    Cleaning copper connections for high precision instruments

    Ok, thanks for the tip.

    Cleaning copper connections for high precision instruments

    and no, the final rinse with water did not change things. It actually looks better if I only rinse it with water without the soda.

    Cleaning copper connections for high precision instruments

    I have tried the baking soda after the acid. I'm not sure it does what it supposes to do. When I clean with the vinegar/salt solution I can see on the white tissue I use the blue residual of the oxidation: the copper looks perfectly clean. Then when I apply the water/baking soda solution to...

    Cleaning copper connections for high precision instruments

    Someone else has just suggested something that might do the trick: instead of alcohol, use an alkaline solution (eg water with baking soda) to both neutralize the acid (acetic or citric) and finalize the cleaning. I would then simply dry the piece with a hair drying. What do you think?

    Cleaning copper connections for high precision instruments

    Got it, thanks again. Question: if we leave the acetate layer there, would it be more corrosive than oxidation in the long run?

    thanks. Why is copper acetate more problematic than oxidation?

    Cleaning copper connections for high precision instruments

    Thank you, that's helpful. I've tried lemon instead of vinegar, but it creates a similar if not the same problem. Washing in water is not an option, unfortunately. The cleaning needs to be done in place, on rather small connections. I generally do everything with qtips, which obviously is a very...

    Again... why is it formed if the vinegar solution is not rinsed off?

    Cleaning copper connections for high precision instruments

    Hi there, I'm sorry, but that was not what I asked. I guess my main question is why the copper piece needs to be rinsed after the vinegar solution is applied? Why the solution produces the fast oxidation if it's not rinsed off after it cleaned the copper piece?

    Cleaning copper connections for high precision instruments

    Hi all, Here's my first post with a question I've been trying to solve for a while. I work with electronic components of very high quality and we try to make all our connections using thin copper ribbons of various thickness. I have started cleaning my copper connections with a solution of...
