Thank you for all these great replies.

Ok, so I just did the first pull - 5 weeks after adding the lime.
I did it outside (that Xylene smells like death, but only took one whiff from a distance.)

Salted out with vinegar 2 times and once with water.

Now I have the vinegar/water/dmt.
At first it only smelled like Xylene. Left it for about one hour in the wind and then it smelled 50% of vinegar 50% of Xylene. This is because the turkey baster held onto some Xylene from that top layer.

Now, the plan is to evaporate that vinegar and dissolve it with 96% ethanol onto some leaf.
No sodium carbonate wash this time.

Will the Xylene smell eventually go away if I leave the vinegar with the cap off?
How long will that take? Not that I'm in a hurry, far from it.
Because... I wouldn't want to smoke Xylene now..

Edit: Ok, the smell is getting less and less..
I can't get IPA, that's why I won't be doing Sodium Carbonate wash, I only have 96% ethanol

pour your solution on a wide dish that has as much contact to air as possible and it will evap in a day, maybe even less, depends on the amount.

People have found fb'ing acetates with heat to be suboptimal. I'd suggest you add the sodcarb after evap'ing, dry again then pull with the EtOH.
