What is the difference between tuner cleaner and contact cleaner?
micky
A friend needs the connection between her earphones and her cell phone
cleaned. She gets intermittent loss of sound, and iiuc wiggliing the
plug affects this sound But I don't think the solder connections are
bad, sine she had it cleaned a year ago for the same problem and it
worked well until a month ago.
It's some sort of non-standard, proprietary plug.
I'm not sure what to use, and I've long wondered about the difference
between tuner cleaner and contact cleaner. When she went to the
cell phone store, he used Keyboard Cleaner. I think the plastic is
really clean now
Thanks

Not much, since many vendors sell a product that does both. Sometimes
either one claims to "lubricate" the contacts, which means that it
leaves an oily residue.

Any particular cell phone? Not all EP connectors are the same. If in
doubt, use an air hose to remove the accumulated lint and filth. If
the contacts are exposed, sharpen a pencil eraser to a point and use
it to clean the contacts. Then use the air hose to remove the crud.

It's almost certainly the solder connection between the jack and the
PCB. Open her unspecified model cell phone, clean out the filth, and
resolder the connector. If the connector appears to be cracked,
replace the connector.

Sorry, but I couldn't find anything under proprietary plug.

I wouldn't use either type of "cleaner". Some 90% alcohol to disolve
out any grease left by the previous attempt to use tuner/contact
cleaner. If that doesn't work, tear the phone apart.

The theory was that the rubber might leave a sulfur containing residue that
will encourage corrosion.
You may agree or disagree but prudence (a fine girl) dictates caution.

Yeah. It's a Sony Ericson W580i.

Okay. Although the first cleaning caused it to work fine for almost a
years.

Okay.

I'll be able to find one for sale? (Don't waste your time looking.
After all, I haven't said it's cracked yet.)

I don't know what was used the first time. I wasn't involved. Right
now I don't even remember if she did it herself or she went to a phone
store.

I'd like that, but she may not trust me.

There are plenty of used cell phone dealers around.
<http://www.recellular.com/find/>
<http://www.recellulartoo.com/>
<http://www.dotcells.com/>
etc...
Plenty on eBay. New for $90. Used for $35 to $50. Some auctions at
low prices. Search for W580i.

In this case, probably not. Here's the connector:
<http://i01.i.aliimg.com/img/pb/174/796/331/331796174_570.jpg>
What's probably happening is that the gold contacts in the phone have
developed a layer of crud on them, and the sharp points on the plug
are not penetrating the crud. Solution... remove the crud. I have
several old phones with similar connectors. What I used was a tiny
screwdriver or plastic pick as a scraper. Some household cleaner
(i.e. 409), and a pair of overkill magnifying glasses so I can see
what I'm doing. The trick is to scrape off the crud until you see the
gold underneath, without scraping off the gold, or destroying the
plastic insulation between contacts. Start with a toothpick. Graduate
to a metal scraper if that doesn't work. You'll probably also find a
substantial amount of pocket lint inside the connector, which needs to
be removed BEFORE attacking.

The phone store usually has a spray can of something. I've never
bothered to check what they use.

I wouldn't trust you with my phone either.

I just googled for "contact cleaning eraser sulfur" and found no
warnings or horror stories. Sulfur is not going to attack the gold.
It might coat it, but then it has to leak out of the eraser in liquid
form, such as in the form of sulfuric acid. That's not going to
happen.
If the gold contacts develop a hard black coating, then some sulfur
was transfered. However, I've been using Pink Pearl erasers on gold
edge connectors for ummm... too many years, and have never seen the
problem. I wash off any residue with whatever solvent or cleaner
falls off the shelf (usually 409). I do NOT use an ink eraser, or
highly abrasive eraser that might rub off some of the gold plating
which is only 25-50 millionths thick.
There are those that favor DeOxit or Cramoline. I've had good luck
with both of those, but not when the contacts are exposed to a filthy
environment, as is typical for the exposed contacts on a cell phone.
The residue picks up the dust and lint, and turns them to crud. For
cell phones, I suggest using something that leaves no residue
(alcohol).

The only specific characteristic of "tuner cleaner" that I'm aware of
is that it's (was?) formulated to not be aggressive on plastics. Back
when mechanical tuners were made, they generally had phenolic wafers
to hold the contacts, but some used plastic or had plastic elsewhere
in the tuner. Tuner cleaners were generally pumped into various
openings in the tuner in order to flood and shotgun the whole assy,
rather than disassemble the tuner and apply the cleaner only to the
actual contacts. Other contact cleaners may or may not be tough on
plastics.

Use a plastic eraser (used for erasing marks from mylar sheets). These are
available at drafting and art supply stores.

A pretty shabby troll attempt.

What; if I'd taken you seriously? Do you want me to damage my

whereas contact cleaner might be more "aggressive".
I would get some red Cramolin (that's not what it's called any more -- can't
think of the name) and thoroughly clean the plug. (You can also put a "wet"
plug in the jack. The cleaner will migrate and at least partially clean the
jack.) This removes the oxide, which might be what you need done.

Some "tuner cleaner" I have used in years passed, also contained a
light lubricant (mineral oil, I think). Mechanical UHF television
tuners contained both rotary switches, and a whole bunch of tunable
reactive components (slug-tuned inductors?) which benefited by a bit
of lubrication.

I understand that some Cramolin products are still available from the
original manufacturer in Germany.
Caig Labs used to import Cramolin into the U.S. and sell it under
their label. In more recent years, they've been selling DeOxIt, which
is a similar product (but not manufactured by the makers of Cramolin).
The makeup of Cramolin and DeOxIt products is, I believe, a trade
secret. I've read several reports which suggest that both types of
products contain oleic acid as the (or an) active ingredient, as this
has a long history of use as a metal and contact cleaner.
