Cleaning up copper sulfate residue


 

We use copper sulfate in a simple continuity tester. Since copper sulfate is conductive we use it to test continuity of 20-36 ga. magnet wire without having to burn the insulation off. Is copper sulfate corrosive to paint or metals? When copper sulfate if left to dry, it leaves a corrosive looking residue. Do you recommend any type of cleaning agent to completely remove this buildup?

Thanks,

Just not a good idea to leave salts around any metal. A copper sulfate solution will corrode many metal surfaces, since it has some water of hydration, and will probably absorb more from the atmosphere. It is slightly acid.
