I have a small solar panel gathering dust, so I decided to clean some tools. Read up on electrolysis, so here it is.
The driver bits on the left are what I started with, and the ones on the left have had about 15 minutes of treatment.
Step 1: Setting Up
Positive (red) wire from the panel goes onto a bunch of old bike cables
Negative (black) wire got attached to a small copper wire from an old phone cable. The other end of copper wire went onto the piece I wanted to clean.
The plastic container is filled with water+baking soda.
Step 2: Let the Sun Shine on the Panel
depending on sun intensity, size of panel and parts involved it may take more or less time. See next step for before and after images.
Step 3: Enjoy! Before and After...
here is the results you can expect.
