This post is a tutorial and a story.
I have a bunch of old skeleton keys sitting around my house, which I use to make necklaces for my online vintage shop. Every once in a while, I’ll come across a super rusty key like this little guy here. Look at this poor chap! It’s the rustiest key I ever did see; completely rusted from bow to pin, but so beautiful. When I found this key, I knew I had to try to remove its rust and allow its original color to be seen again. I could have used all sorts of abrasive chemicals and toxic substances, but instead I put Little Rusty through two milder treatments. I put the little key in a dish and grabbed two items.

The first: salt. And of course the packaging has a lighthouse on it. Would you expect anything less from me? Although that lighthouse model is a little odd…

The second: lime. I had read that, if you combine these two ingredients, it can help remove rust from many items, including old skeleton keys. So with the little key in the ceramic dish, I covered it with salt and added enough lime juice to create a slushy mixture, similar to a granita or shave ice.

I let it sit for about four hours in this mixture, then I took the thing over to the sink, grabbed a brush and a sponge, and with lots of time and elbow grease, I was able to take off quite a bit of the rust, exposing the real color of this pretty steel key!

But I knew it wasn’t the end. The bow was still pretty dark and so was the collar, all the way down to the pin and all over the bit. So the next day, I tried one more treatment that I had heard works well on keys. I covered the key in baking soda and mixed in some fresh lemon juice to make a foamy paste.

I let Little Rusty soak in this for about an hour or so, and then gave it a good, long scrub with that toothbrush you see there (obviously a toothbrush that I used specifically for this project, and not for teeth). And finally, Little Rusty looked a little more like himself again.

As you can see, it looks better than it did after the first treatment (and much better than it did when I found it), but not everything was removed. The bow (the top part) had some especially stubborn patina on it, as well as the bottom portion of the stem and the collar. I will try another lemon and/or lime treatment on it soon with a wire brush instead of a sponge and a toothbrush, but I think this little guy has gone through enough scrubbing and treatment for now. I’m just glad I could give this lovely little key a new life!
And to close this post, I just wanted to let you all know that I finally created a Twitter account. Follow me @ambervonnagel (because my upcoming book will be printed under that wonderful name)!
All the best,
