I have had joycon drift in both sets of my joycons for at least a year. It actually made me switch to the pro controller full time.
But I watched a video on Nintendo Life (hello, loooovely peeeple), and now I'm cured.
You need to lift up the membrane underneath the joystick with tweezers or a paperclip, spray a very small amount of electronic cleaner in there, and rotate the stick for a full minute. Then let it dry for at least an hour. Make sure the controller is off and that you don't press any buttons whatsoever as sending electric current through the controller is the very last thing you'd want to do.
Both my neon and gray set are now perfectly fine and I haven't had the slightest bit of drift since.
