Tools of the Trade: Rust Removal
Tom Conroy about tool repair. He talked about all sorts of tools and repair techniques, and during my session, briefly touched on rust removal. Conroy recommended putting a rusted tool in citric acid for not more than two to four hours to clean the rust right off. He said that the same result can be achieved if you leave a rusted tool in vinegar for around two days. Conroy also hypothesized that Sprite might work just as well, considering it's mostly citric acid. Yikes, somehow that gives extra incentive to lay off the soda for the new year!
2. Immersing rusted needles in Lemon Juice, and checking their progress once each day for a week.
3. Scrubbing needles with the lemon juice & salt mixture (wearing a glove & holding with pliers) for a couple minutes each day, when I check the other experiments!
