  • Sticky blue shine on my yellow passivation

    Hi there, I’m new here and also just starting to do some more zinc plating, and blue/yellow passivation. Mostly for classic car parts. My setup is home made, I build myself a tank with pump, power supply and so on. But I think I still have some issues with it. When my parts come out of the electroplating bath they look really clean and shiny, but from the moment the go true passivation they become a bit sticky en have a blue shine on them. And they don’t dry up as nice as I want them to. If some one have any ideas for me then they are very welcome! There are some pictures to make my point. Thank you in advance. And sorry for my English I’m from Holland.
