Spend the extra two dollars to buy the best and it should outlast you and the instrument with proper maintainence.
I've had some that only last for weeks before they crap out. Use the right stuff and if you still have scratchiness, replace it with quality parts.Ĭheap pots aren't worth the effort putting them in. The lubricant also prevents the hard steel brush from wearing through the pad made of a thin layer of carbon. Most pot cleaners either have mineral oil and/or silicone lubricants that makes them turn smoothly and prevents electrical arcing. If it went 5 years before getting scratchy, you can get another couple of years out of it before it needs replacement.

9 times out of 10 if a pot is just full of dust and oxidation. If you're not sure its the right stuff, look up the MSDS sheets and look for the lubricants. When you clean pots ONLY use a lubricating contact cleaner designed to clean and lubricate pots. The worst part is its now permanent because the carbon pad is stripped of carbon and there's no contact left for the brush. Improves the life of garden tools and car parts. Keeps tools and machinery working smoothly. Because it contains PTFE, it sticks to the surface, repels water and withstands temperatures of -20☌ to 100☌. It may seem fine for a day or two, but then the scratchiness is back worse then ever. Safe to use for cleaning plastics, rubber and metal. Anytime I've used a zero residue cleaner on pots (especially the newer plastic junk) It wipes the pot out in short order. Zero residue cleaners can leave the contact pad completely dry and even accelerate the loss of carbon from the pads.Īs an electronic tech I used all of these and more for decades. Since its a zero residue cleaner designed to clean carbon residue in switches, it should "not" be used to clean Potentiometers. This stuff is an alcohol based contact cleaner designed to clean and degrease things like switches and electrical plugs and connections which had carbon buildup and. When in doubt always look at the Material Safety Data Sheets and see what chemicals are in it.
