Hi folks! I just tried to wax the N900 with some (very small amount) of Autoglym aquawax. The N900 looks and feels NEW! This is a good way to remove some scratches especially on the bezel and screen. In fact, the touchsreen feels smoother and so nice to use. I did not notice any discoloration or smearing anywhere, so, I guess it's safe to wax our N900. Again, only a very small amount of wax applied with microfibre cloth.
Note: Autoglym aquawax is a high quality carnouba wax - I don't recommend using other harsher auto wax.
By the way, I just wondered, any other weird things you've done for your N900?
Nope, it feels very smooth when swipping the touch screen. (Again), I used only a very small drop of Autoglym aquawax - I wouldn't recommend stronger wax.
The screen feels better responsive - maybe because the wax removed any contaminants, or just psychological effect
