| Rust on my rounds.... |

| Sid_Vicious:
I left some old and rusty wrenches beyond saving in white vinegar and one in citric acid for weeks as an experiment once, and the vinegar ate more metal than the citric acid did. So my suggestion would be a short time and some fine steel wool to get rid of the rust... It is my hope that during the winter I will have time to begin experimenting with elektrolysis as it is my understanding it only removes rust and nothing else. And I liked the idea of the soaked towel to use on the mill or lathe. |

I'm no expert but as a layman I would be concerned about electrolysis warping the parts. I know it causes strange processes to happen inside the metal, and can cause parts to become brittle. Whether this is at all relevant to gauge blocks I couldn't say, but I'd shy away from it unless I was sure. Maybe try one, and see if it warps at all? |

If a gauge block is put under enough stress to break it, then perhaps electrolysis should be applied to the user. :) Besides, it sounds like we are only dealing with a few specs of corrosion here, any more than that and the gauge blocks will be toast anyway.

Brew up a strong cup of tea and place one of the blocks in it over night.This method works on removing rust on watch parts. Joe |
