I have a remote for a VCR that was not being used. The batteries
leaked and left corosion on the contacts inside. (Alkaline
batteries). The contacts are not deteriorated, but are corroded.
What is the best way to clean them, and neutralize any chemical
reaction to prevent further damage?
Soapy water on a q-tip. Not too much, don't want to leave any water behind.
A small amount of baking soda will also help by neutralizing any acid and
acting as an abrasive, be sure to remove all of that too.
Sometimes need to scratch up the contact area with a x-acto blade or file if
corrosion is thick.
If it were really messy, you can often remove the circuit board and clean
all the parts in ISO alcohol then dry thoroughly then reassemble.
(a mild acid to neutralize the alkaline battery electrolyte)
Since the plating has probably been eaten away,the exposed spring metal
will oxidize.Perhaps a light coating of Vaseline will help there.
I find that Duracells leak more than Everready or Fuji cells.
I no longer use Duracells.
