Put your pan on the stove then fill it a little over half way with water. Get the water hot enough so it starts to bubble, but is not entirely boiling. Put the newly made air lock into the water and leave it in for about a minute. Remove it with tongs and set it on a cloth to cool down and dry. Curl up your vinyl tubing and put it in the water for about a minute as well. Remove with tongs and also let it cool down and dry. Take your vial of yeast in the tongs and put it in the water for about 10-15 seconds to sterilize the outside of the vial. Make sure not to leave it in much longer or you will kill the yeast. Place the yeast with everything else to dry. Lastly, dip one end of the funnel into the water, then flip it over after about 30 seconds. Place the funnel off to the side to dry. Empty the water from your pan and let it cool for a few minutes.
If you haven't already done so, make sure your 5-gallon jug is cooled down and let it dry. You might want to wait about an hour or so to make sure it is thoroughly dry.
