My 8-year-old niece played on my PS3 at Christmas, and ever since the X button on the DualShock 3 controller has been very sticky and has made most games unplayable with that controller.
A Google search turned up lots of hits for instructions on taking it apart to clean it, but it sounds like a difficult and time-consuming job. Are there any easier ways to remove the stickiness?
Don’t be too afraid to open it up. I’ve had to open mine a couple times to replace thumbsticks destroyed by my son. iFixit has some great guides for replacing almost every internal controller component. The hardest part is getting the pieces that fit between L1/L2 and R1/R2 back in and secured.
