Ok I just sprayed with the Cleaner I've shown above
on the Tyros 2 buttons, wheels, knobs, etc,...and wow what a big difference! .....
now buttons that were a bit sticky or needed a
firmer extra push now work fine with a light touch!!
I am so glad I did this bit of self maintenance on T2 using this contact cleaner worth every penny ...
works like a charm so easy you never know what
dirt & grime is in the air even in your own house
that can gum up electrical contacts.
