Here's what I did!
Not sure about this but am guessing that the water that ends up down the sink is fairly neutral being a mix of acid and alkaline. I still think its better than using shop bought silver cleaners
Frugal-ness: 5/5 Didn't cost a cent! managed to use things that I already had in the cupboard!Time cost: About 15 minutes per piece. It was the first time I had done it and so the first piece took longer than the last!
Skill level: If you can boil water for a cup of tea - you can do this!
Fun -ness: Marvellous fun! Almost magic to watch!
