Hello, to use aluminium foil can work quite well if the tarnish is just superficial and there are no fatty residues from former use. If there is actual corrosion, not just tarnish, it might work not that well. Plus, something which is generally overlooked: the method is detrimental to the environment as part of the aluminium is dissolved and gets into the drinking water. It is very difficult and costly to get it out of the drinking water again. And Aluminium in drinking water is considered a health risk. In Germany silversmiths use something else. But this is for pro's only: concentrated ammonia. It dissolves corrosion well, all that is left to be done is polish the pieces - if wanted - to remove the dull specks corrosion inevitably causes. Ammonia can be detrimental to a person, don't breathe it in, dont let it touch your skin or eyes. It is not detrimental to the environment, there are bacteria all around us who can detox it easily. Again - be really careful, don't use it if you are not 100 % sure what you are doing ! Regards, Bahner
