black patina on lead free

(saltspring island, bc)
i am having a hard time with the consistent take of black patina
nova brand...good and strong...i am trying to move all my work to lead free and am currently trying 97 tin /3 copper as well as 95 tin'4.5 copper and .5 silver.I have had little trouble using the solder as i have always gone with full heat on my iron
100w with 900 degreee tipwhen using the patina i find it will come off in places when washing, so i reapply and the finish is ok.
any tips would be cool as this is how i make my living
AnswerThis is a question that I can't answer as I have never used lead free solder. Hopefully someone reading this can give us some advice. If they can help, the answers will be in the comment section just below here.
