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.
