Once more looking to pick the collective brain here: I have a few old rusty braces I want to restore. The wooden parts cannot be removed, so I want to find the most efficient way to submerge the braces in Evapo-Rust while keeping the wooden parts protected. For instance, I could use plastic wrap (would it survive the soaking without disintegrating?) and make sure the areas were the wood meet the metal are wrapped tight so the liquid doesn't seep through. I've also heard of wrapping the metal parts on a towel soaked in the liquid; but I am not convinced that would produce the same results as full immersion.
Which other ideas would you suggest? In theory Evapo-rust doesn't damage wood, but it's still a liquid after all, and I don't want old wood to get soaked unnecessarily.
