Question: How do I dispose of my gas cylinders?
Answer: It really depends on the state that you live in and their disposal regulations. Always vent the tank to make sure the all gas has been removed. For disposable cylinders take a screw driver and press the tip, hit the screw driver with a hammer to push tip in. Some companies also drill a hole in the bottom and top before throwing the tank in the trash or recycle bin. For refillable bottles return to us with the return label that is affixed to the bottle and have it refilled or just recycled.
