The rust is severe; even after 30 minutes of plating, no zinc is formed
Thread Content
The cold-drawn wire has been exposed to rain for over a month, so it is heavily rusted. It can be cleaned through pickling, but no zinc coating will form even after 30 minutes of plating; re-plating also doesn’t work. What should be done? Please, masters, help think of a solution
First, grind to remove rust, then acid-wash the rust spots, and replating
Oh, give it a try, but there’s so much of it – it will take a lot of manual work to polish it
““First grind to remove rust, then pickle the rust spots, and replating” – this method doesn’t work; the result is the same whether grinding is done or not
