hope the surface of the extractor won't change colour or turn into dull looking surface after sometime. Currently it is still shiny. More importantly, as long as it doesn't rust.
