This is true, but an egg-cup per pint is a very weak solution so it will take minutes rather than seconds to do.

However, I agree that if you're not sure of what you're doing or if you're sending it off for anodising straight after, paying someone else to not f*ck it up is a good idea! ;)

Hi Jasper,

Try using a polymer 'black wheel' for an electric drill or angle grinder, its effectively the green side of a kitchen scourer albeit in a disc, black and a bit more rigid. I my V8 building days some rather doubious individual anodised the alloy cylinder heads, so I used exactly this product to clean it off. I have one in the garage if you want a picture.

Hope this helps.

Best regards,

James

I remember a rather pricey set of Mag yokes cracking when a set of nicely anodised forks were bolted into them, this was because the original anodised finish on them had been skimmed off by turning them down in a lathe and then re-Anodising them, the slightly smaller diameter that was left over stressed the mag yokes as they tried to clamp around them.

To me either skimming the surface or disolving it is still damaging the alloy So goes against what was called for in the original post
