How to remove burnt oil stains on SS exhaust extractor

[RENESIS VIII]

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.

Maybe I need to continue scraping them off with something?

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....

don scratch too deep using sharp object. steel wool is better.

I'll go home and look for scotch brite. Wait until I go back to Ipoh first on friday. Thanks for the suggestion.

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.

remove extractor, sand it down with wet sandpaper, spray few layers of 750 degrees heat resistant paint.

This is a lot of work. The installation yesterday took quite some time.

If not heat resistant will turn color the moment it gets hot.....lol

Better not try it if that is the case. Who knows what colour it will turn to. But I used them to colour my engine oil cap from black to silver then later another layer of red ink on top. Colour haven't turned.

Engine oil cap still can touch even engine is hottt...hehehe

I don't want to touch anything.

After driving for short distance yesterday, I tried to wipe off the oil stain using wet cloth after the engine is turned off for like 5 minutes. Still can touch, but with wet cloth.

Just came back after some long distance driving. Open up the hood to check out the oil stain. Suddenly they all disappeared and now only my stupid scratch marks is left.

The exhaust shop guy was right. He said the the stains will disappear.

He told me that is some kind of anti rust oil. At first I was skeptical because the coloured turned so black. Even yesterday during dinner, I took the car for a short drive. The mark is still there. But after some long drive like 30 minutes each time back and forth, the oil stain mark is gone. still got some left near the head of the extractor. Might burn off eventually?

Then just leave them first and see how it goes......

The next long distance trip I will do will be back to Ipoh on Thursday or Friday. Lets see if it burns away those oil or not. I'll take a picture after that.
