I have a 2012/13 128 grid, and when I turn it on after not using it for a bit, I really have to wail on the pads to get them to be responsive. Once I mash them for a few minutes it plays “okay” but not like it once did (or even like my 2009 64 does). What is the best way to take it apart and clean it so I can remedy this problem. I’ve read on different topics here to use isopropyl alcohol - but before I mess something up for good - I thought I’d ask for a bit more clarity and/or other techniques.
Thanks!
