Hey!
I read a few posts about pickling and how people were afraid that the solder would come apart, dissolve or something...
Would anyone be able to tell me what kind of time they mean by "too long in the pickle". Is it two days, or a week? I don't hesitate to leave my work in the pickle for 2 days. Should I not?
Also, I read that after soldering the piece should go in the pickle without waiting or the oxide could "settle" in the metal. But I sometimes file and sand my piece first and then leave it for the night in the pickle. Is it a mistake?

Thank you so much!
