This thread can be blamed on Dbosman for suggesting I get Vaporust and on Sweetpea for suggesting I document my experiences with the Vaporust and a rusty old mould.
To start with, I got this old 32359 mould off Fleabay with some other stuff. Two-thirds of the mating edge of the mould was covered in thick rust. There was and still is some rust in the cavities and on the face. This picture was taken after about four hours soaking in Evaporust.
If this mould can be fixed, it will throw a 115 grain 8MM plinking boolit.
Also pictured are some Lyman 310 dies which came in an assortment of FleaBay junk so rusted they couldn't even be disassembled. Also photographed after about four hours soaking in Evaporust.
Evaporust can be purchased at Autozone in quart containers. I told my brother I was going to get some and I priced it at an Autozone. He tould me it was more affordable by the gallon in his favorite little tool store, so that is where I got it. Evaporust is water based and reusable until it evaporates away or becomes inefficient at eating rust on steel.
The second photo is a bullet seating die which is so rusted it is seized. As found in a pile of junk dies.

The Evaporust directions say to remove all oil before use so I soaked the mould and 310 dies in strong dishwater made with Joy detergent. There clearly wasn't even a memory of oil on the bullet seating die.
After washing in dish soap and after rinsing off the Evaporust, I dried the mould and 310 dies in a dehydrator.
I also cleand, de-rusted, dried and oiled a bunch of 310 boolit sizing dies. They merely look rather nice when done, but they weren't really bad to begin with.
This thread will focus more on what to do with moulds and such which are so rusted as to appear to be worthless and restoring them to usability.
