Swim got about 3g of yellowish spice and  from the above mentioned bark.

  Infundibulum or anyone... if the ammonia wash doesn't help w/ the oils,what is the ammonia wash used for? trace amounts of lye?

Swim doesnt care about the crystals being yellow n-oxide... but he would like to take further steps to clean it up and it doesnt sound like the ammonia wash is the way to go,is that correct?

  Just re-x ?
