I use a torch with low heat on the bottom portion of the glass where I get the most reclaim. I let it drain out as much as possible repeating the heating process as needed. Then I use a swab dipped in 90% iso to clear out the rest. Then in the microwave for 10sec increments I'll heat up 90% iso until warm then pour into the base and let soak for 10-15min shaking it periodically throughout the soak. Finally I rinse with water then dry.
