Do a Google/Yahoo/Bing search for the taryn spin. That will help in a few different ways. (remove excess
juice and remove water after a soak...speed drying)
fillered cartos I always soaked in hot water then did the flush as rdsok mentioned (I used a large syringe, dropped the carto in it and flushed hot water in and out of the syringe). After that, I would do the spin....if the liquid came out clear, I knew I got all the old
juice out, if not, back to another hot water soak and flush.
