Question about LogiLink pressurized gas cleaner

So far, I have mainly used the spray to remove dust from the hardware in the computer. CPU, RAM, mainboard, etc. However, since the spray only works with compressed air, it should also be no problem to remove dirt from the parts of a projector. Since the liquid air evaporates when used as a gas, it becomes cold. So I wouldn't hold it too close to the objects to be cleaned. I would start with a distance of 20cm and then move closer for a short time if this is not sufficient. And only use it intermittently.
