Citric acid residue |

All acid type fluids will to that to metal. That's why I never use it on a saw blade. Even Evapo-Rust will leave a white scum on the metal, but it can be easily removed for the most part, but a saw blade will still be discolored with a matte finish that is not easy to remove.
The only way I can think of to remove that stuff is with a fine wire brush, by hand.
Were you trying to sharpen the files or just remove some rust?

Well, I just came a cross a popular mechanics article with someone asking the exact question. The answer was that it is normal for delta light-industrial machines. They use a transformer to create 24v to use for the magnetic switch.
Now my question is can I get rid of that and just wire up a newer mag switch? I don't really like the idea of a transformer sitting there powered up all the time and it would be nice not to have to plug and unplug it every time I use it.
