They look as though they have been in that tote a long time. If it were me, I would hang soak each individually in Orvus...it is a liquid soap used by farmers to wash the utters of their dairy cows...very gentle....if you live near a " country type store, check it out.....anyway....that would freshen them up. Then I would be comfortable handling these pieces.... A great find and enjoy bringing them back to life.
