I have some soft point heads that are pretty tarnished... I realise it's a bit fairy-ish to ask but if I want to get them nice and shiny again is a sonic cleaner or tumbler viable? I'm thinking it may just damage the heads (though I realise many think that doesn't matter)?
p.s. Before the usual tirade of slagging off ensue's is there any chance someone could just post something useful and helpful?... some poor sod asked about dog-friendly ice-cream recipe's the other day and you'd think he'd asked advice on mugging granny's or something
