How to Remove Rust Using Electrolysis

Step 8: Allow Time to Work

Step 8: Allow Time to Work

Soon you should see tiny bubbles coming off both your tool and the anode, and eventually the rust will start flaking off or disintegrating. I left this small tool on for about five hours, but larger or rustier items might take a day or two.

Electrolysis only works as long as there’s rust, so you don’t have to worry about leaving it too long. If it isn’t working, turn off the charger and check the clamps to be sure there’s a solid electrical connection. For extremely rusty items, you may want to scour a clean spot for the clamp to connect.
