TARNISHED ALLOY

(1/2) > >>

Swivel:
Anyone know how to remove tarnish from Alloy without highly polishing it? I don't want a highly polished finish as the chainring wasn't like that originally, but it does have some little black tarnish marks all over it which I want to remove. Any ideas? I will try good old soap and water 1st but I doubt that'll clear em up.

Any help appreciated.

graeme:
what finish did it have originaly?

Was it laquered or anodised?

MartyC:
If it's a ProNeck or TufNeck one they have a burnished type finish (SteveP uses a pummice stone/sharpening stone to get the same effect) and then they are silver or clear anodised.  I'd try a light rub over with something like Peek or Meguairs Metal Polish before using Autosol  :daumenhoch:

Swivel:
Its laquered I believe, its a Haro Uni Directional Chainring, its NOS, but tarnished. I think Autosol maybe too strong as it'll start to give it that shiny look and that's what I want to avoid.

graeme:
Whatever finish is on it, laquer you think, will need to come off. Any discolouration to the alloy will be under the finish.

It would then need re-finishing as stock (polished, diamond cut, brushed, whatever) then refinshing, in this case laquering.

Theres no other way really.
