Papa Hemi Posted August 19, 2010 Posted August 19, 2010 My old fountain, on TV duty, has a scratchy volume control. I need to address this rather than saying, "I've gotta fix that!" every time I turn it on. Q. What is the best way to fix a scratchy pot? I have no proprietary solution for this, but I have WD40, turps, meths, soaps of various types and water in the tap. Any assistance gratefully received.
Owen Y Posted August 19, 2010 Posted August 19, 2010 WD40 will probably work (it's a pretty aggressive cleaner/lubricant) but I'm afraid that it will leave an unwanted messy residue & possible long term problems, eg. risk of shorting. Unfortunately, a low-residue, light cleaner suitable for non-metal surfaces (ie. a carbon wiper track) should be used... such as one of the Caig products, eg. Faderlube

CRC attracts dust, so graphite spray should be used instead. That's for locks anyway.

Then I read the first line "My old fountain..." hahahaha Sorry Papa H for going off topic, but I have always used a switch cleaner like the one crc has, seems to work ok.
Papa Hemi Posted August 20, 2010 Author Posted August 20, 2010 thanks for the feedback. The title is intended to amuse and catch the attention, however "my old fountain..." was unintentional but fortunate. Im pulling my fountain... apart at the moment.

little blue penguin Posted August 20, 2010 Posted August 20, 2010 Well done. I used to have to take penicillin when my knob was scratchy.
serioushifi1553552742 Posted August 20, 2010 Posted August 20, 2010 Actually back when I was a AEtrician we used a special contact cleaner for engine management computers. Used to work really well. Will post the name of the product once i remember it.

pasdesignal Posted August 22, 2010 Posted August 22, 2010 CRC make a product called 'Precision CO Contact Cleaner' which is the best stuff for the task. Spray into the pot, from inside the chassis, and turn the pot rapidly as many times as you can handle. But- I recommend replacing it with a sealed unit and not have to worry about it untill 2030.
