Removing corrosion on the battery coils

[Styleking]

Ok so as I get into collecting I'm noticing that boxes stored for a long period of time often have corrosion. Is there any quick way to remove or lessen the corrosion? Thanks

For the most part battery leaks is the biggest cause of the corrosion on the springs and compartment no real quick way to remove rust I once got a box so badly corroded from battery acid that the tape deck inside was all rusty and corroded too

Thanks for the response Bill. I'm wondering if I should avoid a box with rust/corrosion? I know they have CLR for rust removal anybody have any luck with that? I'm getting into my full boombox ninja assasin mode to look for boxes all summer!

What I have done in the past for corroded coils and contacts is.
Remove the coils and contacts from the unit if possible.
Take a small container and pour in some Naval Jelly and let the corroded parts sit in the jelly for a few hours while checking it often.
It usually removes the corrosion good enough to restore electrical contact and makes the parts usable again.

Thanks Skippy. I'm going to have to get my hands dirty soon working on some of these things.

Sure and good luck!

for the very quick and easy ----
and temporary 'fix'

i have been gladly surprised at how little // momentary effort it always takes-
so make even the crappiest of coils and contacts come alive -

a minutes worth of a sanding nail file -
and some 1/2 minute with little jacknife blade

will clean most terminals -
at least enough to fire up a box

Baking soda, warm water and a old toothbrush.

For me WD40 and fine sandpaper worked like a charm .

Bumping an old thread...

I'm surprised that there isn't replacement battery coils available or is there? They all seem to be ruffly the same size and such.

Replacing them with new would make such a big difference to at least half of my ghetto-boxes.

Actually there is replacement coils available...just not where you think they'd be.

My M90 had corroded battery coils...I tried everthing under the sun including a metal brush for pipe soldering to no avail. It was in horrible condition. Then I went to my local thrift store and found a cheap JVC CD based boombox for $5.00 that had an indentically sized coil in it.

Brought it home and it matched perfectly

A little soldering later I had a perfectly new coil in an old classic and now loves devouring batteries once again.

I urge you to try this route if all home remedies fail. It's $5.00 well spent

There is another option. Look for old flash lights and remove the spring from the bottom of it. It's pretty easy to solder and secure it to the boombox. :

IIRC vinegar will dissolve the acid assuming the coils and contacts are not too bad.

One of the ingredients used in CLR is acetic acid (Vinegar)

Them dollar store flashlights will give ya an endless supply of springs.

That's correct!
