Cleaning Joy-Con analog sticks regularly prevents drift. Remove the Joy-Con from the Switch and turn it off. Use a can of compressed air to blow dust out from around the analog stick—hold the can 6 inches away and spray short bursts while rotating the stick. For sticky residue, dampen a cotton swab with isopropyl alcohol (70%) and gently wipe the base of the stick, where it meets the Joy-Con case. Avoid getting liquid inside the stick module. Use a dry cotton swab to remove excess moisture and let the Joy-Con dry for 10 minutes. Reattach the Joy-Con and test the stick—if it feels sticky, repeat the process. For deeper cleaning, use a precision cleaning tool (like a Joy-Con analog stick cleaner kit) to reach debris under the stick cap. Clean sticks every 2-3 weeks for regular use to maintain responsiveness.
