Carefully read the instructions on the back of the can before you start your cleaning task.
Hold the can in an upright position. Do not shake or tilt can before or during use – this can result in dispensing the gas in its liquid form. You can tell if you are dispensing the gas in its liquid form when you see white come out of the straw. You also may want to start off by giving a quick 1-2 second blasts to clear and make sure you won’t dispense liquid gas.
Use in a well-ventilated area.
If you are cleaning anything that has a power source, make sure to first unplug the item and allow the unit to cool off before proceeding. Then allow an hour for the gas to dissipate before plugging the fan back in.
