I got a new bottle of compressed air spray last night and have always cleaned my PS4 with such a spray…
So far it has never been the case that the gas escapes when cleaning as a liquid
Therefore, I now ask out of pure interest whether the PS4 would be harmful if the gas comes out as a liquid.
Sometimes I get scared, so I spray a little bit on my hand or on something to make sure.
The stuff in the can is made in such a way that it becomes gaseous when it appears. The pressure drop between the state in the can and the state outside causes that. Furthermore, when the air / gas is compressed, the moisture is extracted from the medium by means of a desiccant. This happens with every gas that is filled into pressure vessels.
