Paul has mentioned in a topic about cleaning potmeters and VRs this excellent product: “WD-40 Spray and Stay GEL LUBRICANT”, to lubricate potmeters after having first cleaned them with some ordinary contact cleaner, and then dried them.
According to the site on Amazon it should have a new look now (including red instead of yellow spray top), and the name changed to “SPECIALIST GEL LUBE no-drip”.
Can you confirm this has the same properties and is still okay for electrical contacts ?
As the product is not so easily obtained here in Europe, I would have to order it via some e-shop, including transportation costs. Therefore I would like to make sure the product is exactly correct, and does not have negative effects on the internals of the potmeter. Also on longer term.
It appears to be the same minus the nozzle, did you end up purchasing this stuff?
Indeed, I finally arrived at purchasing the “WD40 Specialist SPUITVET-GRAISSE EN SPRAY” through a local Do-It-Yourself store chain. The WD40 Specialist range of products has become available in Belgium relatively recently. As I’m living in Belgium, the name is respectively Dutch and French. The Article Number found in small print on the spray can (with foldable nozzle !) is “31895”. Anyway, the image in the yellow circle on the can is the same as for “WD40 Specialist Gel Lube No-Drip”: a pulley with 3 segments of chain hanging down from it.
The gel lube has a very good tenacity on the rollers of our sliding gate ;-). My guess is that also car door hinges would be excellent use cases.
I am planning to use it on slider potentiometers, as present in transistor radio’s. On a Philips taperecorder I have been using Kontakt 61, but I am curious to find out if the WD40 Specialist Gel Lube No-Drip has the same effect.
Right on, I found some matching that description locally. I will pick up a can for radio work.
Interestingly I went to verify my fact that WD-40 was originally designed as an electrical contact cleaner, however it was specifically designed to protect the outer skin of the Atlas missile.
Kontakt 61 appears to be a professional product so it would be interesting to see how they compare.
