Super polishing cream
This brass polishing cream by Søe-Jensen, and is some of the best and toughest on the marked. You only have to use a small dose of the polishing cream to make your brass handles shine - can also be used on other brass items.
The secret of this polishing cream is that it won't dry out the material, but will leave it with a protecting surface, that will keep the brass shiny for a longer period of time,
