Step 3: Suspend Rusty Item
Suspend the item in the solution so as much of the surface is exposed to the water as possible. I used twine, but you can also lay a board across the top of the container and hang or clamp your tool in place.
Make sure to use nonreactive plastic, wood, or twine. If the object won’t fit completely in the container, leave part of it out of the water and clean it in stages.
