Okay so most everything has been tried already, but this works pretty well.
I started cleaning my carts in a 10 ml syringe. Just pop the mouth piece caps out, take the plunger out of the syringe and drop the cart in battery side down. put the tip of the syringe in a bowl of hot water and work the plunger as many times as you want. It seems to flush them out pretty well.
