ChanMin said:another note ah guys... Brasso and AUTOSOL are only POLISHING COMPOUNDS.
they give you back the shine and remove the muck.
they wont stop the tarnish from coming back.
in fact might leave the metal surface unprotected and tarnish may occur quickly
basically adequate care must be taken AFTER polishing to ensure that the surface is protected from moisture.
what i do is polish then protect with WD40 or some other equivalent water displacement product ...
