Have an old 30 lb (?) cylinder of R12, with maybe 1 lb left- cant be 100% sure as done know the ECACT tare weight of the cylinder- I believe its 9 lbs, thats what a Dupont tech gu told me, but he didnt have a more accurate weight (eg, 9.25lb, etc). I shook the bottle, and felt no "slosh around" weight/noise/etc. But, I just cracked the spigot, and heard a healthy psssssst. So, when youre down that low, is it expected to get ALL of it out and suck it into the car's ac system ?

Best way is to put the drum in a 5 gallon pail of hot water.
dang, right, Doug!! I just now remembered that from a long while ago, a secret explained in this forum. man, I totally forgot! Thnaks , man!

just thought of it- easier than lugging a few buckets full of hot water outside, cant one place the can in the sun for an hour or 2, not to let it get too hot?? Heat is heat.

You have to realize there are a lot of DYI'ers on this forum and can not justify purchasing all the toys us pros use. The hot water method is inexpensive and easy to use.
Well, I appreciate the advice guys, just the same. Your intentions are good. No way I'd spend $$ on such a one time use "blanket", though. You see, like I explained, I have a scant amount of r12 left in the tank- why would I get a blanket? Geez- maybe less than 1/4 lb of R12. Hot water, the sun, or have a few chickens sit on it for a few hours- whatever. It's basically an empty tank. Just was wanting to know how best way to extract the last , almost futile bit out, thats all.
Oh- once Im done with this tank, Im not gonna even deal with r12 anymore..........(I hope, I think)

I just read somewhere that a tank is considered empty when 5% of capacity is reached but then again, what do you do with it then????
Wow, wp, I didnt know that!! Guess mine should be considered empty, as geez, Im really down to the last bit. Maybe Im fussing over nothing for sure!! Anyway, will try the sun, or some laying hens maybe, and see what happens. I normally use small cans anyway, blankets wont be of any use.......
