Quite a few parts inc the gearbox, plenum etc have developed white oxidisation. One way is to use a soft brush, but any chemicals that would do the job and leave a clean surface?

Wouldn't mind doing this myself while I'm stripping my subframes

Nothing available to the general public, no.

Even chemmy etch would leave an uneven finish because the corrosion will act as a barrier.

The best way is mechanical removal. Personally I'd use an alu oxide blast.

Spoke to these guys they seem to think it will remove oxidisation.

That'll do it. Phosphoric or hydrochloric acid is what we use to chemmy etch at work.

I don't know for sure but I would assume that it's a diluted version of what we use, so might need some serious soak time to etch anything. Try it on a small patch first if you go down this route.

I'd still want to blast it personally.

It is more so for the gearbox not keen on blasting the casing with all the gears still in place, just want to clean it ie apply and wash off.

This is interesting. I have a nismo intercooler, and i would like to clean it back to try and make it look a bit tidier. However i have idea what to use, and further more dont want to damage the fins. Any ideas?

alu clean from frost works like a charm,

just watch out for the fumes but its gets it back to brand new

It is ok to use on the gearbox and wont eat up the seals and gaskets?

well i wouldnt spray it directly onto your seals as you'll only be cleaning the exterior casing, shouldnt be that difficult to avoid

 

[ForgingEngineer]

mechanical polish, chem etch and anodise once you've built a special processing plant that is. how long does the finish need to last?

Vapour blasting.

 

[FRRACER]

That does look good, but not easy to find a place local to me that does it!!

I got my bits vapour clean in oxford.

 

[stephenwap]

What does it involve? It's hardly like a steam clean is it?

your girls panties before you wash them after she done with her period .trust me best thing for bringing alu up to its shine .my girl knows that every month she has to take them off and use them on my engine & make it shine .they have to be redder than red for the sparkle .
