I have no idea what the white stuff is.You mean the condensation from the cold air PE? Try holding the can further away - also, it shouldn't take more than a few seconds to clear off.
It was my cable box for my tv.um... is the aforementioned electronic on a level surface? cans of air needs to be level, and not pointed up or down.
Regardless, the limitation you mentioned is one of the many reasons I despise cans of air. Having to keep it level is just begging for an accidental drop when one is trying to clean out laptops for example, resulting in an unfortunate early demise for said laptop.
