DeoxIT Contact Cleaner Spray - 2ml (0.07oz) for Electronics, Audio Equipment & Automotive Connectors | Restores Electrical Contacts, Prevents Corrosion | Ideal for Guitar Pots, Switches & Circuit Boards

The mfg of this product should thank the dude who wrote an internet article about the Switch Joycon drift problem and this product t being a possible fix.I used this on two left joycons that were drifting so badly that the game was impossible to play. After using this to lube up/clean out the con, the joysticks stopped drifting. One of the joycons has begun drifting again but really it has nothing to do with the effectiveness of this product.I've used this in my older PC fans that worked fine aside from some noticeable noise due to age. When manually spinning I met some resistance but a couple of drops of DEOXIT noticeably loosened them up.After numerous applications on various electronics I still have a lot of the tube left. So don't judge the price versus the size. You will find that a few drops here and there barely makes a dent, which i consider well worth it.
