Commence by cleaning off any kind of dirt which the surfaces of the silver articles had contracted whilst making, as that would entirely spoil the burnishing. For this purpose, take pumice powder, and with a brush, made very wet in strong soapsuds, rub the various parts of the work, even those parts which are to remain dull, which, nevertheless, receive thus a beautiful white appearance; wipe with an old linen cloth, and proceed to the burnishing.
