Paperclip always works good to clear the hole. Also helps getting the heating element centered. Alot of cartos comes with the element bent over to one side inside the carto. I like to get them nice and straight.
A tip I learned right here on ECF. I use Crest Pro Health Mouthwash, the blue kind, to clean my attys and cartos. I soak them for about 20 mins, aggitating them a few times. Then I dump the liquid, fill with water and soak for 5mins, aggitating of course. Then rinse them a few times under the sink. Blow them out and let em dry overnight. They DO have a minty smell afterwards but they do not taste minty. Tastes like a brand new carto.
