Revive Rusty Tools with This Simple DIY Electrolysis Hack
We’ve all been there: discovering rust-covered tools languishing in the garage or worse, destined for the trash. If you’re someone who enjoys breathing new life into old items, there’s a winter project that might pique your interest: constructing your own electrolysis machine.
With a few additional components and some basic knowledge, you can create an electrically charged water bath that effectively removes rust from tools, kitchenware, and even car parts.
The best part? It’s surprisingly simple. We’ll guide you through creating an electrolysis machine in just six steps.
Before diving into the project, here’s a brief explanation of how electrolysis functions: Electrolysis operates by eliminating iron oxide, or rust, through an electrical charge transmitted via liquid. This process involves the exchange of ions, which causes iron oxide to detach from the metal.
In simpler terms, the combination of liquid and electricity turns rust into powder without harming the underlying metal.
Most of the materials required for a home electrolysis machine might already be in your home. For the few items you might need to purchase, such as copper wire and rebar, a quick trip to the hardware store should suffice.
You’ll need a plastic or glass container large enough to hold your items. Plastic buckets and wash bins are ideal for this purpose.
A power source is essential, such as a battery charger used for jump-starting cars. Some electrolysis machines even utilize a DC-output laptop charger (AC adaptor). A power source of about 12 volts is optimal, but exercise caution when handling these devices.
Short strands of copper or aluminum wire will be needed to tie your items together. Additionally, you’ll need enough water to fully submerge your rusted items.
A bent piece of uncoated steel or iron, like rebar, is necessary for the process. Safety is paramount, so ensure you have latex gloves and protective goggles on hand.
Fill the container to the appropriate level and mix in a solution of powder (1/3 cup powder to five gallons of water). Wrap the wire around the metal items you wish to clean and use the wires to secure them together.
Some people attach the free end of each wire to a board mounted over the container. Place the bent metal into the container so it stands freely, ensuring it does not touch the rusted items.
Connect the battery charger. Attach the negative (-) black end of the charger to the wires holding the rusted items. The positive (+) red end should be connected to the bent metal bar. Once everything is set up, turn on the charger.
If everything is correctly assembled, bubbles will form around the rusted items. Over time, rust will begin to flake off, turning the water thick and amber-colored. Depending on the size and condition of the items, this process can take anywhere from an hour to several days. Keep an eye on it—you’ll know when it’s ready.
Once the process is complete, unplug the charger, disconnect the ends, and carefully remove your items. Give them a thorough brushing, and they should be as good as new.
While this is a straightforward method for creating an electrolysis tank, there are other options available. For those interested in a more advanced approach, check out an informative YouTube video by WOOD Magazine.
