removing tarnish

evening all,

i am cleaning up an old razor, and its coming up pretty well, but i am struggling to remove all the tarnish from the pattern on the handle. a lot of it has come off using the baking soda method but i have done this twice now and there is still tarnish on there. are there any other ways of removing tarnish other than this method?

thanks

yes its a 1912 'old type'

have given it a 3rd baking soda bath and its starting to look pretty good - give it one more tomorrow i think then polish it up with Silvo
