If you can’t wait for Nintendo’s repair, these DIY fixes can temporarily stop Joy-Con drift. First, clean the analog stick: use a can of compressed air to blow dust out from around the stick, then wrap a piece of clear tape around your finger (sticky side out) and gently rub the base of the stick to remove grime. For a deeper clean, use a precision screwdriver to remove the Joy-Con’s back panel (voids warranty), then carefully lift the analog stick module and spray compressed air inside. Another trick: apply a tiny drop of electrical contact cleaner to the stick’s base (avoid excess, which can damage components) and move the stick in circles for 30 seconds. If drift persists, use the 'dead zone' setting in games—many titles let you adjust the analog stick’s sensitivity to ignore minor drift. Remember, these are temporary; for a permanent fix, use Nintendo’s free repair program.
