Need to get stains off my dirty pipe

[drgoatboy]

Whilst my turbo is in bits I thought I would take the opportunity to get some of the associated piping clean.
The pipe below is the first I am trying to tackle but I can't get it clean! Those blacks stains just won't come off the alloy.
I've tried degreasers but they only get so far. Tried some heavy detergent, even tried soaking it in coke overnight but it's still grubby. The dirt just seems to be dunk into the metal. Can anyone advise a technique and it product that may help?

Cheers GB

Thanks!
OK dumb question. What sort of solvent?

[one eyed mick]

any general purpose cleaner ,jizer ,wd 40 ,thinners, degreaser what ever you can get

many thanks, have been using Bilt hamber surface HD and its lost its effectiveness at the point you see in the picture. But to be fair thats not nasty solvent based. Will try something a bit more aggresive later on. Thanks.

It will need dry glass bead blasting or vapour blasting to get that clean - if you mean clean.

So I attacked it with carb cleaner and a wire brush. It got a bit more off but still very stained. So I broke out the 400 grit wet and dry. It's now lovely and smooth and just as dirty

I give up. Life's too short

You could try Solvol Autosol and wire wool if you've still some enthusiasm left.

Thanks, Yes you are probably right, the wet and dry got the worst of it off but it would need a lot more work to get it looking really nice. Its far too much trouble to be worth it.
Shame it would have looked great to get it really clean, but sadly time is more precious than a clean engine bay right now.

Local garage might have a tool washing station - hot high pressure might shift it?

Blasting and media blasting places near you? - sand / wallnut husk / carbon dioxide?

I have had success in getting an oil cooler much cleaner by boiling it in petrol. This would not be recommended in a paper house / anywhere.
(Oil had leaked, completely blocking the fins, no wonder the car overheated)

Try scrubbing it with a Scotchpad and Pepsi!
Honestly, not a joke.
Pepsi contains acid. I did this on cast iron manifolds and it worked well.
Saw the tip on Delboys garage video on youtube. Tried it and pleased with the result.
I also did it on the unpolished sections of my stainless exhaust. Again a decent result.

I soaked in coke overnight then scrubbed. It did take a bit of the tarnish off the pipe but it didn't do a huge amount. Thanks for the tip though.

Optiglanz might do the trick
