DeoxIT D5S-6 Spray, More Than A Contact Cleaner, 142g, Low-Med-High Valve, Pack of 1

The product does what the producer and friends of mine claim it does. It cleans electrical components and accessories on the spot. I use it for model railroading, and it is golden for keeping roller bearings clean and springs springing. The only complaint I have is the straw for the nozzle. It does not fit the nozzle, plain and simple. There is a video here, in which the manufacturer demonstrates to just cut the end of the nozzle with a razor blade, and then it will fit-Not. Tried that, trimming with the razor blade made the fit no better. I called the manufacturer, CAIG, for a replacement straw-they sent it. But still the same, the replacement does not fit the nozzle, either. Without the straw, that makes precision control impossible, unless you spray the product into a needle bottle (my only solution). They must have had a kazillion of these stars made overseas (I can guess where), and all of them our likely out of spec.

Worth the investment. I took apart my Quest 3 controller and sprayed a dap of Deoxit inside the joystick potentiometer. Not only does it clean out debris and fix my drift but it also give the plastics an oil lubricant layer to prevent future wear

This spray was very effective in getting rid of weak intermittent connections in the mode control of my stereo receiver. This can will probably last forever, you dont need to use much at all, just be sure to shield surrounding electronics and circuitry so that only your work target is treated. It completely got rid of the disconnects and it works fine now. Be sure to go on Utube and learn about your own receiver on the inside so you know what you are doing and how to get access to the oxidized potentiometers and switches.

Good quality item
