DCM
Today it was too cold to do anything outside so I decided to start extracting DCM from the last three gallons of DCM-containing stripper in my part of
the world. From a little over 600 ml of the goop I was able to get 500 ml of crude DCM. This is gonna take a while to do all three gallons.

Why do it all at once ? You know DCM is an escape artist (someone else's words from SM but sooo true!).
I mean, if you have a container that has proven to be able to hold DCM even in summer why not. Otherwise, you might want to consider keeping it in a
"stable" form and distill when needed.
I now have a lifelong supply in a metal can but I still remember losing one liter of the stuff I left in the HDPE bottle it was shipped in. The
plastic bag that held everything wasnt even affected by the DCM evaporating. I only noticed it was empty when I picked up what was supposed to be an
untouched bottle.

Herr Haber, I had that same thought after I posted. I’ve had these cans of stripper now for a couple of years stored here in the lab where I have no
AC, and they seem to have stood up to the desert summers just fine. I’m gonna do one more round of extraction then store the remaining stripper
either in a freezer or refrigerator for the duration. With so many OTC chemicals going away these days I try to get enough while I still can to last
for the foreseeable future.

Can't you just buy DCM from chemical suppliers?

Of course I could buy DCM, if I want to pay lab supply house prices. But what’s the fun in that? For me something like extracting DCM from stripper
is fun, instructive, and in the end I can say “I did this, I didn’t go out and buy it.” We can all buy any number of things OTC, but it’s
more fun to synthesize or extract things for later use or for your element collection. That’s the spirit of home chemistry.

DCM has disappeared from the high street paint remover products (in the EU anyways).
It is still available in 'professional' paint removal products. Try large car paint/accessory stores, industrial paint stores etc.
