Thank you everyone for your help. I think you are onto something here. When I bought the paper I purchased large sheets and chopped it up by hand with no gloves on.
I'll buy some more (in a pad) and wear gloves while handling it. Then if that doesn't work I'll try a drop of tween.
Gold toner - yes, I have some waiting to be used and I'll cut down on the sodium thiosulphate in the fixing bath.
But I'll start with the paper. I want to be sure of the results before I start messing with the rest.
