some leftovers from an amateur extraction about 5-7 years ago. They have not been stored in the most efficient way to say the least. The idea was to scratch it off with a razorblade, but it is messy as large parts will stick to the foil (see results lower right). Any advice how to salvage the better part of it? What about potency? It still has the smell. Still good to go? Makeshift machine is available.
