Alloy Corrosion.
 
Due to bead blasting the barrels and head, i have noticed that they are now growing the usual fluff due to the temperature changes in the shed, now i seem to remember using ally wheel cleaner in the past (phosphoric acid) but just wondered if there was anything better these days to restore the look?

"Mothers" is extremely good at bringing up old and tarnished alloy.
It ain't cheap but I swear by it. Its not an abrasive polish like autosol, it seems more like a chemical treatment and you don't need to rub the alloy hard to get a good finish on it. We've all had the autosol black finger syndrome :D

You misunderstand fella, its the barrel and head castings, they are not polished, but a fine mat finish from the bead blasting that i want to clean up, i don't intend to polish them, i need something to remove the alloy corrosion fluff.
is the "Mothers" just a wash then?

Sorry I misunderstood the problem, no mothers is not suitable in that case because it is a polishing cream. I'm not sure how to deal with the problem you describe.

How about some Gunk sprayed on and worked in with a thin paint brush and then jet washed off? Just thinking outloud ;)

I've got loads of those caravan type disposable dehumidifiers all over the garage and under the bike trying to keep the condensation/damp down.
The polished engine cases get quite furry.
