How to empty 16.4oz propane canister with degraded threading?

Hello

I just found some old 16.4 oz propane cylinders in my closet, and want to get rid of them

Unfortunately, the threading around the valve, where the tank screws on to a grill, is badly rusted, and some are a little stripped

This happened due to their age, not through usage, and some of them are 1/2 to 3/4 full; this makes it impossible for me to recycle them--I DON'T want to blow anyone up

And, I cannot vent the canisters by connecting them to my grill and burning off the remaining gas, due to the bad threads/valves.

Is their another, safe way of venting the gas from them?

Thanks

    Take them to a propane supplier. They have the knowledge and experience to be able to safely deal with them under controlled conditions.

    You may inadvertantly cause a leak that you can't control or if you get liquid propane on your skin you could get very painful freeze burns. Let a pro handle it...

    Good propane dealers will accept old or junk tanks.

    Take them to your local fire department. They will be happy to handle your problem without having to fight a fire.

    The simplest way is just to open the valve, drop a match and run!!!!

    Just Kidding!

    Take it back to where you got it. They can handle it.
