I've noticed a slight build-up of the white powdery coat that often affects aluminium in this weather, on the FMIC.
What is the favoured method/product for removing this and then protecting the alloy from further build-up? I remember using a specific acid based liquid in the past and even alloy wheel cleaner but wondered what other people have tried.
I wondered if a spray of WD40 or similar after treatment would help protect the alloy, considering you don't want to put anything on that might insulate the IC.

Dan-

What I did with my top mount was sand back the corrosion and then polish it up afterwards and protected it with wax and its fine so far over 5 months or so

You mean pipework have oxidation?

If yes you can powdercoat the pipework,actual core you can't powder coat,but nice coat of black will looks good

i would imagaine that the powder blocks up the cooler the sand blasting probably doesnt help with things

No, it's the core. It's not corrosion just the powdery oxide that forms.

Unfortunately aluminium oxide is harder than the aluminium itself, so it can be a ******* to remove and will always come back unless you can coat it with something to protect it from the air / elements.

As said, you can probably spray something on to make it look a bit fresher, but the best bet is to paint it from new if you are ok with accepting some slight cooling loss.
