I recently was told of the fail-safe method of "fixing" cell 'phones which were immersed in water: Place 'em in a sealed zip-lock bag with a handful of (uncooked ) rice for a few days. The rice purportedly gets damp -- while the 'phone is dried to again perform.
The thought came, would this technique "work" for storage of iron (e.g., H&G) boolit moulds? Sure would seem easier than (my method) of spraying with Starrett oil after each use and then degreasing before the next.
Hence, I reckoned I'd ask if any of you pro's at casting have ever tried this, and if so, the result.
Thanks!
