Brabantia, you can thank Ray for the procedure since mine is inspired from the one on his website:

I basically use extract with rubbing alcohol, but at the end I add water to the remaining liquid (50 % water for 50 % extract). I prefer doing this since I've found isopropyl alcohol to be too much dessicant for many plants.
I read that ethanol penetrates tissues and therefore do damages to plants.
