![]() Here is the article on how the experiments came about: ![]() The product I want to try out is WD-40's specialist corrosion inhibitor, but I have not been able to get this in AU yet. I still use a lot of WD-40 for other applications, especially on steel. So these days I treat potentiometers, electrical connectors, IC socket etc with MX-3. Inox's MX-3 is very long lasting too as a lubricant. I still have the copper test plate, and the results remain the same over 1 year Now.Īlso, WD-40 is a short term lubricant after a few months it has "left the building" so to speak. The explanation from an Inox company representative being that it does not contain dieselene encomponents. The only product I have found that does not do this is Inox's MX-3. On testing a range of other products, including Deoxit, RP-7, Lanox, WD-Servisol, they are all exactly the same in this respect. ![]() This is not via chemical attack, but via a Hygroscopic effect (is the working theory) WD-40 is terrific a at preventing rust on bare steel, even in a hostile environment, however in common with a range of other products, actually enhances corrosion on copper & brass. Then, curiosity got the better of me and I tested a range of other products. I set up some experiments checking out the effectiveness of WD-40 as a corrosion inhibitor and a lubricant. As explained in the attached article, a fellow on a vintage computer forum strongly advised against WD-40 (the standard, not specialist product) be used on anything containing brass. One of the more difficult areas is the restoration (rather than replacement) of IC sockets in vintage computers, what to best clean and lubricate them with. On a number of forums, when this question comes up, I noticed that all of the remarks were anecdotal or relating to personal experience applying a product to a wide range of objects/components, and it was much like trying to compare apples to pears.
