They must have changed the recipe. They all used to be just carbon tetra chloride.
When I was a kid, we used that stuff to kill insects for an insect collection. |

I use a product sold under the NAPA name, A quick drying electronic parts cleaner, sold at automotive stores that carry the NAPA line. Works very well, and I have used it on vintage D-104s with vary good results. R**** S**** did sell a very good cleaner, it wasn't the TV tuner cleaner, not sure if they still carry it. |

I use Deoxit D5N or Tefrawn by Rawn. You really don't weant the cleaner to dry. Tefrawn Stays there to lubricate and displace and prevent moisture build up.

Good plan. I was just going to get some of tuner spary at Rat shack. My old 2000 GTL had dust in the pots for volume and squelch, actually I should clean all of them. Would it work to spray with just the knobs off with one of those small straws and let it run down into those ? Thanks, Jim |

Slugo4449,
Carbon Tetra-Chloride (CTC) was used as one of the BEST potentiometer cleaners. But it was discovered, I believe in the mid-1980's that Carbon Tetra-Chloride was a TOXIN, causing certain types of cancer, for example, my Father's leukemia diagnosed in 1977. After working for [then] NY Telephone Company for 25+ years as a splicer and using CTC in a gel form to remove the day's (or night's) grease/oil/dirt from their hands and/or arms it was determined as the cause for his leukemia, which thankfully (our Lord Is powerful) went into remission in early-1980 -- yet it may also be the cause of his current kidney cancer, who knows for sure(?). I remember as a child always seeing the big yellow tube of "tetra-chloride" in the garage and in the basement in his shop.
So, to the best of my knowledge, the government put a warning on it and this is why CTC is no longer used in "parts cleaning" environments. |

biskybabyusa,
the way to clean the pots on your 2000 is to remove the bottom cover of the radio, wrap a cloth around the back of the pot to catch any overspray, and using the little red tube attatchment; spray right into the little hole on the back.
if there is no little hole; look at where the wires are soldered onto the pot, and you will see a small slot where you can access the inside of it.
use short sprays while turning the knob back and forth quickly.
wipe up any excess spray, and be very careful not to get any on the meter or channel display as it may dull the finish.
i sometimes use some masking tape over them.
good luck,
matt |
