A curious one... We purchased some ‘archive quality’ brass paperclips a couple of years back, and to our concern have discovered that some of them are dulling/developing a coating… It’s in an area of our cellar which we know has some humidity issues, and at least at the moment none of the residue is coming off onto the paper - but even so it seems like Not Good News.
We have not got very far in conversation with the supplier so far. So I was just wondering if anyone else has come across this phenomenon, and if so if you have any tips for dealing with it?
Thanks folks, Lynette

The Working Class Movement Library is a charitable trust, and is recognised at home and abroad as one of Britain's most important collections of working class history. We believe that in these turbulent times such history has never been more relevant, and we want as many people as possible to know about and use the Library. We need to find £80,000 each year to keep the Library going - find out more at www.wcml.org.uk/appeal.
