Thumbs up Using older corroded RG-6 coax cables

I posted months ago how much signal loss there could be at the cable connectors and how cable technicians usually cut off the old ends and attach new connectors.

I went to use a very old looking, but undamaged coax patch cable between my drop amplifier to my HW-150PVR and found that it got only 2 or 3 signals out of many times that because the signal was getting ruined by the high resistance caused by corrosion on the cable end that was connecting at the drop amplifier. Light wiggling of the cable at the drop amplifier end was able to occasionally get a picture to come through to the attached TV.

I learned long ago from somewhere that applying a sequence of chemicals can eat away corrosion and clean a surface so I used the following treatments to the existing corroded coax connectors to make them work again (perhaps not exactly like new):

1. dunking in dry baking soda (sodium bicarbonate), physically shaking off the excess afterward by whacking the two cable connector ends against one another.
2. dunking in white vinegar (weak acetic acid) also shaking off the excess as above.
3. running warm or hot tap water (to rinse) also shaking off the excess as above, then drying by waving the ends at high speed through the air for slightly less than a minute.
4. dunking in isopropyl alcohol also shaking off as above.
5. dunking into Vaseline (to coat the cleaned ends to prevent further oxidation), then wiping the excess off with dry toilet paper scrunched into the connector ends.

Upon plugging in the connections, my Homeworx HW-150PVR immediately started to get its signals so that a TV channel was coming in (rather than the "no signal" graphic appearing on the TV screen).

I've been using this 1TB WD drive for over a year now with no issues (and no external power required):
