Finally about 150 ml of the 750 ml D-Limonene that ended up in my friends cactus ooze for the first pull has been poured off. Better than nothing I suppose.

It's just a litre of sludge now. I suspect the limonene formed some kind of emulsion with the over-abundance of water.

What little limonene he got out is getting cloudy after adding vinegar. The idiot clearly messed up big time.
