Ok, so I did a little searching and found that a lot of people use steam cleaners to clean their dragon's tank. I just purchased a hand held steam cleaner on Amazon for $35. I'm still interested to hear what other people use as a cleaner, how they do it and how often they do a full tank cleaning. Of course I will use the steam cleaner for when I do a full tank cleaning. I am also interested in hearing how (and with what) you clean the daily poop from the tank. I have vinyl tile in the bottom of my tank as substrate, so I've been collecting the poop with a paper towel and then going back over the area with another paper towel that has been sprayed with a vinegar/water mixture. What are your thoughts?
