How to remove burnt oil stains on SS exhaust extractor

[RENESIS VIII]

Looks like the oil stains all all gone. No problem now.

I was actually quite happy with the improvements gained by just changing this extractor. Made quite some difference.

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.

What are the differences between mild steel and white steel?

Yeah. Now I only need top clean those engine oil remains and dirt on the exposed radiator piping under the extractor. Those are from old leaks long ago.

Hope it doesn't go rust.

mild steel can rust. Any steel also can rust, depend on quality

If rusted, throw away and install back stock one.

If u always check your engine bay and clean it, i think it'll last. the part that is neglected the most is the undercarriage area. the exhaust piping there is very hard to reach to clean it. even if send to car detailing, they don't do the undercarriage. need to go lorry wash shop.

If rust will already have rust spot. Iron rust easily like brake disc. After wash or after rain already rust. so mild steel is better in this respect. If want, stainless steel won't rust.....lol

I think the 'white steel' they refer to is Aluminised Steel

On my old proton saga, these type of extractors lasted for a long time.

Aluminised mild steel right? got grades for it oso. Stainless steel cost more and prone to cracks.

Yup, my wira had a HotBit's header. Crack here and there. After patching, it cracks at another area. In the end, changed to a new aluminised header. Looks very much like RENESIS's pic
