extracting THC from storage containers (mason jars)

After a few years of storing my wares in the same group of quart sized mason jars, I have noticed that there is a rather large buildup of crystals on the interior surface of the jars.... any suggestions as to how to collect this?? I was thinking maybe a quick iso wash, transferring the alcohol from jar to jar and then evaporating the liquid... Just curious if anyone has attempted anything similar?

that would work

First off, what a great problem to have. I've heard of people using lemon juice and pouring it onto wax paper, then letting it evaporate.That miight work.

I just use a razor blade. Instant hash.

I don't think I would rush the wash. .. it should be fairly clean resin. If it was mine I'd soak them for a while and scrape anything else that was left. Just what I'd do though

Everclear!!!! I just pour some in the jar, swish it around and pour into the next jar! Then I pour that into a pyrex pie dish and let it evaporate. Use a razor blade and scrape up the goodness!!! You could also use it to make Rick Simpson oil!

The way I see it, if I cannot consume it, I wont use it to make something I am going to consume!!!
