Exup's Boike Spruce-up! (Red made me post this)

[Fazerider]

Quite alot  of the bolts have rusted and I was thinking of running a charge thru some soda water to de rust them.....anyone done this???? What does the sacrificial metal need to be made out of??

Any bit of scrap iron will do, though avoid stainless as that's got chromium in which can make very toxic compounds.
