Tip For Metal Detector Electronics Maintenance....

[John-Edmonton]

Those battery terminals and battery ends do build up a layer of corrosion over time, similar to your car battery. Remedy?

Easy! Take a pencil eraser and rub it over each battery end and contacts on the battery holders. You might even notice some improvement in performance too!

If the corrosion is real bad, "usually greenish looking",
coke or pepsi, or whatever fizzy soft drink will eat that
stuff right up.
I use that on the car batteries too. For the little connectors,
I dip a Q tip in coke, and wash the connectors until clean.
After it's clean, I'll spray with some "deoxit". That
will improve the connection, and prevent corrosion for a
while. The deoxit is also good for any switches, pots, etc..
It'll take a "noisy" pot, and make it like new. Better than
the average "tuner cleaner"..

Arm & Hammer baking soda mixed with water is the greatest corrosion remover for batteries and connections. Works great on car batteries and leaves the posts and connections looking like new. Just don't get it inside your car battery.
