I have recently revived an NEC VCR but I had neglected the remote
and leakage has left the blue corrosion on the contacts in the
remote. Is there any way to clean the contacts without wrecking them?
Usually it damages the plating on the contacts and the metal underneath.
You can try using a rough cloth to remove most of the gunk and they try a
pencil eraser. If that almost gets it, try an ink eraser.
I suggest that you may want to get a third party remote. I got a
Philips - Magnavox and it works with just about anything electronic and only
cost about $25.00. Even if you can get it working, it might be a good idea
to get the third party unit. I can eliminate the clicker clutter and it
gives you a backup. Keep the original. If there is a feature that is not
already programmed into the Philips, you should be able to program it by
letting the new one learn from the old one. I would not trust the old one
too long even if it appears you have it cleaned up.
common household vinegar;the "acid"(leakage) left was from an -ALKALINE-
battery,not really an acid,but alkaline(base).
Rinse well and dry,don't flood the remote and get water or vinegar inside
it.Use a Q-tip,small paintbrush,or an acid brush to apply the vinegar.

The spring end can be harder, but I think in one case, I folded some
tin foil (aluminum foil) 2 or 4 layers and placed that down so that it
touched the clean part of the original contact and the battery touched
In another case, I soldered in a new piece of "tin".
Bigger problem when you can't get at the contact, like the bottom of a

carbon zink or alki batteries in general
When these little costly batteries are brand 'new' ,
and just before installing batteries in your favorite toy,
you wipe the contacts clean on your shirt tail...
Q; If you were to not wash your shirt within a reasonable time would you
have holey damage ?
