Did you use sodium carbonate to wash or the convert to freebase?
In either case once it if freebase it will not dissolve well in water so you should be able to get the sodium carbonate to dissolve in water and then just filter out the crystals of spice. I am suspicious though that the white crystals are spice. My spice is ALWAYS pure white as is my intention.
