Tools of the Trade: Rust Removal Failure


Well folks, I'm embarrassed to admit, as it turns out, I'm not much of a scientist! Maybe next time I'll complete an experiment before I share it!  In my last post I wanted to test a couple rust removal theories, and chances are they would have been successful, but I got busy and forgot about my little containers.


I did check them on day two (top photo) and day four (above). Yuck! On day two the rust seemed to be flaking off nicely, but four days seemed to be far too long. Later in the week when I rinsed the containers out I was left with poor mutilated needles that were mostly eaten away beyond repair!

I'd say if you're going to try to remove rust in the future, do as I did and try your method on something that isn't valuable to you. Better yet, follow Bob or Patrick's advice! In the comments for my original post Bob recommended Ospho, a product that can be found in most hardware stores, and Patrick recommended soaking rusty objects in coke. I have actually heard of the latter method, and I'd be confident in trusting their suggestions!

It still was an interesting experiment, and thanks for sharing the frustrating outcome, too, :-)

The color in the lemon juice container looks interesting. The vinegar container seems to have a redish brown which is what you would expect. Is it just a trick of light, or has the lemon juice really turned blue? Why blue?!

It was brave to admit the failure of your attempt - but very interesting to hear the outcome.
Perhaps the needles would have liked to be wiped and polished after 2 or 3 days. I'm sorry if they were valuable/favourite ones - I've lost all my "best" bookbinding needles at the moment, in the moving muddle (from my tiny room downstairs, to a bigger one upstairs - amazing how things get lost!), but I daresay they'll turn up.
Thanks for sharing your experiment and reminding us of the advice in the comments too.

ketchup is really good! The acid in ketchup used to break up the rust in our old pans
