| What to use for cleaning switches, pots and rotary encoders? |

Vaseline -the same kind as some people use as a skin moisturizer? Won't this act as an electrical insulator on the pot's carbon track? I assume that's where the vaseline is applied in order to make it glide easily? Well, if this works at least it will be absolutely no problem to get hold of! |

I can say this is for the ball bearings, if your multimeter uses these, in the range switch outer tracks. This is how some manufactures ship their products. |

So the vaseline is used only for the mechanical parts of the multimeter range switch and the shaft in the potmeter, not on the actual electrical connection? This probably means I have to open up the pot to make sure the vaseline only goes to the metal shaft, and the Deoxit F5 or Oszillin T6 only goes to the carbon track? UPDATE: another thing: won't vaseline "melt" and become more like a liquid when it heats up, and thereby flowing all over the place? |
| SeanB:
There are different grades of petroleum jelly, of different viscosities, so some are pretty liquid at room temp while others are nearly solid waxes. |
| analogix:
Which brand/type is known not to melt at room temperatures? Some good news about my "scratchy" (as in feeling like it scratches when moving aound) -the Deoxit F5 seems to have "settled" a bit, so the pot is a little smoother now. But still not as smooth as before. I might have to desolder and open it up to be able to lubricate the pot spindle with some kind of grease. |
