cleaning brass

how is it best to clean old discoloured brass?

soak overnight in tomato ketchup, scrub with a toothbrush then rinse thoroughly. Once it's clean and dry polish as usual and add a final layer of furniture polish to prevent it tarnishing again. It works really well

clean using a recognized cleaner specially made for brass like      martin carr & day which was only available to the ornamental metal trade when first produced  available at most hardware and diy shops
