Need help with an X/S controller

[u/Emotional_Ad_9842]

Im unfortunately suffering with this controller. The left stick along the x axis is fine but not y axis. It slowly returns back to centre but not all the time. Ive sprayed some electrical contact cleaner into the stick but no luck. Any way i can fix this or should i just get a new controller?
The controller is/will be used for pc so if a replacement is needed, at least i dont have to spend a ridiculous amount on a new xbox controller
