It's time to open the beast, 'coz I need to clean the 'sometime unresponsive' controls

Here's the parts to clean...
It should be better like this

Now, let's try to remove that yellow dust everywhere on the game

...and try for the first time the 'magic sponge' I got
here.
Well, I'm not very happy with that cheap sponge, because it disintegrates almost immediately...
...which is normal, but that one disintegrates does it very quick
Anyway, here's a first result...
Mhhh, I've to found an other way for cleaning that stuff... I will use these magic sponges rather for flat surfaces, like control panel for example...
