Removing heat tint is not required maintenance for proper torch use. If the flame worker would like to remove the heat tint, simply rub a plastic dish-
Luckily, you can effectively clean the residue with a can of compressed air and a clean cloth. First, turn down the flame control to its lowest setting, then depress the butane nozzle at the top of the lighter where the flame distributes with a small screwdriver head, effectively depleting any remaining air or butane.
Look for local hazardous waste disposal facilities or community hazardous waste collection events where you can safely dispose of your butane torch.
How to Bleed the Air. In order to release the air from the tank on a butane torch, press in on the fuel valve using a small screwdriver, or similar tool, at the bottom of the lighter. A steady stream of air will hiss out.
If the pressure is not released after each use, it can build and build with every refill, meaning less and less butane will flow into the gas chamber every time you refill it.
Small, hand held plastic butane lighters (e.g. cigarette lighters) are not recyclable. The fuel should be burned off so the container is empty, and then it can be placed in the garbage.
The process works like this: Light the canister and let it burn until the gas empties. You never want to dispose of a butane can with gas remaining inside, but hopefully it's nearly empty already at this point.
The fuel gas, being at a higher pressure, can travel up the oxygen line and mix with gas in the hose, regulator and cylinder. If you light your torch without purging the lines, a burn back may occur with explosions in the hose, regulator, or cylinder.
Turn off the acetylene cylinder valve. Turn off the oxygen cylinder valve. Bleed both lines by opening and closing the torch body valves. Both the line pressure gauge and the tank pressure gauge should now read zero.
A: Most torches will "overspray" when you overfill them. If there is no spray coming from the end where the nozzle goes, then you are not overfilling and may have a faulting indicator. Helpful? Thank you for your feedback!
All refillable butane lighters have a valve on the bottom that works like a tire valve. Before refilling the lighter, you must push the "tire" like valve IN to purge/evacuate the excess gas and oxygen. The excess oxygen and residual gas left inside will seep out and make a "hissing" sound.
Get yourself some canned air like the kind you would use to clean a computer keyboard and give your lighter's jets a couple of quick air blasts to free up anything that may be clogging them. Then, take a q-tip dipped in isopropyl alcohol and gently swab the jets to eliminate any remnants.
Safe Disposal: If your lighter is not refillable or reusable, it can be safely disposed of in your regular household trash. However, make sure to completely empty the lighter of any remaining fuel and remove the metal parts, if possible, before disposing of it.
Bleed the Tank Before Refilling
This air prevents fuel from occupying the tank. Flip the lighter upside down and use a small screwdriver or a thin and narrow tool to compress the fuel valve and release the air. A trace amount of fuel may also escape. After the valve stops hissing, the air has been fully expelled.
You can do this with a screwdriver. or anything long and thin. Just press on the valve and let all the gas out. Once the gas stops coming out, heat up the lighter with your hands. Doing so, the remaining gas deposited inside. will open up and come out, ensuring that the tank is completely purged.
