Hang your salamis outside to dry. Chose a place where they're under some cover, in clear circulating air and protected from animals and birds. If you have an outdoor shed or garage it might do or you can rig up a simple hanging safe like this from wire mesh and a small dustbin lid. A dry white mould is acceptable on the outside of the skin but patches of fur or coloured mould should be washed off as they develop with a weak solution of vinegar in water
