Default the importance of truly clean contacts

The following might be of interest. More likely it will provoke a "Duh. I
knew that." response.

Since last July, I've had occasional problems with my cell phone's charger.
The plug sometimes refused to make stable contact. The other day it got so
bad I couldn't charge the phone.

I stopped by the nearest Sprint office, and was given the runaround by two
smiling b****es. They had no replacement chargers, nor could they order one.
But they would be perfectly happy to sell me a new phone. I told them this
was unacceptable -- and illegal -- but they wouldn't budge. Oh, and they
didn't have the adapter that would allow them to download the phone's
contents to a new phone. "We don't stock that." Naturally.

The charger's plug was dirty and appeared slightly bent. One of the Bs took
it to the tech, who cleaned it. The cleaning did no good. (I could see only
a minor reduction in the crud.) I left the store contemplating various forms
of legally permissible revenge. (I intend to visit the nearby police station
and get their views on such things.)

I decided to give the plug a proper cleaning with DeOxit. It removed almost
all the schmutz. I also put DeOxit on the cleaned plug and shoved it into
the jack for a while. (This helps remove junk you can't directly reach.)

Needless to say, the charger is now working much better. It's not perfect,
but it's reliable enough. (I've ordered a charger that connects to the
phone's 18-pin interface jack.)

The moral of this? I guess it's that because the bottle's label reads
"contact cleaner", doesn't mean it really cleans contacts.

There's a reason Motorola used gold on the charger and battery
contacts of their public service radios - no corrosion, no oxidation,
extremely low resistance contacts.
