WD-40 is an OIL, not a CLEANER. Because of its nature (to penetrate everything), it will let the wiper move some dirt off of the resistive strip. However, because it *is* an oil, it leaves a huge deposit of (what else) oil behind, to which every passing speck of dust and dirt will stick. Pretty soon afterwards, this coating of oil will cause more problems because of the gunk buildup. This deposit will be difficult for any cleaner to remove, and will probably necessitate replacement of the pot. From what I understand about WD-40, it's actually a combination of several things. I believe the formula is a trade secret, so nobody knows *exactly* what's in it. That by itself is enough justification if you don't feel comfortable using it on audio gear. One thing is for su the "WD" stands for Water Displacing. So, at least according to its name, it's supposed to remove water from things. Some info I found on the net says it may do this due to the surface tension of some of its ingredients. It also seems to contain a small amount of some kind of lubricant, although I found several people saying it's probably not enough for it to be useful as a lubricant. And it may also contain some surfactants (useful for cleaning things) and something that leaves a protective coating to keep out moisture in the future. Basically, as far as I can tell, the purpose of WD-40 is to remove moisture from that rusted bolt you can't turn, add a little lubricant to make it easier to turn, and add a coating to hopefully reduce rust a little in the future. So personally, I wouldn't use it on audio gear. It sounds like it has some properties that are useful and some that are not. However, I should point out I've only had the two semesters of college chemistry, and the lab for the second semester was one of the two reasons that at the end of my senior year I wasn't really sure if I was going to graduate or not. :-) - Logan |

** Do the test I suggested with a length of insulated wire, XLR and pre-amp. Then think how a voltage is created in the coil of a dynamic, mic sent down the cable to the pre-amp and is amplified. Then realise that the connecting cable is just an extension of that same coil. Recall that a dynamic mic hums when placed near an AC power transformer ( except for those with effective, internal hum bucking coils). ok, got that. but what about when the cable runs next to an AC transformer? that's the part that i don't quite get -- i don't see how it could induce current in one conductor in opposite polarity with the other. btw, i don't understand the voltage vs. current induction thing -- my physics book says a moving B field will induce a /current/ in a coil. what am i missing? thanks, chris deckard saint louis moe |

"Michael" Phil Allison "Bob Chandler" I've actually seen a couple people use WD-40 on a sctachy pot. I've never tried it myself for fear of gunking it up but it did make it quiet. I don't know what happened later. Is it as bad as I think it would be?? I'm afraid to try it on anything I own. ** Those who do not suffer from such irrational fears find there is no problem. WD-40 is an OIL, not a CLEANER. ** Absolute bull**** - the solvent part ( about 85% of the mix) is very much a cleaner. Because of its nature (to penetrate everything), it will let the wiper move some dirt off of the resistive strip. * More bull**** - the solvent *dissolves* the grease and carbon particle mess that builds up on wipers. However, because it *is* an oil, it leaves a huge deposit of (what else) oil behind, ** Moving the wiper after using WD40 displaces the (very thin) oil from the contact areas. to which every passing speck of dust and dirt will stick. ** Drivel. Pretty soon afterwards, this coating of oil will cause more problems because of the gunk buildup. This deposit will be difficult for any cleaner to remove, and will probably necessitate replacement of the pot. ** Anti- WD40 freaks will make up any lie. Irrational fears?!? ** Absolutely - plus barrels of bull****. It's just common sense (and 25 years experience in the electronics industry). ** You have none of the former and have learn little from the latter. Yeah, it can be a quick fix for the evening, but it will cause problems in the long run. The BEST thing to do is to take a couple of minutes (not seconds) and move that pot over the length of its travel over and over. This will clean it up enough to where it will get you through the night, until you can get some cleaner. ** No doubt some spray consisting of a grease solvent and a light ( non silicone) lubricant - but not called WD40 and far far more expensive. ...............

"Mike Turk" WD40 always comes through for me to clean pots; unlike many other cleaners or lubricants I have tried. It was taught to me by an absolute genius of an engineer who never steered me wrong. I will continue to use it. ** Tye voice of sanity. ............ Phil |

Any cleaner is just a temporary measure. ** And life is but a temporary state for mankind.

"Geoff Wood" Clean and lube pots and sliders with Caig Cailube. ** Which is a hydrocarbon grease solvent plus light oil.
